- Non-small cell lung carcinoma (NSCLC) remains a leading cause of cancer-related mortality worldwide, with existing therapies frequently hindered by drug resistance and immunosuppression. Metabolic reprogramming (glycolysis, lipid metabolism, and amino acid metabolism) has emerged as a core hallmark driving NSCLC progression, tumor microenvironment (TME) remodeling, and treatment failure, transcending the classical Warburg effect to involve intricate cross-talk between cancer cells and stromal components. - Source: PubMed

Ke KunYan LeyeChen RongZhang ChuanrongYang WeizhuZhang ZefuLin Junqing - CD34 has long been defined as a canonical marker for endothelial progenitors as well as hematopoietic stem cells, implicating its role in vascular development and hematopoiesis. However, the precise developmental hierarchy and lineage potential of CD34 cells remain controversial. In this study, we integrated inducible genetic lineage tracing techniques, proteomics and single-cell RNA-seq (scRNA-seq) analyses to elucidate the dynamic developmental trajectory of CD34 cells during various embryonic periods in both humans and mice. Remarkably, our analyses indicated that the progeny of CD34 cells marked distinct, spatiotemporally restricted progenitor waves with divergent fates, at which point cells adopted endothelial, hematopoietic and fibroblastic fates, respectively. During gastrulation (E6.5-E8.5), an initial wave of CD34 progenitors predominantly orchestrates vasculogenesis via a Kdr-dependent mechanism. Subsequently, from E9.5 to E14.5, cell cycle activation serves as a molecular switch, facilitating the endothelial-to-hematopoietic transition (EHT) of CD34 progenitors. Unexpectedly, we identify a wave of CD34 progenitors in late embryogenesis that gives rise to fibroblasts, distinct from earlier endothelial or hematopoietic lineages. Furthermore, because umbilical cord blood is a valuable source of different circulating stem/progenitor cells, we distinguish circulating endothelial progenitors from fibroblast progenitors in human cord blood by unique molecular signatures, with GFPT2 specifically marking the fibroblast progenitors. Collectively, our study provides a high-resolution spatiotemporal atlas of CD34 cells during embryogenesis, redefining the temporal shifts of CD34 cells in cell states and offering a precise framework for manipulating CD34 cells in regenerative medicine. - Source: PubMed

Wang TingGong HuiYe GuoguoChen RuihanSun ShashaHuang XueyinZhang BohuanJiang LiujunZhang YueshengChen TingtingPan YuqingXu JinghongJin MinChen KaiMao WeiXu Qingbo - Intrinsic resistance to sunitinib in advanced renal cell carcinoma (RCC) remains a major barrier to improving patient survival outcomes. However, the molecular mechanisms driving this resistance remain incompletely elucidated. In this study, we first observed elevated glutamine levels in sunitinib-resistant RCC models; notably, glutamine deprivation substantially impaired the growth and proliferation of RCC cells. We further demonstrated that abnormal upregulation of GFPT2-a key enzyme in glutamine metabolism-was associated with reduced sunitinib sensitivity and enhanced drug resistance in RCC. Mechanistically, we uncovered that GFPT2 modulates cellular O-GlcNAcylation levels, which in turn enhances the stability and nuclear translocation of YAP1-ultimately contributing to reduced sunitinib sensitivity. In addition, we also identified an additional non-metabolic role of GFPT2: it directly interacts with the Kelch domain of KEAP1, thereby reducing NRF2 binding to this domain and suppressing NRF2 ubiquitination-dependent degradation. Consequently, this regulatory cascade dysregulates the transcription of downstream antioxidant genes (e.g., HMOX1 and NQO1), ultimately driving NRF2-dependent sunitinib resistance in RCC. Critically, this KEAP1-NRF2 axis-mediated mechanism operates independently of GFPT2's metabolic role in regulating O-GlcNAcylation. Collectively, our findings demonstrate that GFPT2 modulates sunitinib sensitivity and drives drug resistance in RCC via dual mechanisms: a metabolic pathway (O-GlcNAcylation-YAP1) and a non-metabolic pathway (KEAP1-NRF2). Targeting the non-metabolic functions of GFPT2 thus holds promise for enhancing sunitinib sensitivity in RCC while potentially mitigating treatment-related side effects. - Source: PubMed

Wang SongboXing JiajunWang XiaoyiWang ZengjunShao PengfeiMiao Chenkui - Wnt signaling is a key driver of colorectal cancer (CRC) progression, yet directly inhibiting it remains a major challenge. MicroRNAs (miRNAs) are small noncoding RNAs that post-transcriptionally regulate gene expression, thereby modulating oncogenic pathways. However, the role of miR-27a-5p and its underlying mechanisms in CRC remains largely unknown. - Source: PubMed
