Project description:Factor-inhibiting HIF (FIH) is an asparagine hydroxylase that acts on hypoxia-inducible factors (HIFs) to control cellular adaptation to hypoxia. FIH is expressed in several tumor types, but its impact in tumor progression remains largely unexplored. We observed that FIH was expressed on human lung cancer tissue. Deletion of FIH in mouse and human lung cancer cells resulted in an increased glycolytic metabolism, consistent with increased HIF activity. FIH-deficient lung cancer cells exhibited decreased proliferation. Analysis of RNA-Seq data confirmed changes in the cell cycle and survival and revealed molecular pathways that were dysregulated in the absence of FIH, including the upregulation of angiomotin (Amot), a key component of the Hippo tumor suppressor pathway. We show that FIH-deficient tumors were characterized by higher immune infiltration of NK and T cells compared with FIH competent tumor cells. In vivo studies demonstrate that FIH deletion resulted in reduced tumor growth and metastatic capacity. Moreover, high FIH expression correlated with poor overall survival in non-small cell lung cancer (NSCLC). Our data unravel FIH as a therapeutic target for the treatment of lung cancer.

Project description:T cells must adapt to variations in tissue microenvironments; these adaptations include the degree of oxygen availability. The hypoxia-inducible factor (HIF) transcription factors control much of this adaptation, and thus regulate many aspects of T cell activation and function. The HIFs are in turn regulated by oxygen-dependent hydroxylases: both the prolyl hydroxylases (PHDs) which interact with the VHL tumor suppressor and control HIF turnover, and the asparaginyl hydroxylase known as the Factor inhibiting HIF (FIH), which modulates HIF transcriptional activity. To determine the role of this latter factor in T cell function, we generated T cell-specific FIH knockout mice. We found that FIH regulates T cell fate and function in a HIF-dependent manner and show that the effects of FIH activity occur predominantly at physiological oxygen concentrations. T cell-specific loss of FIH boosts T cell cytotoxicity, augments T cell expansion in vivo, and improves anti-tumor activity in mice. Specifically inhibiting FIH in T cells may therefore represent a promising strategy for cancer immunotherapy.

Project description:Chronic psychological stress is closely linked to malignant disorders, with novel modulators potentially mitigating tumor progression by regulating interactions between neoplastic cells and immune cells. This study identified lncRNA HIF1A-AS3 as a key driver of stress-induced lung cancer progression. Chronic stress models in mice with implanted lung cancer cells revealed significant upregulation of HIF1A-AS3 in stressed groups and human lung cancer tissues. Functional studies showed HIF1A-AS3 promotes cancer cell proliferation and invasion by activating HIF-1ɑ translation through interaction with YBX1, forming a positive feedback loop where HIF-1ɑ enhances HIF1A-AS3 transcription. Additionally, HIF1A-AS3 drove macrophage M2 polarization and reduced phagocytosis under hypoxia. Targeting the HIF1A-AS3/HIF-1ɑ loop effectively counteracted stress-induced lung cancer progression in vivo, highlighting its potential as a diagnostic and therapeutic target for stress-exacerbated lung cancer.

Project description:O-GlcNAc transferase (OGT) has been reported to participate in the development of various cancers, but its role in clear cell renal cell carcinoma (ccRCC) remains unclear. In this study, we found that OGT was upregulated in ccRCC compared with paired nontumor renal tissues and was associated with worse survival. Moreover, OGT promoted the proliferation, clone formation, and invasive abilities of VHL-mutated ccRCC cells. Mechanistically, OGT promoted the expression of hypoxia-inducible factor-2α (HIF-2α) (the main driver of the clear cell phenotype) by repressing ubiquitin‒proteasome system-mediated degradation. Interestingly, the OGT/HIF-2α axis confers ccRCC sensitivity to ferroptosis, rendering it vulnerable. In conclusion, OGT promotes the progression of VHL-mutated ccRCC by inhibiting the degradation of HIF-2α. On the other hand, the OGT/HIF-2α axis renders ccRCC vulnerable to ferroptosis, suggesting that ferroptosis inducers are a promising therapy for patients with upregulated OGT and mutated VHL ccRCC.

Project description:The aspariginyl-hydroxylase activity of Factor Inhibiting HIF (FIH) is a key regulator of the transcriptional activity of the hypoxia inducible factor. FIH also catalyses the hydroxylation of asparaginyl- and other-residues in ankyrin repeat domain (ARD) containing proteins, including Apoptosis stimulating of p53 (ASPP) protein family members. ASPP2 is reported to undergo a single FIH catalysed hydroxylation at Asn-986. We report biochemical and crystallographic evidence showing FIH can catalyse the unprecedented post-translational hydroxylation of both asparaginyl-residues in “VNVN” and related motifs of ankyrin repeat domains in apoptosis-stimulating of p53 (ASPP) proteins (i.e. ASPP1, ASPP2 and iASPP) and the related ASB11 and p18-INK4C proteins. The results extend the substrate scope of FIH catalysis and may have implications for its role in the hypoxic response and, ASPP protein function.

Project description:Non-small cell lung cancer (NSCLC) is the leading cause of cancer deaths worldwide. The oxygen-sensitive Hypoxia Inducible Factor (HIF) transcriptional regulators HIF-1α and HIF-2α are overexpressed in many human NSCLCs, and constitutive HIF-2α activity can promote murine lung tumor progression, suggesting that HIF proteins may be effective NSCLC therapeutic targets. To investigate the consequences of inhibiting HIF activity in lung cancers, we deleted Hif-1α or Hif-2α in an established KrasG12D-driven murine NSCLC model. Deletion of Hif-1α had no obvious effect on tumor growth, whereas Hif-2α deletion resulted in an unexpected increase in tumor burden that correlated with reduced expression of the candidate tumor suppressor gene Scgb3a1 (HIN-1). Here, we identify Scgb3a1 as a direct HIF-2α target gene, and demonstrate that HIF-2α regulates Scgb3a1 expression and tumor formation in human KrasG12D-driven NSCLC cells. AKT pathway activity, reported to be repressed by Scgb3a1, was enhanced in HIF-2α deficient human NSCLC cells and xenografts. Finally, a direct correlation between HIF-2α and SCGB3a1 expression was observed in approximately 70% of human NSCLC samples analyzed. These data suggest that whereas HIF-2α overexpression can contribute to NSCLC progression, therapeutic inhibition of HIF-2α below a critical threshold may paradoxically promote tumor growth by reducing expression of tumor suppressor genes, including Scgb3a1. RNA was isolated from tumors of experimental (Hif2alpha deficient) mice and control mice (seven for each group).
