Live-imaging is an essential tool to visualize live cells and monitor their behaviors during development. This technology demands a variety of mouse reporter lines, each uniquely expressing a fluorescent protein. Here, we developed an R26R-RG reporter mouse line that conditionally and simultaneously expresses mCherry and EGFP in nuclei and plasma membranes, respectively, from the Rosa26 locus. The intensity and resolution of mCherry nuclear localization and EGFP membrane localization were demonstrated to be sufficient for live-imaging with embryos that express RG (mCherry and EGFP) ubiquitously and specifically in fetal Sertoli cells. The conditional R26R-RG reporter mouse line should be a useful tool for labeling nuclei and membranes simultaneously in distinct cell populations.

Background: Exosomes derived from cancer-associated fibroblasts (CAFs) can affect tumor microenvironment (TME) of thyroid cancer (TC). The cAMP response element binding protein 1 (CREB1) acts as a transcription factor to participate in cancer development. Currently, we aimed to explore the molecular mechanism of exosome-associated CREB1 and C-C motif chemokine ligand 20 (CCL20) in TC.

Background: Although recent progress provides mechanistic insights into diabetic nephropathy (DN), effective treatments remain scarce. DN, characterized by proteinuria and a progressive decline in renal function, primarily arises from podocyte injury, which impairs the glomerular filtration barrier. Wogonoside, a bioactive compound from the traditional Chinese herb Scutellaria baicalensis, has not been explored for its role in DN.

Background: Ovarian cancer (OC) progression is one of the commonest cause of female cancer death. While treatments in clinic includes primary surgery and targeted chemotherapy, curative and survival trends in OC have not significantly improved. Thus, further investigation of the mechanisms regarding OC carcinogenesis and discovery of novel targets is of great importance.

Background: Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder among women of reproductive age. It is characterized by hyperandrogenism, ovulatory dysfunction, and the presence of polycystic ovarian morphology (PCOM) on ultrasound, often accompanied by metabolic disturbances such as insulin resistance and obesity. Current treatments, including oral contraceptives and anti-androgen medications, often yield limited efficacy and undesirable side effects.

Background: Metastasis is a leading cause of cancer-related death in castration-resistant prostate cancer (CRPC) patients. Circular RNAs (circRNAs) have emerged as key regulators of the metastasis of various cancers. However, the functional effects and regulatory mechanisms of circRNAs in metastatic CRPC (mCRPC) remain largely unknown.
