Insights

Necroptosis, a regulated cell death pathway, shows promise for treating colorectal cancer (CRC). Targeting key proteins like RIPK1, RIPK3, and MLKL could improve outcomes and overcome resistance in advanced CRC.

Area of Science:

  • Oncology
  • Cell Death Biology

Background:

  • Colorectal cancer (CRC) presents significant mortality due to limited advanced-stage treatment efficacy.
  • Necroptosis, a regulated necrotic cell death pathway involving RIPK1, RIPK3, and MLKL, offers a potential alternative for cancer cell death induction.

Purpose of the Study:

  • To systematically review the literature on necroptosis's role in colorectal cancer.
  • To analyze molecular mechanisms, experimental models, and therapeutic implications of targeting necroptosis in CRC.
  • To evaluate the potential of targeting RIPK1, RIPK3, and MLKL as a viable therapeutic strategy for CRC.

Main Methods:

  • Systematic literature review of studies on necroptosis in colorectal cancer.
  • Critical evaluation of experimental models and molecular mechanisms.
  • Analysis of therapeutic implications and clinical outcomes.

Main Results:

  • Necroptosis modulation may enhance antitumor immunity and overcome therapeutic resistance in CRC.
  • Targeting RIPK1, RIPK3, and MLKL is under investigation for its efficacy in preclinical and clinical settings.
  • Evidence suggests necroptosis plays a complex role in CRC progression and treatment response.

Conclusions:

  • Targeting necroptosis represents a potential therapeutic avenue for colorectal cancer.
  • Further research is needed to determine if targeting RIPK1, RIPK3, and MLKL is a promising strategy or a dead end for CRC therapy.
  • Modulating necroptosis could offer new hope for improving survival rates in advanced CRC patients.

Necrosis

Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...

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...
