Insights

Melanomas evade apoptosis, programmed cell death, enabling progression and therapy resistance. Understanding altered death receptor regulation in melanoma is key to overcoming this resistance.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cell Death Research

Background:

  • Melanomas exhibit impaired apoptosis, contributing to progression, metastasis, and therapeutic resistance.
  • Understanding the mechanisms of apoptosis evasion is crucial for developing effective melanoma treatments.

Purpose of the Study:

  • To summarize current knowledge on how altered death receptor regulation contributes to melanoma's resistance to apoptosis.
  • To highlight key molecular players involved in melanoma's evasion of programmed cell death.

Main Methods:

  • Review and synthesis of existing research on melanoma apoptosis evasion.
  • Analysis of genomic, transcriptional, and post-translational alterations affecting signaling pathways.

Main Results:

  • Melanomas escape apoptosis through diverse mechanisms.
  • Alterations in G-proteins and protein kinases (Ras, B-Raf) and their transcription factors (c-Jun, ATF2, Stat3, NF-kappaB) impact TNF, Fas, and TRAIL receptor signaling.
  • These changes are critical for melanoma's resistance to apoptosis.

Conclusions:

  • Altered regulation of death receptors is a significant factor in melanoma development and resistance.
  • Targeting these altered pathways may offer new therapeutic strategies for melanoma.

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR activation may...
Apoptosis01:30

Apoptosis

Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size reduction of the tissue.
The Extrinsic Apoptotic Pathway01:17

The Extrinsic Apoptotic Pathway

The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...
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...

Cellular Injury V: Apoptosis and Autophagy

Cells respond to damage and stress through highly coordinated processes that decide whether they survive or undergo controlled self-destruction. Two major pathways involved in this regulation are apoptosis, a type of programmed cell death, and autophagy, a survival mechanism that helps cells adapt to adverse conditions.ApoptosisApoptosis removes aged or injured cells to maintain tissue balance. During this process, the cell shrinks, chromatin condenses and fragments, and membrane-bound...
