Unveiling the role of miRNAs in Diminished Ovarian Reserve: an in silico network approach.

MicroRNAs (miRNAs) have acquired an increased recognition to unravel the complex molecular mechanisms underlying Diminished Ovarian Reserve (DOR), one of the main responsible for infertility. To investigate the impact of miRNA profiles in granulosa cells and follicular fluid, crucial players in follicle development, this study employed a computational network theory approach to reconstruct potential pathways regulated by miRNAs in granulosa cells and follicular fluid of women suffering from DOR. Available data from published research were collected to create the FGC_MiRNome_MC, a representation of miRNA target genes and their interactions.

The prevalence of goiter, thyroid nodules, and thyroid cancers in the pediatric population has increased. In some rare cases, local conditions such as juvenile desmoid-type fibromatosis (JDTF) can mimic specific thyroid pathology, complicating the diagnostic process. A 17-year-old obese adolescent girl was admitted to the Endocrinology Department with progressive swelling on the left side of the neck, persisting for approximately one year, recently accompanied by dysphonia and inspiratory dyspnea, and ultimately diagnosed as a unilateral nodular goiter associated with compressive phenomena.

Background/objectives: The avascular nature of the follicle creates a hypoxic microenvironment, establishing a niche where granulosa cells (GCs) rely on glycolysis to produce energy in the form of lactate (L-lactate). Autophagy, an evolutionarily conserved stress-response process, involves the formation of autophagosomes to encapsulate intracellular components, delivering them to lysosomes for degradation. This process plays a critical role in maintaining optimal follicular development.

Endosomal toll-like receptors (TLRs) TLR7, TLR8, and TLR9 play an important role in systemic lupus erythematosus (SLE) pathogenesis. The proteolytic processing of these receptors in the endolysosome is required for signaling in response to DNA and single-stranded RNA, respectively. Targeting this proteolytic processing may represent a novel strategy to inhibit TLR-mediated pathogenesis.

Studies have demonstrated significant alterations in ovarian oxidative stress levels, ovarian degeneration, and follicular atresia during the broody period in geese. The results of this study showed that during the broody period, geese exhibited degraded ovarian tissues, disrupted follicular development, a thinner granulosa cell layer, and lower levels of ovarian hormones E2, P4, and AMH. Antioxidant activity (GSH, CAT, SOD, T-AOC, and the content of HO) and the mRNA expression levels of antioxidant genes (GPX, SOD-1, SOD-2, CAT, COX-2, and Hsp70) were significantly higher in pre-broody geese compared to laying geese, while the expression of apoptosis-related genes (p53, Caspase-3, and Caspase-9) increased and the anti-apoptotic gene Bcl-2 decreased.
