- Tubulointerstitial fibrosis is the central pathological feature of hypertensive nephropathy, with cellular senescence being a key driver. Therefore, identifying therapeutic targets in senescent renal tubular epithelial cells is clinically important. The cytoplasmic FMR1-interacting protein (CYFIP) family, which comprises two evolutionarily conserved members, CYFIP1 and CYFIP2, plays crucial roles in neurological regulation. CYFIP2, a key member, is implicated in cytoskeletal dynamics and apoptosis within the nervous system; however, its renal expression pattern and function remain undefined. This study revealed that CYFIP2 expression was significantly upregulated in the renal cortex, particularly in the proximal tubules, of DOCA/salt-induced hypertensive mice, and was positively correlated with the extent of fibrosis. Consistently, CYFIP2 was highly expressed in the renal tubules of patients with hypertensive nephropathy, where its level inversely correlated with the estimated glomerular filtration rate (eGFR). Tubule-specific deletion of CYFIP2 attenuated hypertension-induced cellular senescence (reduced SA-β-gal, p53/p21, and SASP; increased Klotho) and mitigated renal dysfunction, collagen deposition, and epithelial‒mesenchymal transition (EMT). In vitro, CYFIP2 silencing alleviated TGF-β1-induced senescence and fibrosis in HK-2 cells. Mechanistically, CYFIP2 and p53 formed a positive feedback loop that promoted fibrosis by inhibiting the Hippo pathway and enhancing YAP nuclear translocation. The p53 agonist Nutlin-3a reversed the protective effect of CYFIP2 knockout, while the inhibitor Pifithrin-α mimicked this effect. These findings underscore the pivotal role of the CYFIP2/p53-Hippo/YAP axis in hypertensive renal injury, and identify CYFIP2 as a potential therapeutic target. CYFIP2/p53-Hippo signaling drives tubular senescence and renal fibrosis in hypertensive nephropathy. - Source: PubMed

Sun Ming-ChenZuo Fu-WenWang You-ZhaoRen Xiu-LiLu Hong-ShenZheng Ming-BoZhang Hao-RanLiu Han-LinLu Cui-CuiShen Cheng-WuWu Ji-Chao - Microglia are increasingly recognized as key regulators of neural circuit development and putative contributors to the pathophysiology of neuropsychiatric disorders such as schizophrenia (SCZ). However, the functional impact of SCZ-associated genes in microglia remains largely unexplored. Here, we performed an arrayed CRISPR targeting screen of 30 SCZ-associated genes predicted to be differentially expressed in human microglia-like cells. Target genes were prioritized based on post-mortem transcriptomic relevance and predicted ontology-based roles in phagocytosis pathways. We quantified phagocytic activity and morphological changes following gene targeting using high-content confocal imaging. Key targets, including CYFIP1, MSR1, TREM2, SYK, ITGB2, ITGAM, and IRF8, modulated phagocytosis and altered morphological properties consistent with activation states, validating their functional roles in microglia. To elucidate transcriptional impact, we further applied a multiplexed RNA sequencing platform across gene targets. These analyses revealed gene-specific transcriptional signatures, implicating divergent pathways related to phagocytic, activation, cytoskeletal, and lysosomal function. Together, these findings demonstrate the utility of CRISPR-based functional genomics in characterizing microglia function and identifying new target genes and mechanisms that may underlie their contributions to SCZ pathophysiology. - Source: PubMed

Horng Joy EMcCrea Liam TBatorsky Rebecca EBowen Joshua JBoschian CamillaSong YoonjaePerlis Roy HSheridan Steven D - Elucidating the pathophysiological mechanisms of mental disorders remains a critical challenge in psychiatric research. Recent studies have highlighted the potential involvement of cytoskeletal and molecular motor abnormalities in the development of mental disorders such as schizophrenia and autism spectrum disorder (ASD). Although schizophrenia and ASD differ clinically, both disorders are increasingly regarded as neurodevelopmental conditions and share vulnerabilities in synapse formation and neural circuit maturation. This review synthesizes the latest findings on the relationship between cytoskeletal and molecular motor abnormalities and mental disorders. The cytoskeleton, composed of microtubules, actin filaments, and intermediate filaments, along with molecular motors such as kinesins, dyneins, and myosins, plays crucial roles in neurodevelopment, synapse formation, and neurotransmission. In schizophrenia, decreased expression of the microtubule-associated protein MAP2 and abnormalities in the DISC1 gene have been reported, potentially leading to dendritic morphological abnormalities and neurodevelopmental disorders. Additionally, abnormalities in molecular motors such as KIF17 and KIF1A have been implicated in schizophrenia pathophysiology. Myosin Id has been identified as a risk gene for ASD. Furthermore, abnormalities in actin-related proteins such as SHANK3 and CYFIP1 have been shown to cause synaptic dysfunction. These findings suggest that mental disorders arise from complex pathologies involving multiple cytoskeletal and molecular motor-related protein abnormalities. Future research should focus on elucidating the functions of individual proteins and adopting a comprehensive approach that includes glial cells. Advances in this field may deepen our understanding of the pathophysiological mechanisms of mental disorders and potentially lead to the development of novel therapeutic strategies. - Source: PubMed

Nakamura KenyuKubo AsumiSanaka SaeKamiya SaraItagaki KentaroSasaki Tetsuya - Chromosome region 15q11-q13 is prone to structural rearrangements and contains imprinted genes associated with several neurodevelopmental syndromes. In this report, we present the case of a 518 kb duplication in 15q11.2, identified prenatally through array comparative genomic hybridization. Parental testing revealed that the duplication was paternally inherited and originated from the asymptomatic paternal grandmother. The duplicated region harbored the OMIM genes , , , and , all of which presented biallelic expression and were not subjected to genomic imprinting. Given the benign familial inheritance and lack of clinical features in the father and the paternal grandmother, the duplication was considered likely to have benign significance. A healthy female newborn was delivered at term. - Source: PubMed

Despite emerging evidence that microglial motility plays important roles in brain development, neurodegeneration, and neuropsychiatric disease, little is known about the intracellular machinery orchestrating microglial process dynamics. Here, we identify roles for regulators of the actin cytoskeleton in controlling microglial behavior. We show that the actin branching Arp2/3 complex is critical for maintaining microglial morphology and is required for surveillance but not chemotactic motility. Neuropsychiatric disease-associated CYFIP1, a core component of the WAVE regulatory complex linking upstream signaling pathways to activation of the Arp2/3 complex, is highly expressed in microglia but has an unknown function. We report that conditional deletion of in mouse microglia reduces their morphological complexity and surveillance of the brain parenchyma, with no effect on chemotaxis. Deletion of also increased microglial CD68 positive lysosome volume and engulfment of presynapses. Thus, actin remodeling by CYFIP1 and the Arp2/3 complex controls microglial dynamics and shifts microglia away from a homeostatic state with potential implications for neuropsychiatric disease. - Source: PubMed
