- Spermatogonial stem cells (SSCs) are unipotent germline cells with emerging pluripotent potential under specific in vitro conditions. Understanding their capacity for reprogramming and the molecular mechanisms involved offers valuable insights into regenerative medicine and fertility preservation. SSCs were isolated from Oct4-GFP C57BL/6 transgenic mice using enzymatic digestion and cultured in defined media. Under these conditions, ES-like colonies emerged expressing pluripotency markers. These cells were characterized by immunocytochemistry, teratoma assays, and transcriptomic analyses using bulk and single-cell RNA sequencing datasets. Gene expression profiles were compared with ESCs and SSCs using datasets from GEO (GSE43850, GSE38776, GSE149512). Protein-protein interaction (PPI) networks and co-expression modules were explored through STRING, Cytoscape, and WGCNA. ES-like cells derived from SSCs exhibited strong expression of OCT4, DAZL, and VASA. Transcriptomic analysis revealed key differentially expressed genes and shared regulatory networks with ESCs. WGCNA identified key co-expression modules and hub regulatory RNA binding genes (Ctdsp1, Rest, and Stra8) potentially responsible for the reprogramming process. Teratoma assays confirmed pluripotency, and single-cell RNA-seq validated expression of critical markers in cultured SSCs. This study demonstrates that SSCs can acquire pluripotency features and be reprogrammed into ES-like cells. The integration of transcriptomic and network-based analyses reveals novel insights into the molecular drivers of SSC reprogramming, highlighting their potential utility in stem cell-based therapies and male fertility preservation. - Source: PubMed

Shakeri Abroudi AliAzizi HosseinKhalid Abdullah HewaAlsaffar Marwa FadhilSkutella Thomas - Amino acids and ammonia serve as sources of nitrogen for cell growth and were previously thought to have similar effects on yeast. Consistent with this idea, depletion of either of these two nitrogen sources inhibits the target of rapamycin complex 1 (TORC1), leading to induction of macroautophagy/autophagy and inhibition of cell growth. In this study, we show that Whi2 and the haloacid dehalogenase (HAD)-type phosphatases Psr1 and Psr2 distinguish between these two nitrogen sources in , as the Whi2-Psr1-Psr2 complex inhibits TORC1 in response to low leucine but not in the absence of nitrogen. In contrast, a parallel pathway controlled by Npr2 and Npr3, components of the Seh1-associated complex inhibiting TORC1 (SEACIT), suppress TORC1 under both low leucine- and nitrogen-depletion conditions. Co-immunoprecipitations with mutants of Whi2, Psr1, Psr2 and fragments of Tor1 support the model that Whi2 recruits Psr1 and Psr2 to TORC1. In accordance, the interaction between Whi2 and Tor1 appears to increase under low leucine but decreases under nitrogen-depletion conditions. Although the targets of Psr1 and Psr2 phosphatases are not known, mutation of their active sites abolishes their inhibitory effects on TORC1. Consistent with the conservation of HAD phosphatases across species, human HAD phosphatases CTDSP1 (CTD small phosphatase 1), CTDSP2, and CTDSPL can functionally replace Psr1 and Psr2 in yeast, restoring TORC1 inhibition and autophagy activation in response to low leucine conditions. - Source: PubMed

In 2019, Sekine et al. demonstrated the presence of YAP1::MAML2 and YAP1::NUTM1 fusions in most poromas and porocarcinomas. Recently, our group identified PAK2-fusions in a subset of benign poromas. Herein we report a series of 12 porocarcinoma cases harbouring PAK1/2/3 fusions. - Source: PubMed

Small C-terminal domain phosphatases CTDSP1, CTDSP2, and CTDSPL (also known as SCP1, 2, 3) are involved in the regulation of several important pathways associated with carcinogenesis. In various cancer types, these phosphatases may demonstrate either antitumor or oncogenic activity. Tumor-suppressive activity of these phosphatases in kidney cancer has been shown previously, but in general case, the antitumor activity may be dependent on the choice of cell line. In the present work, transfection of the Caki-1 cell line (ccRCC morphologic phenotype) with expression constructs containing the coding regions of these genes resulted in inhibition of cell growth in vitro in the case of ( < 0.001) and ( < 0.05) but not . The analysis of The Cancer Genome Atlas (TCGA) data showed differential expression of some of genes and of their target, . These results were confirmed by quantitative RT-PCR using an independent sample of primary ccRCC tumors ( = 52). We observed downregulation and found a positive correlation of expression for two gene pairs: and ( = 0.76; < 0.001) and and ( = 0.38; < 0.05). Survival analysis based on TCGA data demonstrated a strong association of lower expression of , , , and with poor survival of ccRCC patients ( < 0.001). In addition, according to TCGA, , , and were differently expressed in two subtypes of ccRCC-ccA and ccB, characterized by different survival rates. These results confirm that and have tumor suppressor properties in ccRCC and reflect their association with the more aggressive ccRCC phenotype. - Source: PubMed

Krasnov George SPuzanov Grigory ADashinimaev Erdem BVishnyakova Khava SKondratieva Tatiana TChegodaev Yegor SPostnov Anton YSenchenko Vera NYegorov Yegor E - Elabela (ELA), which is the second endogenous peptide ligand of the apelin receptor (APJ) to be discovered, has been widely studied for potential use as a therapeutic peptide. However, its role in ischemic stroke (IS), which is a leading cause of disability and death worldwide and has limited therapeutic options, is uncertain. The aim of the present study was to investigate the beneficial effects of ELA on neuron survival after ischemia and the underlying molecular mechanisms. Primary cortical neurons were isolated from the cerebral cortex of pregnant C57BL/6J mice. Flow cytometry and immunofluorescence showed that ELA inhibited oxygen-glucose deprivation (OGD) -induced apoptosis and axonal damage in vitro. Additionally, analysis of the Gene Expression Omnibus database revealed that the expression of microRNA-124-3p (miR-124-3p) was decreased in blood samples from patients with IS, while the expression of C-terminal domain small phosphatase 1 (CTDSP1) was increased. These results indicated that miR-124-3p and CTDSP1 were related to ischemic stroke, and there might be a negative regulatory relationship between them. Then, we found that ELA significantly elevated miR-124-3p expression, suppressed CTDSP1 expression, and increased p-AKT expression by binding to the APJ receptor under OGD in vitro. A dual-luciferase reporter assay confirmed that CTDSP1 was a direct target of miR-124-3p. Furthermore, adenovirus-mediated overexpression of CTDSP1 exacerbated neuronal apoptosis and axonal damage and suppressed AKT phosphorylation, while treatment with ELA or miR-124-3p mimics reversed these effects. In conclusion, these results indicated that ELA could alleviate neuronal apoptosis and axonal damage by upregulating miR-124-3p and activating the CTDSP1/AKT signaling pathway. This study, for the first time, verified the protective effect of ELA against neuronal injury after ischemia and revealed the underlying mechanisms. We demonstrated the potential for the use of ELA as a therapeutic agent in the treatment of ischemic stroke. - Source: PubMed
