Laurence Kedes to step down as IGM director

MAY 2, 2008

After serving 19 years as founding director of the USCInstitute for Genetic Medicine, Laurence H. Kedesannounced his resignation as director of the IGM effectiveJune 30.

He will return full time to research and remain at theInstitute as the William M. Keck Professor of Biochemistryand Molecular Biology.

In his letter to faculty, Kedes expressed his appreciation toeveryone affiliated with the IGM.

“I have greatly enjoyed working with the dedicated faculty,staff, students and supporters of the Instituteover these past 18 years,” he wrote. “It has beena privilege to work with all of you during mytime as director. I am not disappearing butintend to remain an active day-to-day partici-pant as a faculty member at the Institute towork with colleagues whom I greatly admire.”

Keck School of Medicine Dean Carmen A.Puliafito acknowledged Kedes’ role in buildingthe school’s reputation. “He is an innovativeresearcher, one that brought USC into themolecular era,” said Puliafito. “We’re pleasedthat we will continue to have an opportunity to

work with him as an accomplished researcher.”During his tenure as director of the IGM, Kedes oversaw

the recruitment of more than 20 faculty members and thedesign and development of the Institute’s research facilitiesand led the Institute’s participation in development of multi-investigator research programs including heart disease, hyper-tension, gene therapy and craniofacial defects.

Kedes previously served as chair of the Department ofBiochemistry and Molecular Biology from 1988 to 2002. Heis an internationally known expert in the field of skeletal

muscle and cardiac muscle molecular genetics.Among his scientific achievements was the firstisolation of a protein-coding gene from an ani-mal cell and the first determination of the DNAsequence of a protein coding animal gene. Hewas also a developer of the first federally fundeddigital Web-based database for storing and ana-lyzing DNA sequences.

A member of numerous scientific organiza-tions, including most recently as scientific direc-tor of the X PRIZE Foundation, he is identifiedas one of the world’s most cited molecular biolo-

To bolster after-hours security onthe Health Sciences Campus, USChas initiated a $3 million programto install ID-card-activated elec-tronic locks on 19 campus build-ings. Installation will begin aftergraduation and be completed dur-ing the fall semester.

Shane Hapuarachy, special proj-ect manager for the Department ofPublic Safety (DPS), said thatalthough security upgrades havelong been planned for the HealthSciences Campus, the April 2007Virginia Tech shooting added asense of urgency to the project.

“Virginia Tech was a big scare forevery campus and it emphasized theimportance of how we make surethat our campus is safe and secure.We just wanted to make sure thatwe are solving security problemsproactively and that we don’t have aVirginia Tech before we implementthese higher-end security systems,”he said.

Hapuarachy said the HSCSecurity Enhancement Initiative isprimarily designed to limit access tobuildings after regular businesshours. Under the new system, per-sonnel are issued USCard IDs,which serve as ID and are codedwith their access authorization forthe buildings in which they work orare authorized to enter. The cardspermit access after hours and alsolog the times at which the userenters and leaves the building.

“Department heads make thedecision concerning who is author-ized and whether you are someonewho needs access after hours. So ifyou come in at 10 p.m., and doorslock at 6 p.m., you need to be at anassigned access level or you won’tget in,” he said.

Because most students andemployees keep regular hours, hesaid that, “Probably 90 percent ofpeople on campus won’t be affectedby the change. But even so, conven-ience goes down when security goesup.”

DID WE SAY THAT?

Due to an editing error, an article in the April 25 issue of HSC Weekly misstatedthe type of degree conferred through the USC School of Pharmacy’s regulatoryscience program. The degree—doctor of regulatory science or DRSc— is a profes-sional doctorate.

To limit the inconvenience, he saidsecurity officials are working with usergroups and departments within build-ings to determine which doors will berigged with card-readers to permitafter-hours access—and what times aremost sensible to restrict access automat-ically.

Definitions of “after hours” will varyfrom building to building based on theneeds and practices of the variousdepartments and groups.

Hapuarachy said the planned systemrepresents a significant improvementover current security measures as itreplaces a decentralized, patchworkscheme of cameras and alarms with onethat is computerized, coordinated andfeeds information to a single centrallocation. It is also easily extensible, so alab with special requirements could beequipped with retinal or thumb scan-ners to provide additional security.

