The morbidity and mortality of NSCLC remains high worldwide. However, the molecular mechanisms of NSCLC still largely unclear. Ets variant 5 (ETV5) is a transcription factor that found to be overexpressed in multiple cancers. However, the role of ETV5 in NSCLC remains unknown. We aim to explore the role and mechanisms of ETV5 in NSCLC development. The expression of ETV5 was evaluated in NSCLC tissues and cell lines. ETV5 overexpressing and downregulation cell lines were established according to the endogenous expression of ETV5. Functional studies were performed by transwell assay. The downstream targets of ETV5 were screened by PCR array and were confirmed by luciferase reporter assay. We found that overexpression of ETV5 indicates worse prognosis of NSCLC patients. Elevated ETV5 expression promotes NSCLC cell invasion and migration via transcriptional activates of TGFβ1. Therefore, ETV5/TGFβ signaling may serve as a therapeutic target for NSCLS patients.

Polyomavirus enhancer activator 3 (PEA3), an ETS transcription factor, has been documented to regulate the development and metastasis of human cancers. Nonetheless, a thorough analysis examining the relationship between the PEA3 subfamily members and tumour development, prognosis, and the tumour microenvironment (TME) across various cancer types has not yet been conducted. The expression profiles and prognostic significance of the PEA3 subfamily were evaluated using data from the GEO, TCGA, and PrognoScan databases, in conjunction with COX regression analyses and the Kaplan-Meier Plotter.

Reversible transformation of bovine leukocytes by the intracellular parasites Theileria annulata and Theileria parva is central to pathogenesis of the diseases they cause, tropical theileriosis and East Coast Fever, respectively. Parasite-dependent constitutive activation of major host transcription factors such as AP-1 (Activating Protein 1) and NF-κB (Nuclear Factor-Kappa B) sustains the transformed state. Although parasite interaction with host cell signaling pathways upstream of AP-1 have been studied, the precise contribution of Theileria encoded factors capable of modulating AP-1 transcriptional activity, and other infection-altered signaling pathways is not fully understood.

Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1), is a long non-coding RNA localized in the cell nucleus, known for its multifunctional roles, including potential involvement in spermatogenesis. This study investigates the mechanism by which MALAT1 dysregulation contributes to the pathogenesis of idiopathic non-obstructive azoospermia (iNOA). We analyzed MALAT1 levels in two gene expression profiling datasets comprising patients with obstructive azoospermia (OA) who have normal spermatogenesis and 13 patients with iNOA.

During thymic development, most γδ T cells acquire innate-like characteristics that are critical for their function in tumor surveillance, infectious disease, and tissue repair. The mechanisms, however, that regulate γδ T cell developmental programming remain unclear. Recently, we demonstrated that the SLAM/SAP signaling pathway regulates the development and function of multiple innate-like γδ T cell subsets.

ETS variant transcription factor 5 (ETV5), a master transcription factor during development, exerts vital function on the occurrence and progression of various cancers. In order to systematically analyze and explore ETV5 potential specific regulatory mechanisms in pan-cancer, RNA sequencing data and clinicopathological features of patients with various tumors were obtained through the Cancer Genome Atlas (TCGA) and Genotype-Tissue Expression (GTEx) databases, and an integrated data mining analysis was carried out, including the association of ETV5 expression with patient prognosis, drug sensitivity and epigenetic modification. The results revealed that abnormally highly expressed ETV5 resulted in unfavorable prognosis and differential drug sensitivity in multiple malignancies, and its expression was associated with epigenetic modification modulators including EZH2.
