- Although papillary thyroid carcinoma (PTC) is widely considered an immunologically cold tumor, detectable T-cell infiltration can influence disease progression in selected patients. Previous bulk analyses have linked cAMP-responsive element modulator (CREM) expression to a favorable progression-free interval and an inverse correlation with regulatory T-cell infiltration but have not resolved the cellular origin or functional state. In this study, we integrate single-cell RNA-sequencing data from a 23-sample PTC atlas with bulk Cancer Genome Atlas Thyroid Carcinoma (TCGA-THCA) validation. We show that CREM marks a T-cell receptor (TCR)-driven immediate early gene activation state in tumor-infiltrating T cells rather than a cAMP program; this state is consistently and modestly enriched within the FOXP3 regulatory T-cell compartment, challenging the interpretation that bulk inverse Treg-CREM correlations reflect Treg-intrinsic repression. CREM-high T cells upregulate ANXA1, and permutation-controlled analysis identifies a candidate paracrine axis from CD4/CD8 T cells to the epithelial epidermal growth factor receptor (EGFR). At the bulk level, CREM expression correlates with reduced proliferation programs and is associated with a prolonged progression-free interval (multivariate HR 0.56, 95% CI 0.31-1.00, = 0.050), with the effect direction preserved after immune and sex adjustment. Genome-wide differential expression and gene-set enrichment in an independent cohort (GSE193581) confirm that CREM-detected T cells are enriched for a TCR-driven immediate early transcriptional program, supporting the reinterpretation of CREM as a marker of TCR-driven IEG activation. - Source: PubMed

Ling HaoQiu PeiyuHu YanzhuSun Yan - Head and neck cancer (HNC) is characterized by substantial immune heterogeneity and limited availability of clinically actionable molecular targets. Here, we developed an integrative single-cell eQTL-driven multi-omics framework to identify immune cell-specific causal genes and prioritize drug-repurposing candidates for HNC. - Source: PubMed

Li ZhouMingrui JiangYueyang ZhouHang QiQing LiuXiaoyu YanHuimei YuMeihui Xia - Vemurafenib (VEM) is a BRAF inhibitor that improves the prognosis of melanoma, but acquired resistance represents a key limitation to its clinical efficacy. This study investigated the potential of A11, an Annexin A1 (ANXA1)-derived peptide, to enhance VEM efficacy in both VEM-sensitive and VEM-resistant melanoma cells. We evaluated the effects of A11 in melanoma through in vitro assays (including MTT, clonogenic survival, apoptosis, and cell cycle analysis) and in vivo xenograft models in nude mice. Furthermore, we mechanistically interrogated A11-mediated suppression of EphA2 expression and the downstream pS897-EphA2/AKT/ERK signalling pathway in resistant and parental cell lines via Western blotting and immunohistochemistry (IHC). Critically, our study demonstrates that A11 inhibits melanoma cell proliferation and reverses VEM resistance through EphA2 downregulation, consequently ablating this oncogenic pathway. This research highlights the promising application value of A11 in improving the efficacy of VEM treatment in melanoma, particularly in VEM-resistant melanoma. - Source: PubMed
Feng JuanHuang Xiao-PuZhang MingHuang WeiLu Shan-ShanXiao Zhi-QiangXie Zhi-HaiYi Hong - Annexin A1 (ANXA1) is a multifunctional regulatory protein involved in neuroinflammation and cellular homeostasis, but its role in amyotrophic lateral sclerosis (ALS) remains unclear. In this study, we investigated the relationship between ANXA1 and Hippo pathway signaling in ALS. Bioinformatic analysis of transcriptomic data from iPSC-derived motor neurons showed that ANXA1 expression was reduced in ALS and associated with apoptosis and Hippo pathway-related changes. Decreased ANXA1 expression was confirmed in hSOD1^G93A transgenic mice and NSC34 motor neuron-like cells. Phosphorylation levels of MST1/2, LATS1/2, and YAP1 were elevated, indicates activation of the Hippo pathway. Functional experiments showed that ANXA1 overexpression reduced Hippo pathway activation, enhanced cell viability, and decreased apoptosis, as increased Bcl-2 expression and reduced Bax and cleaved caspase-9 levels. In contrast, ANXA1 knockdown further activated Hippo pathway and aggravated apoptotic changes. These findings identify ANXA1 as an upstream regulator associated with Hippo pathway activation in ALS and suggest that the ANXA1/Hippo axis may represent a potential therapeutic target. - Source: PubMed
