Lipid metabolic reprogramming in clear cell renal cell carcinoma: focus on high-density lipoprotein-related pathways

Lize Wu, Huaying Xue, Yifei Wu, Ningning Shen, Zhiqing Yang, Lifang Gao, Wenxia Ma, Chen Wang

Clear cell renal cell carcinoma (ccRCC) is one of the most prevalent solid tumors characterized by lipid metabolic reprogramming, with extensive lipid droplet accumulation in tumor cells as a hallmark feature. Traditionally, this phenotypic trait is attributed to enhanced fatty acid synthesis, increased triglyceride (TG) storage, and impaired β-oxidation. However, emerging transcriptomic and lipidomic evidence suggests that cholesterol metabolism is also profoundly reprogrammed in ccRCC, particularly via increased …

ZEB1 directly activates IL-6 to promote triple-negative breast cancer stemness in an epigenetically constrained context

Weiyue Zhang, Yifan Zhou, Wei Ma, Huimin Jiang

ZEB1 is a key driver of breast cancer pathogenesis and therapy resistance, largely through its ability to promote cancer stem cells (CSCs). Although tumor-secreted cytokines such as IL-6 are known to support tumor progression, how their expression is regulated by upstream transcriptional factors such as ZEB1 remains incompletely understood. Here, we identify IL-6 as a direct transcriptional target of ZEB1 and reveal an epigenetic dimension associated with this regulation. Mechanistically, ZEB1 binds to specific E2- …

Encapsulated multicellular breast cancer spheroids exhibit behavioural plasticity under non-negotiable mechanical stress

Sukanya Gayan, Saili S. Shinde, Asadullah, Anisha Karmakar, Shamik Sen, Tuli Dey

Abstract Cancerous growth, along with other known biological and biochemical signals, also depends on the biomechanical pressure wielded by the adjacent extracellular matrix (ECM). The dynamic relationship between the growing tumor and the ECM influences tumor growth, aggressiveness, and dormancy. Additionally, with time, the stroma also becomes subject to tumor-mediated remodeling through deformation and deposition cycles. In recent years, many studies have identified the dialog between the ECM and the tumor as on …

Targeting the PD-L1-induced PDK4/GLS metabolic axis overcomes anti-PD-1 resistance in non-small cell lung cancer

Wenxin Lian, Hui Yang, Yuqi Zhang, Chenchen Liu, Chunyao Fang, Mengyue Xu, Yixing Yang, Yan Wang, Runqiu Jiang, Jing Xu, Wen Gao

Background Metabolic reprogramming within the tumor microenvironment is a pivotal barrier to effective immune checkpoint blockade (ICB). While programmed death ligand 1 (PD-L1) is well characterized as a ligand inhibiting T-cell function, its intrinsic ‘reverse signaling’ role in regulating tumor metabolism and shaping the immune landscape remains poorly understood. Here, we investigated the metabolic determinants of resistance to anti-programmed cell death protein 1 (anti-PD-1) therapy and the underlying molecular …
