Summary
Protein ubiquitylation and hypoxia are key in cancer. This review explores how deubiquitinases (DUBs) and hypoxia-inducible factors (HIFs) interact, highlighting DUBs as potential cancer drug targets.
Area of Science:
- Biochemistry
- Molecular Biology
- Oncology
Background:
- Protein ubiquitylation and cellular hypoxia are frequently altered in cancer.
- Deubiquitinases (DUBs) counteract ubiquitylation and are emerging as significant therapeutic targets.
- Ubiquitylation regulates the degradation of key proteins, including hypoxia-inducible factors (HIFs).
Purpose of the Study:
- To review the intricate relationship between E3 ubiquitin ligases, DUBs, and hypoxia signaling pathways in cancer.
- To elucidate the less-understood regulation of DUBs by hypoxia and their subsequent impact on HIFs.
- To discuss the potential of DUB-specific drugs in cancer therapy.
Main Methods:
- Literature review of existing research on ubiquitylation, DUBs, hypoxia, and cancer.
- Analysis of the reciprocal regulatory mechanisms between hypoxia and DUBs.
- Examination of the role of DUBs in controlling HIF abundance and function.
Main Results:
- Hypoxia significantly influences HIF levels, partly through the action of E3 ligases and DUBs.
- Several E3 ligases and DUBs are themselves regulated by hypoxic conditions.
- The interplay between DUBs and hypoxia presents a complex regulatory network impacting cancer progression.
Conclusions:
- DUBs play a critical role in regulating HIFs, a key pathway in cancer.
- Understanding hypoxia-regulated DUBs is crucial for developing novel cancer treatments.
- Targeting DUBs offers a promising therapeutic strategy for cancers associated with altered hypoxia signaling.

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

Hypoxia is a medical condition characterized by an inadequate oxygen supply to body tissues. It typically manifests as a bluish discoloration of the skin and mucosae, especially in fair-skinned individuals, when hemoglobin (Hb) saturation drops below 75%.
Types of Hypoxia
There are four primary types of hypoxia, each resulting from a different cause:
1. Anemic hypoxia: This type occurs due to insufficient oxygen delivery caused by a lack of red blood cells (RBCs) or RBCs with abnormal or...

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Hemoglobin (Hb) is a crucial molecule in the human body, consisting of four polypeptide chains, each bound to an iron-containing heme group. This unique structure enables hemoglobin to bind to oxygen, with each molecule capable of combining with four molecules of oxygen, leading to rapid and reversible oxygen loading. When fully loaded with oxygen, it is called oxyhemoglobin, while hemoglobin that has released oxygen is called reduced hemoglobin or deoxyhemoglobin. As hemoglobin binds oxygen,...

53.3K
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
