The steroid receptor (ER, PgR) content of breast cancer specimens is now widely used as an indicator for hormone sensitivity which is a prerequisite for endocrine therapy. Is it conceivable to extend this steroid receptor determination to other types of tumors in order to select patients who would eventually benefit from an hormonal therapy? It seems that most normal or tumoral tissues contain detectable amount of steroid receptors. The values of each receptor comprise a continuum from very low to relatively high, suggesting that previous considerations of hormone dependence on the basis of presence or absence of hormone receptors may be oversimplified. The steroid receptor concentrations are however higher in target tissues, and could be of clinical interest in endometrium and prostatic cancers. The date are however insufficient to draw firm conclusions regarding their usefulness for treatment.

Targeting optimal glycemic control based on hemoglobin A1c (A1c) values reduces but does not abolish the onset of diabetic kidney disease and its progression to chronic kidney disease (CKD). This suggests that factors other than the average glucose contribute to the residual risk. Vitamin D deficiency and frequent episodes of acute hyperglycemia (AH) are associated with the onset of albuminuria and CKD progression in diabetes.

Bone metastasis and skeletal-related complications are primary causes of mortality in advanced-stage prostate cancer (PCa). Epigenetic regulation, particularly histone modification, plays a key role in this process; however, the underlying mechanisms remain elusive. In mouse models, JARID1D was an important mediator of both visceral and bone metastases.

Persistent organic pollutants (POPs) are a group of organic chemical compounds. Contradictory results have emerged in epidemiological studies attempting to elucidate their relationship with breast cancer risk. This study explored the relationship between dietary exposures to multiple POPs and ER-positive breast cancer risk in the French E3N cohort study, using three different approaches to handle multicollinearity among exposures.

Backgroud: Salivary duct carcinoma (SDC) is a rare and aggressive malignancy with a generally dismal prognosis and no standard of care established, despite a known association with epidermal growth factor receptor 2 (HER2) and androgen receptor (AR) over-expression.
Case: We report the case of a 64-year-old female with extra- and intracranial metastases of SDC with evidence of AR and HER2 overexpression. After progression on first line chemotherapy, was administered neratinib, a pan-Erb2 receptor tyrosine kinase inhibitor.

Polychlorinated biphenyls (PCBs), a typical type of persistent organic pollutants (POPs), were previously widely employed as insulating and heat exchange fluids in transformers and capacitors. Despite knowledge of its adverse effects, the precise mechanism underlying PCB77 toxicity remains enigmatic. In this study, we utilized zebrafish as a model organism to explore the toxic effects of various concentrations of PCB77 (10, 200, and 1000 μg/L) and its molecular toxicity mechanisms.
