Understanding Genetic Regulation of Sex Differentiation in Hermaphroditic Fish

Animals, Journal Year: 2025, Volume and Issue: 15(2), P. 119 - 119

As a fundamental taxonomic group within vertebrates, fish represent an invaluable resource for investigating the mechanisms underlying sex determination and differentiation owing to their extensive geographical distribution rich biodiversity. Within this biological cohort, processes of are intricately governed by both genetic factors complex interplay environmental cues. While variations in external factors, particularly temperature, can exert modulatory influence on limited degree, remain primary determinants sexual traits. Hermaphroditic display three distinct types transitions: protandry (male female), protogyny (female-to-male), bidirectional change (both directions serially). These fish, characterized unique reproductive strategies plasticity, serve as exemplary natural models elucidating transitions fish. The present review delves into histological dynamics during gonadal development across sequential hermaphroditic meticulously delineating pivotal characteristics at each stage, from inception primordial gonads specialization. Furthermore, it examines regulatory genes associated signaling pathways that orchestrate differentiation. By systematically synthesizing these research advancements, paper endeavors offer comprehensive profound insight intricate governing

The Effects of Acute Temperature Changes on Transcriptomic Responses in the Liver of Leopard Coral Groupers (Plectropomus leopardus)

Antioxidants, Journal Year: 2025, Volume and Issue: 14(2), P. 223 - 223

The leopard coral grouper (Plectropomus leopardus) is a commercially significant tropical marine species. With the ongoing effects of global climate change, increasing attention has been focused on grouper's susceptibility to extreme cold weather. This study investigates acute exposure and temperature recovery liver P. leopardus. Histological observations enzyme activity assays revealed that fluctuations caused disruptions normal physiology, including lipid accumulation alterations in antioxidant levels. Transcriptomic analysis tissue identified 2744 differentially expressed genes (DEGs) across three experimental groups: 25 °C (control), 13 (cold exposure), rewarming at (R-25 °C). Functional enrichment these DEGs were significantly associated with biological processes such as metabolism defense, well pathways related metabolism, fatty acid biosynthesis, ferroptosis. Furthermore, dynamic regulation immune responses, oxidative stress was observed response both rewarming. Notably, several redox-related identified, their interactions further explored. Additionally, representative antioxidants got1, gpx1a, gpt, g6pcla.2, validated by qRT-PCR fluorescence situ hybridization (FISH). Taken together, this provides systematic grouper, laying groundwork for research responses teleost
