Insights

BH3-only proteins act as cellular damage sensors, initiating apoptosis to eliminate defective cells. Understanding their role in tumorigenesis may help overcome cancer

Area of Science:

  • Molecular Biology
  • Cell Biology
  • Cancer Research

Background:

  • BH3-only proteins are key regulators of apoptosis within the Bcl-2 family.
  • These proteins function as cellular damage sensors, triggering apoptosis in response to stress or DNA damage.
  • Apoptosis is crucial for removing genetically defective cells and preventing cancer development.

Purpose of the Study:

  • To review the current understanding of BH3-only proteins' roles in tumorigenesis.
  • To explore how BH3-only proteins contribute to cancer development and progression.
  • To highlight the potential of targeting BH3-only proteins for overcoming cancer treatment resistance, particularly in melanoma.

Main Methods:

  • Literature review of studies on BH3-only proteins and cancer.
  • Analysis of the mechanisms by which BH3-only proteins regulate apoptosis.
  • Focus on research involving melanoma and apoptotic resistance.

Main Results:

  • Dysregulation of BH3-only proteins can promote tumorigenesis.
  • Functional apoptosis pathways are essential for effective cancer chemotherapy.
  • Malignant melanoma often exhibits resistance to chemotherapy due to impaired apoptosis.

Conclusions:

  • Deciphering BH3-only protein functions offers insights into cancer development.
  • Manipulating cell death pathways involving BH3-only proteins may overcome apoptotic resistance in cancer.
  • Further research into BH3-only proteins is critical for advancing cancer therapy.

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
Tumor Progression02:07

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
The Tumor Microenvironment02:17

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

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 hydroxylase and factor...
The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...
