Every year for the past three years, student interns Madelyne Xiao and Nikhil Gowda have competed in the Scientific Library’s Student Science Jeopardy Tournament, the annual science event for students that mirrors the popular TV show “Jeopardy.” And every year, for the past three years, Xiao and Gowda, who work with Randall Johnson, Ph.D. bioinformatics analyst, Basic Science Program Center for Cancer Research (CCR) Genetics Core, have finished in one of the top three positions.

TYCTWD Programs Strive to Make Science Educational and Fun

Scientist/Wizard magic show.

By Carolynne Keenan, Contributing Writer

Joseph Barchi, Jr, Ph.D., calls teaching “the noblest and most important profession.” So it makes sense that Barchi, senior scientist and head of the Glycoconjugate and NMR Section, Chemical Biology Laboratory, Center for Cancer Research, NCI at Frederick, would encourage his lab to offer a fun, educational program at Take Your Child to Work Day (TYCTWD).

HIV Integration at Certain Sites in Host DNA Is Linked to the Expansion and Persistence of Infected Cells

See caption for details.

Editor’s note: This article was originally published on the Center for Cancer Research website.

When the Human Immunodeficiency Virus (HIV) infects a cell, the virus inserts a copy of its genetic material into the host cell’s DNA. The inserted genetic material, which is also called a provirus, is used to produce new viruses. Because the viral DNA can be inserted at many sites in the host cell DNA, the site of integration marks each infected cell. Patients infected with HIV are currently treated with combined antiretroviral therapy (cART), which prevents viral replication in the majority of treated patients. When cART is initiated, most HIV-infected cells die in one or two days, and more of the infected cells die over a period of weeks to months. However there are some long-lived infected cells that do not die, which prevents patients from being cured.
