Summary: The study utilized CRISPR/Cas9 technology to investigate the role of Rai14 in mouse testis, indicating that Rai14 is dispensable for mouse spermatogenesis and fertility. In contrast to previous results in rat models, Rai14 knockout in mice did not significantly affect sperm parameters and cellular apoptosis. The findings provide enhanced understanding of Rai14's role in the testis and may prevent redundant experiments.

Summary: Sertoli cells provide a nurturing environment for germ cell development and maturation, and the role of phosphatidylinositol 3-kinase (PtdIns3K) in Sertoli cells is unclear. Deleting the Pik3c3 gene specifically in Sertoli cells resulted in infertility, disrupted Sertoli cell polarity, and impaired spermiogenesis. Accumulation of SCIN caused the disorganization of the F-actin cytoskeleton, while accumulated HDAC6 deacetylated SCIN, leading to a disorganized F-actin cytoskeleton.

Summary: The study revealed that BP-3 exhibited toxicity on Sertoli cells by altering cell morphology, reducing cell viability, and disrupting the integrity of the Sertoli cell barrier. Additionally, BP-3 could perturb Sertoli cell functions through affecting junction proteins and F-actin organization, but did not induce cell apoptosis.

Summary: This review summarizes recent findings on the role of Kinesin in mammalian spermatogenesis, highlighting its potential role in germ cell traversal through the blood-testis barrier and the remodeling of Sertoli cell-spermatid junctions to advance spermatid transport. The possibility of Kinesin acting as a mediator and/or synchronizer for cell cycle progression, germ cell transit, and junctional rearrangement and turnover is also discussed.

Summary: Sertoli cells contribute to the formation of the blood-testis barrier (BTB) during spermatogenesis. MicroRNA-181c/d (miR-181c/d) regulates Sertoli cell survival and barrier function by targeting the Pafah1b1 gene and inhibiting the CDC42/PAK1/LIMK1/Cofilin pathway. Excessive expression of miR-181c/d perturbs BTB function and Sertoli cell proliferation but disappears after a few weeks.

Summary: The evolutionarily conserved coronin family protein POD-1 debranches Arp2/3-nucleated actin filaments in migrating neuroblasts and asymmetrically dividing embryos, contributing to cell polarity and migration. Fluorescence live imaging analysis revealed POD-1 colocalization with Arp2/3 at the leading edge of neuroblasts, indicating their synergistic role in organizing actin networks and cell polarity. Conditional mutations of POD-1 disrupted actin assembly, cell polarity, and migration, highlighting the importance of F-actin debranching in regulating these cellular processes.

Summary: The actin cytoskeleton contributes to various cellular processes and actin-depolymerizing factor (ADF) is an important regulator of actin filament dynamics. This study investigates the role of HbADF4 in regulating actin dynamics in latex flow in rubber tree. The downregulation of HbADF4 resulted in an increase in the F/G-actin ratio in latex, while upregulation caused a decrease in the ratio. HbADF4 is also associated with stress and hormone responses in rubber tree and plays a role in cytokinesis and cell elongation.

Summary: Net1, an overexpressed gene in various cancers, plays a crucial role in cancer cell motility and proliferation, as well as mitotic progression. The mitotic kinase Cdk1 phosphorylates Net1 at multiple sites, negatively regulating its ability to signal to RhoA and alter actin cytoskeletal organization. The study also showed that inhibition of Cdk1 increased Net1 activity and affected its localization to the plasma membrane and cortical F-actin accumulation.

Summary: Epilepsy is a chronic neurological disorder associated with impaired neurodevelopment and immunity. The chemokine receptor CXCR5 plays a role in seizures through an unknown mechanism. This study found that knockdown of CXCR5 increases susceptibility to seizures in mice, while overexpression has the opposite effect. CXCR5 deficiency disrupts neuronal migration and polarization, leading to increased neuronal hyperexcitability and seizure-related electrical activity.

Summary: Premitotic control of cell division orientation is critical for plant development, with formative divisions often producing daughters with different fates. Auxin-dependent division plane control involves alterations in cell geometry by regulating genes controlling cell wall and cytoskeleton properties. This interaction with cell geometry generates asymmetric divisions during the earliest steps in plant development.

Summary: Inversin is a component of the Frizzled/Dishevelled/Diversin planar cell polarity complex that plays a crucial role in tissue and organ development. Recent studies have also shown its involvement in supporting spermatogenesis in adult rat testes. This research focuses on investigating the role of inversin in Sertoli cell and testis function using RNA interference. The results demonstrate that by altering the organization of the cytoskeleton, inversin affects the barrier function of Sertoli cells and results in defects in spermatogenesis.

Summary: The study focused on the presence and sources of intracellular and extracellular antibiotic resistance genes in chlorinated drinking water distribution systems, revealing that the eARG concentration decreased while the proportion of vanA and blaNDM-1 increased. Additionally, the diversity of the eDNA-releasing community increased with distance from the water treatment plant, and the dominant eDNA-releasing bacteria changed along the distribution system. Conversely, the concentration of intracellular ARGs increased, while the biodiversity of the planktonic bacteria community decreased along the distribution system. The findings provide important insights into the spatial behavior and sources of eARGs, highlighting health risks associated with ARGs in drinking water distribution systems.

Summary: Four-jointed box kinase 1 (Fjx1) is a Golgi-based regulator of Fat1 function by phosphorylating Fat1 at its extracellular cadherin domains. It localizes across the Sertoli cell cytoplasm and partially co-localizes with microtubules. Fjx1 knockdown perturbs Sertoli cell tight junction function, MT and actin organization, and regulates the expression of Fat1 and Dchs1.
