In conclusion, DES affects the morphology and alters the gubernaculum structure, as well as the expression of RXFP2 protein. These data demonstrate that DES is toxic to gubernaculum in fetal mice, and that RXFP2 is associated with the abnormal gubernaculum morphology induced by DES. Taken together, these data suggest that RXFP2 may be a novel potential biomarker for abnormal differentiation of the gubernaculum.Gemcitabine is widely used as an anticancer chemotherapy drug for a variety of solid tumors, and it has become the standard treatment option for locally advanced and metastatic pancreatic cancer. However, pancreatic cancer cells develop resistance to gemcitabine after a few weeks of treatment, resulting in poor therapeutic effects. Isocorydine (ICD) is a typical natural aporphine alkaloid, and ICD and its derivatives inhibit the proliferation of many types of cancer cells in vitro. In this study, ICD was found to synergistically inhibit cell viability with gemcitabine in pancreatic cancer cells. A microarray analysis showed that ICD can inhibit the upregulation of STAT3 and EMT in pancreatic cancer cells induced by gemcitabine. STAT3 is closely related to tumor EMT, migration and invasion. After knocking down the expression of STAT3 in pancreatic cancer cells, the combination index (CI) of ICD and gemcitabine decreased. ICD can reverse the increase in the expression of EMT-related transcription factors and proteins caused by gemcitabine, thereby inhibiting the enhanced cell migration and invasion ability caused by gemcitabine. Finally, the synergistic treatment effect of the combination treatment of ICD and gemcitabine in pancreatic cancer cells was confirmed in established xenograft models.Poor sensitivity to chemotherapy drugs and high recurrence rates are the bottlenecks to successful chondrosarcoma treatment. Notably, niclosamide has been identified as a potential anti-cancer agent. To investigate the effects and mechanisms of niclosamide in the context of human chondrosarcoma treatment, SW1353 and CAL78 human chondrosarcoma cells were treated with various concentrations of niclosamide. The CKK-8 assay was performed to quantify cell viability. Cell proliferation was determined with crystal violet staining and colony forming assays. TUNEL and annexin V-FITC flow cytometry assays were performed to detect cell apoptosis. Wound healing and Transwell assays were conducted to evaluate migratory and invasive cell behaviors. The effect of niclosamide on the mitochondria was evaluated with the JC-1 and Seahorse Cell Mito Stress Assays. The expression of caspase-3, cleaved caspase-3, caspase-9, cleaved caspase-9, and β-tubulin levels were investigated by western blotting. Collectively, the data demonstrated that niclosamide inhibited cell growth and proliferation, attenuated migratory and invasive cell behaviors, and promoted apoptosis. Niclosamide is as a potent chondrosarcoma tumor inhibitor that activates the caspase-dependent mitochondrial apoptotic pathway and could be a novel therapeutic approach to treat chondrosarcoma.Noise pollution is a major public hazard. Previous studies have shown that environmental noise affects the reorganization of the auditory cortex and leads to behavioral abnormality; however, the effects of long-term environmental noise exposure on the inner ear and hearing remain to be elucidated. In this study, we simulated environmental noise with a long-term 70 dB sound pressure level "white" noise, observed its effect on the inner ears of C57BL/6J mice, and developed an in vitro model for mechanistic studies. We found that environmental noise increased the hearing threshold, decreased the auditory response amplitude, and aggravated the range and extent of age-related hearing loss (ARHL), especially in the intermediate frequency band in mice. Cochlear ribbon synapse is the primary site of inner ear injury caused by environmental noise. We also verified, through an in vitro simulation of the excitatory toxicity of glutamate and aging effects, that the activation of NLRP3 inflammasome plays a vital role in the cochlear ribbon synaptic damage. Our results show that long-term exposure to low-intensity environmental noise can lead to hearing loss via the disruption of ribbon synapses, which is caused by an inflammatory reaction. Additionally, environmental noise can further aggravate the progression of ARHL. This study expounded the pathogenesis of the inner ear damage caused by environmental noise exposure and provides a new direction for the prevention and treatment of hearing loss.
Polycystic ovary syndrome (PCOS) is associated with alteration of Apelin signaling in ovarian granulosa cells (GCs). However, the molecular mechanisms regulating Apelin expression remain poorly understood. This study aims to investigate the role of miR-424 in modulating Apelin expression and GC functions.

miRNA expression in GCs was altered by transfection with specific miR-424 mimics and inhibitors. Apelin level was determined by ELISA. miR-424 and mRNA expression were analyzed by quantitative RT-PCR. Protein abundance was measured by western blotting. Genomic sequence targeted by miR-424 was validated by dual-luciferase reporter assay. Apelin gene was overexpressed by transfection of LV-003 vector carrying its cDNA. GC proliferation was analyzed by MTS method, and its cell cycle progression and apoptosis were measured by flow cytometry.

Apelin concentration was increased in serum and follicular fluid from PCOS patients, accompanied by upregulated APJ (Apelin receptor) expression and suppressed miR-424 expression in GCs. AZD9291 molecular weight miR-424 mimics suppressed Apelin and APJ expression in KGN cells by targeting 3' UTR of Apelin and APJ, whereas miR-424 inhibitors had the opposite effects. miR-424 inhibited KGN cell proliferation and cell cycle progression by down-regulating Cyclin-D/E expression. Moreover, miR-424 promoted KGN cell apoptosis by increasing truncated Caspase-3 level. The regulation of KGN cell proliferation and apoptosis by miR-424 was mediated by directly suppressing Apelin gene expression, instead of inhibiting Apelin peptide activity.

miR-424 suppresses proliferation and promotes apoptosis of human ovarian granulosa cells by directly targeting and inhibiting Apelin and APJ expression.
