Recent studies have shed light on the pivotal roles of estrogen in various pathophysiological processes related to kidney diseases. However, the precise mechanisms governing the estrogen actions remain enigmatic. The downstream impacts of estrogen primarily hinge on estrogen receptors (ERs), namely ERα (NR3A1) and ERβ (NR3A2). Building upon our previous finding that ERβ participates in subcutaneous adipose tissue browning in female mice, our recent study found that ERβ functions to protect kidney from progressive renal fibrosis by inactivating transforming growth factor-β (TGF-β)/Smad3 signaling. In the normal kidney, ERβ is highly expressed by proximal tubular epithelial cells but it is lost when kidney becomes fibrotic. In contrast, activation of ERβ inhibits kidney fibrosis. Mechanistically, we uncovered that ERβ can bind to Smad3, thereby transcriptionally downregulating Smad3 and inhibiting TGF-β1/Smad3-mediated renal fibrosis. Thus, ERβ is protective in renal fibrosis and may have therapeutic potential for chronic kidney disease.

Optogenetic-based genetically encoded Ca2+ actuators (GECA) have been developed to enable remote control of Ca2+ entry into cells. However, current blue light-dependent tools either lack high calcium selectivity or exhibit crosstalk with other targets, raising concerns about potential side effects. In this commentary, we present our successful design of a single-component optogenetic Ca2+ ion channel (LOCa) that selectively elevates cytoplasmic Ca2+ concentration with high spatial and temporal resolution. Furthermore, LOCa has demonstrated promising applications in regulating Ca2+-dependent cellular physiological responses and investigating diseases through animal models.

The prognosis of brain metastases in non-small cell lung cancer (NSCLC) is poor, and patients with EGFR mutations are more likely to have brain metastases. The epidermal growth factor receptor (EGFR) gene status has changed the direction of treatment for NSCLC patients with brain metastases. The development of EGFR tyrosine kinase inhibitors (EGFR-TKI) has prolonged the survival time of NSCLC patients with brain metastases. The treatment of patients with NSCLC brain metastases should be individualized according to the clinical symptoms, tumor stage, and different gene mutation status. As cancer is heterogeneous at the molecular level, related biomarker studies looking for individualized characteristics are recommended.

Glioblastoma Multiforme (GBM) is one of the most lethal human cancer types, with a 5-year survival rate of approximately 5%. A key reason for this is usually considered its poor accessibility to systemically administered drugs that only limitedly overcome the Blood Brain Barrier, ultimately causing the likely dismal appearance of recurrences. Here, we comment on our successful use, in GBM preclinical models, of novel thermogel based drug-delivery platforms for loco-regional treatment of tumor recurrences after primary surgery. The innovation as well as the pitfalls of our processes are outlined and discussed with an eye towards potential advancements in the realm of personalized medicine applications.

Testicular adrenal rest tumor (TART) is a long-standing, significant complication of congenital adrenal hyperplasia (CAH). Although it is the main reason for infertility in adult patients with CAH, little is known about the development mechanism, genotype-phenotype features, and exact treatment options of TART. However, in the literature, there are mainly case reports and only a few studies in the pediatric period on this subject. The critical point is the early detection of tumors to prevent infertility in adulthood. This paper reviews the embryological, clinical, diagnostic, genetic features, and treatment alternative of TART and discusses the early screening options.
