Christina Teng, Ph.D., is a molecular biologist who joined NTP Biomolecular Screening Branch (BSB) in 2008. She is a participant in the tripartite collaboration among NTP — comprised of NIEHS, the NIH Chemical Genomics Center (NCGC) and the Environmental Protection Agency (EPA) — that identifies key signaling pathways for environmental toxicants. Teng is also a member of a group that is involved in assay selection, design of the NTP initiative for High Throughput Screening and data analysis for subsequent recommendations on follow-up screening.

Before joining the branch, Teng was head of the Gene Regulation Group within the Division of Intramural Research’s (DIR) Laboratory of Reproductive and Developmental Toxicology. The group was focused on the elucidation of the molecular events associated with the regulation of gene expression by an estrogen receptor (ER)-mediated mechanism.

With more than 30 years of experience working on nuclear receptor mediated signaling, Teng was the first to clone the lactoferrin gene from mouse uterus and the human Krüppel-Like Factor 5 (IKLF/KLF5) from uterine carcinoma cells using a molecular approach. In addition, she successfully cloned the estrogen-related receptor alpha and demonstrated its involvement in the ER-mediated signaling pathway. In 1999 she received a patent for "Method of screening for risk of cancer using human lactoferrin DNA probe or primer."

Teng received her Ph.D. in 1969 at the University of Texas, Austin and has published 86 peer-reviewed articles in leading biomedical journals as well as 18 book chapters. She served as an Assistant Professor at the Department of Cell Biology, Baylor College of Medicine, Houston before joining NIEHS in 1983.
