Animals determine their sex genetically (GSD: genetic sex determination) and/or environmentally (ESD: environmental sex determination). Medaka (Oryzias latipes) employ a XX/XY GSD system, however, they display female-to-male sex reversal in response to various environmental changes such as temperature, hypoxia, and green light. Interestingly, we found that 5 days of starvation during sex differentiation caused female-to-male sex reversal. In this situation, the metabolism of pantothenate and fatty acid synthesis plays an important role in sex reversal. Metabolism is associated with other biological factors such as germ cells, HPG axis, lipids, and epigenetics, and supplys substances and acts as signal transducers. In this review, we discuss the importance of metabolism during sex differentiation and how metabolism contributes to sex differentiation.

Na⁺/H⁺ exchanger regulatory factor 2 (NHERF2) is a nucleocytoplasmic protein initially identified as a regulator of membrane-bound sodium-hydrogen exchanger 3 (NHE3). In the cytoplasm, NHERF2 regulates the activity of G protein-coupled receptors (GPCRs), including beta-2 adrenergic receptor (2β-AR), lysophosphatidic acid receptor 2, and parathyroid hormone type 1 receptor. In the nucleus, NHERF2 acts as a coregulator of transcription factors such as sex-determining region Y protein (SRY), involved in male sex determination, and estrogen receptor alpha (ERα).

Hypospadias, a common congenital anomaly of male genitalia, shows significant heritability and familial recurrence, particularly in consanguineous families. This study explored the role of KMT2C polymorphisms in a Yemeni family with two affected siblings. Comprehensive analysis identified 475 unique SNPs in KMT2C, with 59 shared between parents, suggesting common ancestry.

Myoepithelial tumours are rare and distinct entities with uncertain histogenesis. They occur primarily in major salivary glands and soft tissue around the head and neck. Bony involvement predominantly occurs in facial bones.

Neuroinflammation and mitochondrial dysfunction are early events in Alzheimer's disease (AD) and contribute to neurodegeneration and cognitive impairment. Evidence suggests that the inflammatory axis mediated by macrophage migration inhibitory factor (MIF) binding to its receptor, CD74, plays an important role in many central nervous system (CNS) disorders such as AD. Our group has developed DRhQ, a novel CD74 binding construct which competitively inhibits MIF binding, blocks macrophage activation and migration into the CNS, enhances anti-inflammatory microglia cell numbers and reduces pro-inflammatory gene expression.

This study explored the structural relationships among family of origin health, self-differentiation, mentalization, and marital satisfaction, focusing on indirect effects and gender differences. Data from 400 married Korean adults aged 30-49 were analyzed using structural equation modeling and multigroup analysis. Results revealed that all paths were significant except the direct impact of family-of-origin health on marital satisfaction.
