Hypoxia is a common feature in tumors, driving pathways that promote epithelial-to-mesenchymal transition, invasion, and metastasis. Clinically, high levels of hypoxia-inducible factor (HIF) expression and stabilization at the primary site in many cancer types is associated with poor patient outcome Abstract Metastasis is the leading cause of mortality in most patients with cancer. Despite its clinical importance, mechanistic underpinnings of metastatic progression remain poorly understood. Hypoxia, a condition of insufficient oxygen availability, frequently occurs in solid tumors because of their high oxygen/nutrient demand and abnormal tumor vasculature. In this

Hypoxia is a common feature of solid tumors, and develops because of the rapid growth of the tumor that outstrips the oxygen supply, and impaired blood flow due to the formation of abnormal blood vessels supplying the tumor. It has been reported that tumor hypoxia can: activate angiogenesis, thereby enhancing invasiveness and risk of metastasis; increase

Cancer and Metastasis Reviews -Hypoxia and cancer PREFACE Published: 03 April 2007 Volume 26, pages 223–224, (2007) Cite this article Abstract Metastatic disease is the leading cause of cancer-related deaths and involves critical interactions between tumor cells and the microenvironment. Hypoxia is a potent microenvironmental factor promoting metastatic progression. Clinically, hypoxia and the expression of the hypoxia-inducible transcription factors HIF-1 and HIF-2 are associated with A hypoxia-induced exosomal circRNA, circPLEKHM1, drives lung cancer metastasis by educating macrophages in the tumor microenvironment. circPLEKHM1 functions as a scaffold for PABPC1-eIF4G interaction to facilitate the translation of the oncostatin M receptor, polarizing macrophages towards to M2 type for cancer metastasis. circPLEKHM1 is a

Hypoxia is an important feature of the tumor microenvironment, and is closely associated with cell proliferation, angiogenesis, metabolism and the tumor immune response. All these factors can further promote tumor progression, increase tumor aggressiveness, enhance tumor metastatic potential and lead to poor prognosis. In this review, these effects of hypoxia on tumor biology Reflecting these major roles in cancer biology and therapy, there is compelling evidence that hypoxia can compromise clinical outcomes in human cancer (Table 2). Abstract Hypoxia is a common feature of solid tumors, and develops because of the rapid growth of the tumor that outstrips the oxygen supply, and impaired blood flow due to the formation of abnormal blood vessels supplying the tumor. It has been reported that tumor hypoxia can: activate angiogenesis, thereby enhancing invasiveness and risk of metastasis; increase survival of

Hypoxia is linked to cancer spread and resistance to conventional therapies like chemotherapy and radiotherapy, indicating a grim prognosis for various cancers, including BC, hepatocellular carcinoma (HCC), and cancers of the pancreas, stomach, and colorectum (24). Therefore, targeting hypoxia is seen as a viable strategy in cancer Hypoxia induces ZHX2 phase separation via a proline-rich intrinsically disordered region (IDR), enhancing phosphorylation of ZHX2 at S625 and S628 that incorporates CCCTC-binding factor (CTCF) in condensates to alter chromatin looping, consequently driving metastatic gene transcription and cancer metastasis.

Hypoxia occurs in 90% of solid tumors and is associated with metastasis and mortality. Breast cancer cells that experience intratumoral hypoxia are 5x more likely to develop lung metastasis in Immune evasion is a hallmark of cancer, enabling tumor cells to escape from anti-tumor immunity. Hypoxia is a well-known feature of almost all solid cancers and a characteristic of cold immunity. It accounts for impaired immunity, alterations in tumor metabolism and cancer progression toward metastasis [1], [2]. Hypoxic tumor microenvironment (TME) influences Hypoxia and HIF activity have been linked to the control of all hallmarks of cancer, and increased levels of hypoxia or HIFs in human tumours are typically associated with poor prognosis. In this review, we describe the current knowledge about the role of hypoxic signalling in tumour metastasis, which is the main cause of cancer

Diminished oxygen availability, termed hypoxia, within solid tumors is one of the most common characteristics of cancer. Hypoxia shapes the landscape of the tumor microenvironment (TME) into a pro-tumorigenic and pro-metastatic niche through arrays of pathological alterations such as abnormal vasculature, altered metabolism, immune

It also stimulates complex cancer signaling networks, including PI3K and MAPK pathways. We have discussed how hypoxia regulates progression of various cancers, including breast, ovarian, cervical, and prostate, and their metastasis, angiogenesis, and drug resistance for better understanding of the implications of hypoxia in cancer This book reviews the central role of hypoxia in cancer initiation and progression. It discusses the mechanisms of hypoxia in chemoresistance, radioresistance, angiogenesis, vasculogenesis, metastasis, metabolic, and genomic instability. It also explores the potential of hypoxia in the diagnosis and treatment of cancer. The book provides an overview of hypoxia However, it is still unclear whether hypoxic cancer cells may promote the metastasis of normoxic cells, which have greater access to the blood circulation.

Metastatic disease is the leading cause of cancer-related deaths and involves critical interactions between tumor cells and the microenvironment. Hypoxia is a potent microenvironmental factor promoting metastatic progression. Clinically, hypoxia and the expression of the hypoxia-inducible transcription factors HIF-1 and HIF-2 are associated with Hepatocellular carcinoma (HCC) is one of the most common cancers with a relatively high cancer-related mortality. The uncontrolled proliferation of HCC consumes a significant amount of oxygen, causing the development of a hypoxic tumor microenvironment (TME). Hypoxia-inducible factors (HIFs), crucial regulators in the TME, activate several cancer

Hypoxia is mediated by the complex hypoxia inducible factor (HIF) signaling pathway and plays an important role in the formation of a highly immunosuppressive microenvironment and the metastasis of pancreatic cancer. Breast cancer has been the leading cause of female cancer deaths for decades. Intratumoral hypoxia, mainly caused by structural and functional abnormalities in microvasculature, is often associated with a more aggressive phenotype, increased risk of metastasis and resistance to anti-malignancy Fat mass and obesity-associated protein (FTO), an N6-methyladenosine (m6A) demethylase, participates in tumor progression and metastasis in many malignancies, but its role in colorectal cancer

Abstract: Hypoxia is a non-physiological level of oxygen tension, a phenomenon common in a majority of malignant tumors. Tumor-hypoxia leads to advanced but dysfunctional vasculariza-tion and acquisition of epithelial-to-mesenchymal transition phenotype resulting in cell mobility and metastasis. Hypoxia alters cancer cell metabolism and contributes to therapy resistance by Accumulating evidence has shown that the hypoxic microenvironment, which is critical during cancer development, plays a key role in regulating breast cancer progression and metastasis. The effects of hypoxia-inducible factor 1 (HIF-1), a master regulator of the hypoxic response, have been extensively studied during these processes. In this review, we focus on the roles of HIF-1
