Insights

Anoikis resistance in cancer involves dysregulated cell death pathways. Understanding molecular mechanisms like focal adhesion kinase (FAK) and CD44 is crucial for developing new cancer therapies.

Area of Science:

  • Cell Biology
  • Molecular Oncology

Background:

  • Anoikis, or apoptotic cell death due to loss of extracellular matrix (ECM) contact, is frequently dysregulated in diseases.
  • Understanding anoikis resistance mechanisms in cancer is critical for therapeutic development.

Purpose of the Study:

  • To review the molecular mechanisms of anoikis escalation and resistance.
  • To focus on the roles of death receptors, prosurvival pathways, and key molecular players in oral squamous cell carcinoma.

Main Methods:

  • Review of literature on anoikis, cell death pathways, and cancer biology.
  • Analysis of molecular signaling cascades involved in anoikis resistance.

Main Results:

  • Anoikis resistance can occur through constitutive activation of survival pathways (e.g., integrin-FAK-ERK).
  • Focal adhesion kinase (FAK) and receptor-interacting protein (RIP) association inhibits death-inducing signaling complex (DISC) formation, conferring resistance.
  • Up-regulation of CD44 contributes to survival signals and anoikis resistance.

Conclusions:

  • Dysregulation of anoikis plays a significant role in cancer progression.
  • Targeting specific molecular players like FAK, RIP, and CD44 may offer therapeutic strategies against oral squamous cell carcinoma.

Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

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,...
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...
Cancer Therapies02:49

Cancer Therapies

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...
Cancer Cell Migration through Invadopodia01:35

Cancer Cell Migration through Invadopodia

Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However, invadopodia can...
Cytotoxic Edema: Pathophysiology01:21

Cytotoxic Edema: Pathophysiology

Cytotoxic edema is a form of cerebral edema characterized by intracellular swelling of neurons, astrocytes, and other glial cells. It develops when the mechanisms responsible for maintaining ionic gradients across the cell membrane become impaired. Under normal physiological conditions, the sodium–potassium ATPase actively transports sodium ions out of the cell and potassium ions into the cell, preserving osmotic balance and enabling electrical signaling. This pump requires a continuous supply...
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...