Even without additional measures,the new system will automatically pro-vide an audit trail of who entered andexited after hours—and when.

“That way, if something happens ordoes go wrong, you have an idea of whowas in the area,” he said.

Additionally, the new access controlsystem eliminates the need for physicalkeys—which over the years can becomelost or missing as employees leave theUniversity or move to other locationson campus.

“That’s a pretty severe security liabili-ty to have thousands of rogue keys outthere and to have no idea who hasthem—and it’s expensive to re-key abuilding. The new system addressesthat because when an employee leavesthe university, you simply kill theiraccess,” he said.

Hapuarachy said the new system alsoincorporates lessons learned from theVirginia Tech shooting because itenables security personnel to lock downbuildings remotely and instantly.

“If you have a shooter or other threaton campus, this gives DPS the ability topush a button and lock down buildingsimmediately. You don’t have to risk per-sonnel and go out to lock a buildingdown by hand,” he said.

A new study by USC researchers hasfound evidence that supports gender-related differences in the developmentand survival of metastatic colon cancer.

The study, which was published inthe April 15 issue of the journal CancerResearch, found that specific gene vari-ants linked to the development of coloncancer resulted in opposite survival out-comes for men and women.

Germline variations in the epidermalgrowth factor receptor (EGFR) DNA—a gene widely expressed in colonictissue—has been linked with poor prog-nosis in colon cancer, said Oliver Press,a medical student at the Keck School ofMedicine and lead author of the study.However, when researchers looked atEGFR as a prognostic factor, theyfound that it had opposite implicationsfor men and women.

“We expected to find that highexpression would correlate with a poorprognosis and faster growth of the can-cer,” said Press. “What we found wasthat men followed the expected trend,while women’s response was the oppo-site.”

Researchers analyzed 318 patients—177 men and 141 women—withmetastatic colon cancer treated at theUSC/Norris Comprehensive CancerCenter and the LAC+USC MedicalCenter between 1992 and 2003. All thepatients were exposed to similarchemotherapy treatments. Whengenomic DNA samples were analyzed,researchers found that women who hadspecific gene variants linked with highexpression of EGFR had higher overallsurvival rates, while men with the samevariants had lower survival.

“This is the first report to show that

the prognostic value of EGFR dependson gender,” said Heinz-Josef Lenz, pro-fessor of medicine at the Keck Schoolof Medicine and the principal investiga-tor on the study. “This may suggestthat, in the future, molecular markersshould be evaluated differently inwomen and men and that treatmentdecisions may depend on gender andnot only on molecular or clinical find-ings.”

Previous research has shown a protec-tive effect of female hormones in coloncancer survival, Press notes. The find-ings of the study indicate that hormonereceptors are important to signal path-ways related to the survival of patients.

The study is an important jumpingoff point to further research into howmen and women differ in response tospecific treatments, he said.

“Research will need to be done to

determine whether women and menrespond differently to certain cancertherapies,” Press said. “Down the roadwe may see targeted chemotherapy thatis tailored to get the best response frommale and female patients.”

The study was supported by grantsfrom the National Institutes of Health,the San Pedro Guild Research Fundand Charles Bittick.

USC study finds gender differences in colon cancer markers

SECURITY:After-hours access to be restricted

The first grade class at Pasadena’s St. Philip the Apostle School welcomed USC oncologist Heinz-Josef Lenz to their classroom on April 18 to learn about cancer and its treatment. During the visit,Lenz accepted toys that students—including Catherine Maldonado (left) and Hannah Crumpabove—had collected for “Andi’s Toy Box,” a program that provides children and young siblingsof cancer patients with puzzles, coloring books, magazines and other items to keep them occu-pied in hospital waiting rooms. “Andi’s Toy Box” was established by Brittany Ambrosanio to honorher 16-year-old friend, Andi Collins, who succumbed to breast cancer in 2003.

KEDES: After steering IGM for almost two decades, he returns full time to research

gists by the Institute for ScientificInformation. He has trained more than70 fellows who now hold professorialappointments at institutions worldwideincluding department and instituteheads at UCLA, Stanford, Yale, Sydney(Australia), Miami, Houston, Geneva(Switzerland) and Gunma ( Japan).

