Aims: Breast and ovarian cancers are frequently associated with mutations in genes involved DNA double-strand break (DSB) repair by homologous recombination (HR). Risk factors for breast cancer often linked to estrogen-related pathways. Here, we studied the crosslink between estrogen HR pathway. Methods: We analyzed, using online annotation tolls, enrichment of candidate estrogen-upregulated am...

Estrogen-responsive endometrial cancer (EC) is prevalent in uterine cancer. Its precise molecular mechanisms remain to be elucidated partly because of limited availability estrogen-sensitive EC models recapitulating clinical pathophysiology. We previously established patient-derived cell (EC-PDC) spheroid culture with high expression estrogen receptor α (ERα). Using this EC-PDC, we study the tr...

Skin aging is a process influenced by several factors, including estrogen. Estrogen modulates the physiology of skin, and its deficiency in postmenopausal women accelerates skin aging. Administration estrogen can delay process. Phytoestrogens are estrogen-like compounds derived from plants that administered via oral as well astopical routes. Trigonella foenum-graecum, commonly known fenugreek, ...
