Article Abstract
Global population aging is one of the major social and economic challenges of contemporary society. During aging the progressive decline in physiological functions has serious consequences for all organs including brain. The age-related incidence of neurodegenerative diseases coincides with the sharp decline of the amount and functionality of adult neural stem cells. Recently, we identified a short list of brain age-regulated genes by means of next-generation sequencing. Among them znf367 codes for a transcription factor that represents a central node in gene co-regulation networks during aging, but whose function in the central nervous system (CNS), is completely unknown. As proof of concept, we analysed the role of znf367 during Xenopus laevis neurogenesis. By means of a gene loss of function approach limited to the CNS, we suggested that znf367 might act as a key controller of the neuroblast cell cycle, particularly in the progression of mitosis and spindle checkpoint. A candidate gene approach based on a weighted-gene co-expression network analysis, revealed fancd2 and ska3 as possible targets of znf367. The age-related decline of znf367 correlated well with its role during embryonic neurogenesis, opening new lines of investigation also in adult neurogenesis to improved maintenance and even repair of neuronal function.

Thyroid hormone promotes fetal neurogenesis.

Maternal low thyroxine (T4) serum levels during the first trimester of pregnancy correlate with cerebral cortex volume and mental development of the progeny, but why neural cells during early fetal brain development are vulnerable to maternal T4 levels remains unknown. In this study, using iPSCs obtained from a boy with a loss-of-function mutation in MCT8-a transporter previously identified as critical for thyroid hormone uptake and action in neural cells-we demonstrate that thyroid hormones induce transcriptional changes that promote the progression of human neural precursor cells along the dorsal projection trajectory. Consistent with these findings, single-cell, spatial, and bulk transcriptomics from MCT8-deficient cerebral organoids and cultures of human neural precursor cells underscore the necessity for optimal thyroid hormone levels for these cells to differentiate into neurons.

Apical-basal polarity (ABP) establishment and maintenance is necessary for proper brain development, yet how it is controlled is unclear. Galectin-3 (Gal-3) has been previously implicated in ABP of epithelial cells, and, here, we find that it is apically expressed in human embryonic stem cells (hESCs) during neural induction. Gal-3 blockade disrupts ABP and alters the distribution of junctional proteins in hESC-derived neural rosettes and is rescued by addition of recombinant Gal-3.

As a gynecological disease, endometriosis is a disease in which pain and inflammation are important parts. Endometriosis is a chronic, estrogen-related situation with a multifactorial etiology that remains incompletely understood. Endometriosis affects approximately 6-10% of females and is a prominent reason of infertility.

Recent advances in neural differentiation have unveiled new possibilities that could potentially be applied to the development of human-relevant non-animal models, for use in fields such as biomedical research and drug screening. Thus, the directed differentiation of tissue stem cells toward neural progenitor cells or neural stem cells, by small molecules and growth factors without the need for genetic manipulation, has attracted great attention. The generation of neural progenitor cells, and their proliferation and lineage commitment are regulated by signaling pathways activated by small molecules and growth factor families, including various fibroblast growth factors (FGFs).

An important disadvantage of plastics is their fragmentation into smaller particles, classified according to size as microplastics and nanoplastics. These plastic particles persist for extended periods in aerial, terrestrial, and aquatic ecosystems and can be incorporated into animal bodies through various routes, including inhalation, dermal contact, and the food chain. The accumulation of these debris generates toxicity on several organs, including the nervous system.