“Larry Kedes’ outstanding contribu-tions to the University and the interna-tional scientific community were

brought out in spectacular fashion atthe symposium held to honor his con-tributions at the IGM last October,”said Richard Bergman, Keck Professorand chair of the Department ofPhysiology and Biophysics. “Most ofthe lecturers were Larry’s former fel-lows. They all emphasized how criticalhis mentorship was to their futures asinvestigators. They also emphasizedwhat a wonderful humanitarian Larryis, and how he selflessly promoted their

careers,” Bergman added.Peter Jones, director of the

USC/Norris Comprehensive CancerCenter, said, “Larry Kedes is anabsolutely brilliant scientist who wasone of the forefathers of modern molec-ular biology. His recruitment reallytransformed the medical school. Thearrival of an individual of his caliber tothe Keck School showed that we wereserious about the development ofmolecular genetics.”

USC recruited Kedes in 1989 as thechair of Biochemistry and director of aplanned Institute for MolecularMedicine. Kedes quickly changed thenames of both the Department–toBiochemistry and Molecular Biology–and the Institute–to Genetic Medicine.His academic honors include being afellow of the John Simon GuggenheimFoundation, a Howard Hughes Medical

Institute Investigator, and receiving theDistinguished Scientist Award of theAmerican Heart Association, theProvosts Gold Medal from theUniversity of Messina (Italy) and theHenry N. Neufeld Memorial Award(Israel). In 2004 he received theUniversity of Southern CaliforniaDistinguished Faculty Service Award.

Kedes graduated from the StanfordUniversity School of Medicine. Hecompleted his residency in internalmedicine at Harvard’s Peter BentBrigham Hospital and conducted post-doctoral research at the NationalCancer Institute and at MIT.

Keck School Dean Puliafito hasappointed Elizabeth Fini, senior associ-ate dean for research advancement, asinterim director of the IGM. She willwork with Kedes over the next severalmonths to ensure a smooth transition.

Recent legislation has put into law the NationalInstitutes of Health (NIH) Public Access Policy,which requires all investigators funded by the NIH tosubmit an electronic version of their final, peer-reviewed manuscripts to PubMed Central.

“Failure to comply with the policy will jeopardizegrant renewals and future grant funding from theNIH,” said Bill Clintworth, director of the HealthSciences Libraries. “This issue is of critical importancenot only to individual investigators, but also to USCas an institution.”

The policy went into effect on April 7.By May 25, all NIH applications, proposals and

progress reports must include a PubMed Central ref-erence number (PMCID) when citing an article thatfalls under the policy and is authored or co-authoredby the investigator, or arose from the investigator’sNIH award. The reasoning behind the policy is toensure that taxpayer-funded research is freely availableto the public.

The new policy encompasses a movement in the

academic publishing industry called “open access.” Bydefinition, open access means that research papers areavailable on the Internet, permitting users to read,download, copy and distribute—with proper acknowl-edgement and citing of the original author—at nocost to the readers.

Fees paid by the authors, who can bill the cost intotheir grants or other funding, help to offset the cost ofopen access publications. This gives access to a world-wide audience, increasing the visibility of aresearcher’s work and institution.

“Open access challenges the traditional publishingmodel by removing price barriers to the reader andshifting them to the production end of publishing,”said Clintworth. “By making information available toeveryone rather than a diminishing number of peoplewho can afford to purchase it, the research cycle canbe shortened due to the wider availability of researchfindings, and society certainly benefits as a result.”

Clintworth said a major misconception about openaccess is that the peer-review process is not as rigor-ous as that used in traditional subscription-based jour-

nals. There is no difference. Open access publishinguses the same procedures. The confusion arises withpre-prints or manuscripts that have been “self-archived” in institutional repositories without beingreviewed and/or published.

According to Maggie Wineburgh-Freed, associatedirector of the collection resources division of theNorris Medical Library, one of the most importantthings for researchers to note is that they must retaincopyright of their publications in order to be able tosubmit them to the NIH.

“Do not sign away your rights when submitting forpublication,” she said.

