Estrogen-Regulated Lateral Septal Kisspeptin Neurons Abundantly Project to GnRH Neurons and the Hypothalamic Supramammillary Nucleus

While hypothalamic kisspeptin (KP) neurons play well-established roles in the estrogen-dependent regulation of reproduction, little is known about extrahypothalamic KP-producing (KPLS) neurons of the lateral septum. As established previously, Kiss1 expression in this region is low and regulated by estrogen receptor- and GABAB receptor-dependent mechanisms. Our present experiments on Kiss1-Cre/ZsGreen knock-in mice revealed that transgene… Continue reading Estrogen-Regulated Lateral Septal Kisspeptin Neurons Abundantly Project to GnRH Neurons and the Hypothalamic Supramammillary Nucleus

[Articles] Darolutamide or capecitabine in triple-negative, androgen receptor-positive, advanced breast cancer (UCBG 3-06 START): a multicentre, non-comparative, randomised, phase 2 trial

This study did not reach its prespecified endpoint for darolutamide activity in patients with triple-negative breast cancer selected on the basis of immunohistochemistry for AR. Further studies selecting patients based on RNA profiling might allow better identification of tumours sensitive to anti-androgens.

[Articles] Palbociclib plus endocrine therapy versus capecitabine in premenopausal women with hormone receptor-positive, HER2-negative metastatic breast cancer (Young-PEARL): overall survival analysis of a randomised, open-label, phase 2 study

With extended follow-up, palbociclib plus exemestane with ovarian function suppression continued to show a significant benefit in progression-free survival compared with capecitabine in premenopausal patients with hormone receptor-positive, HER2-negative metastatic breast cancer who had been previously treated with tamoxifen; however, no improvement in overall survival was seen. Given the progression-free survival benefit, the upfront use… Continue reading [Articles] Palbociclib plus endocrine therapy versus capecitabine in premenopausal women with hormone receptor-positive, HER2-negative metastatic breast cancer (Young-PEARL): overall survival analysis of a randomised, open-label, phase 2 study

Landmark atlas reveals how aging breast tissue shapes breast cancer risk

Aging is a privilege, but it also brings risks — including an increased likelihood of developing age-related diseases including cancer. Researchers have now created a landmark atlas of how healthy breast tissue ages, revealing key cellular, molecular, and genetic changes that may tip the balance toward breast cancer development.

Discovery of isoquinoline-tethered quinazoline derivatives with enhanced HER2 inhibition over EGFR

Human epidermal growth factor receptor 2 (HER2) is a critical therapeutic target for HER2-positive or HER2-dependent cancers. While several HER2 kinase inhibitors have been identified, achieving high selectivity for HER2 over EGFR remains a significant challenge. In this study, we aimed to develop HER2-selective inhibitors with enhanced cellular activity. To improve the limited cellular activity… Continue reading Discovery of isoquinoline-tethered quinazoline derivatives with enhanced HER2 inhibition over EGFR
