ETS-1, a key member of the Erythroblast Transformation-Specific (ETS) transcription factor family, plays an important role in cell biology and medical research due to its wide expression profile strong transcriptional regulation ability. It regulates fundamental biological processes, including proliferation, differentiation, apoptosis, is involved tumorigenesis metastasis, promoting malignant behaviors such as angiogenesis, matrix degradation, migration. Given association between ETS-1 overexpression aggressive characteristics multiple malignancies, it represents promising therapeutic target cancer treatment. This study aims systematically analyze within tumor immune microenvironment, elucidating mechanisms initiation, progression, metastasis. also investigates differential across tissues adjacent normal tissues, exploring potential molecular marker for diagnosis prognosis.

SUMMARY Axonal degeneration underlies neuromuscular disorders and neuropathies. Dysregulation of neurotrophic factors, such as brain-derived factor (BDNF), in the peripheral nervous system has long been established to exacerbate axonopathy. However, molecular programs controlled by BDNF that facilitate axonal regeneration transport are not well-understood. Here, we unravel transcriptomic phosphorylation landscape shaped human iPSC-derived motor neurons. Using SLAM-Seq, reveal stimulation increases global transcription rate neurons governs gene regulatory networks converge with those engaged during repair/outgrowth. Phosphoproteomic analyses demonstrate remodels cytoskeletal-binding proteins, especially structural microtubule-associated proteins. Importantly, localized axonal-specific activation ERK1/2 is necessary for enhance neurotrophin-containing signaling endosomes potentiate after axotomy. Collectively, this work unveils a novel paradigm positions core regulator transcriptional driving HIGHLIGHTS SLAM-seq reveals increased modulates outgrowth/regeneration proteins BDNF-ERK1/2 controls