More information on this issue, as well as a waiverto retain author rights, is available atwww.arl.org/sparc/author, the Web site of theScholarly Publishing and Academic ResourcesCoalition (SPARC).

New policy mandates NIH-funded studies must go on PubMed

If the shocked faces of several USC Relay for Lifeparticipants were any indication, the manifestations oforal cancer are horrific and, for many, very surprising.

Displayed on the back of the USC Dental Hygienetent, photos of receding, discolored gums andinflamed, affected palates and lips caught the eyes ofmany passers-by on the track at Loker Track Stadiumon April 5—and in under two hours, drew in over 60participants for free oral cancer screenings.

The screenings coincided with Relay for Life—anevent benefiting the American Cancer Society—inwhich teams of friends and families each send a mem-ber to walk or run around a track, relay-style, for 24hours.

Volunteer screeners and dental hygiene seniorsSheila Kuo Tiong, Valentina Shahbabyan, VaheNakashyan and Linh Ho said many patients wereunaware of the damage that oral cancer can cause, and

several had never received an oral cancer screening.“It is important for people to understand that they

should expect and request a complete oral cancerscreening every time they visit the dentist or the den-tal hygienist,” said Donna Smith, associate professorof clinical dentistry. “Oral health means more thanjust healthy teeth; it should mean total oral health.”

Besides addressing oral cancer concerns and receiv-ing complimentary toothbrushes and toothpaste,many participants received answers to other dentalquestions about topics such as the arrival of wisdomteeth and proper dental hygiene habits.

“Some people showed us stuff that had been both-ering them for a while,” Shahbabyan said.

After performing the national anthem and USCfight song during the relay’s opening ceremonies, sev-eral members of the Trojan Marching Band alsodropped by the tent for screenings. Brett Padelford,assistant director of the band, said that he and other

band members were happy to get screened.“We play instruments and use our mouths all the

time,” he said. “We’re glad to be here and grateful toget checked out.”

Even though rehabilitation still pro-vides a similar degree of improvementcompared to decades past, patients areentering—and exiting—rehab in com-paratively worse shape, said KennethOttenbacher on March 28 during thefirst monthly Rehabilitation ScienceSeminar.

Ottenbacher, professor and directorof the division of rehabilitation science,director of the Center forRehabilitation Sciences and senior asso-ciate dean for research and graduateeducation in the School of AlliedHealth Sciences at the University ofTexas Medical Branch, presented a talkon “Trends in Outcomes for InpatientMedical Rehabilitation.”

Ottenbacher’s research analyzed datafrom 1994 to 2007, using informationfrom both before and after the imple-mentation of Medicare’s prospectivepayment system, or PPS, in 2002.Based on each patient’s history, condi-tion and prognosis, the PPS allocates aspecific amount of money for post-acute care, including rehabilitation,before the patient receives care.

“From 1994 to 2001, length of stay inrehab decreased from a median 20 daysto median 12 days,” Ottenbacher said.“While effectiveness remained steadyand efficiency increased, mortality atthree to six months of follow-up alsoincreased.”

Ottenbacher hypothesized that mor-tality may have increased due to chang-ing referral patterns and possibledecreases in length of acute care staysbefore rehabilitation. Premature dis-charge also can be costly in financialterms, he added.

“For instance, say someone had astroke and was discharged withoutregaining good bowel and bladder con-trol,” Ottenbacher said. “They could geta urinary tract infection and get re-hos-pitalized. In the long run, that doesn’tsave money.”

The seminar came near the end ofOttenbacher’s month-long visit toUSC. The audience included facultyand students from the USC School ofDentistry divisions of Biokinesiologyand Physical Therapy and OccupationalScience and Occupational Therapy.

At a reception following the seminar,Ottenbacher said the two divisions areuniquely well-equipped to tackle thetough challenges he addressed in histalk, especially when working together.

“It’s a very complex problem, andthere’s no single solution,” he said. “Butyou have two of the highest rankedprograms right here at USC; I am veryimpressed with the caliber of the facultyand the graduate students.”

“We have a tremendous capacity toexpand our research potential throughcollaboration,” said Florence Clark, pro-fessor and chair of OccupationalScience and Occupational Therapy.“We have great opportunities to look atwhat the best combination of services isto help make patients more independ-ent.”
