Breast Cancer
Research data from Tel-Aviv University, Medical Department update understanding of breast cancer

"A reverse transcriptase (RT) cDNA, designated HERV-K-T47D-RT, was isolated from a hormonally treated human breast cancer cell line. The protein product putative sequence is 97% identical to the human endogenous HERV-K retroviral sequences," scientists writing in the journal Neoplasia report. "Recombinant T47D-RT protein was used to generate polyclonal antibodies. The expression of HERV-K-T47D-RT protein increased in T47D cells after treatment with estrogen and progesterone. The RT-associated DNA polymerase activity was substantially increased after over-expressing a chimeric YFP-HERV-K-T47D-RT protein in cells. This RT-associated polymerase activity was...
