Steroidogenic acute regulatory protein (StAR) plays a critical role in the regulation of progesterone (P4) production. Resveratrol (RSV), a natural polyphenol, has beneficial effects on reproductive function. However, its effects on StAR expression and P4 production in human granulosa cells remain undetermined. In this study, we showed that treatment of RSV upregulated StAR expression in human granulosa cells. G protein-coupled estrogen receptor (GPER) and ERK1/2 signaling were involved in RSV-stimulated StAR expression and P4 production. In addition, the expression of a transcriptional repressor, Snail, was downregulated by RSV, which contributed to the RSV-induced inductions of StAR expression and P4 production.

Background: Endocrine-disrupting chemicals (EDCs) interfere with the endocrine system and negatively impact reproductive health. Biochanin A (BCA), an isoflavone with anti-inflammatory and estrogen-like properties, has been identified as one such EDC. This study investigates the effects of BCA on transcription, metabolism, and hormone regulation in primary human granulosa cells (GCs), with a specific focus on the activation of bitter taste receptors (TAS2Rs).

Background: Vocal fold leukoplakia (VFL), a precancerous lesion of the larynx, is characterized by white plaques on the vocal fold mucous membrane. Currently, there are no reliable biomarkers to predict the recurrence and malignant transformation of VFL. Considering chondroitin sulfate proteoglycan 4 (CSPG4) as a biomarker for malignant tumors such as laryngeal squamous cell carcinoma (LSCC), we conducted this cohort study to evaluate the prognostic influence of CSPG4 expression on VFL patients.

The biosynthesis of isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP), which are essential for sesquiterpenes and triterpenes, respectively, is primarily governed by the mevalonate pathway, wherein () plays a pivotal role. This study identified eight members of the FPS gene family in , designated -, through bioinformatics analysis, revealing their distribution across several chromosomes and a notable tandem gene cluster. The genes exhibited strong hydrophilic properties and key functional motifs crucial for enzyme activity.

Reduced expression of nucleolar genes induces stress and DNA damage. Here, we present a protocol to analyze DNA fragmentation at the single-cell level in Drosophila imaginal discs using an optimized alkaline comet assay. We describe steps for larvae development, tissue disaggregation, and single-cell dissociation.

Background: The expression of anti-programmed cell death ligand-1 (PD-L1) in tumors is widely used as a biomarker to predict the therapeutic efficacy of anti-programmed cell death-1(PD-1)/PD-L1 antibodies. However, the predictive accuracy of this method is limited. High-mobility group box 1 (HMGB1) is known to modulate cancer immunity.
