Integrins, crucial cell surface receptors, mediate cell-matrix and cell-cell interactions. This review details their structure, signaling, and roles in cell functions, cancer, and apoptosis.

Area of Science:

  • Cell Biology
  • Molecular Biology
  • Biochemistry

Background:

  • Integrins are transmembrane glycoproteins on cell surfaces.
  • They act as receptors for extracellular matrix and cell-cell adhesion.
  • Integrins also transduce signals affecting cell physiology.

Purpose of the Study:

  • To present current understanding of integrin molecular structure.
  • To discuss integrin involvement in cytoskeleton organization and gene regulation.
  • To analyze integrin roles in cancer and apoptosis.

Main Methods:

  • Literature review of contemporary research on integrins.
  • Analysis of biochemical mechanisms of integrin signaling.
  • Examination of data on integrin participation in oncogenesis.

Main Results:

  • Integrins are key in cell adhesion and signal transduction.
  • Their structure is linked to cytoskeleton organization and gene activity.
  • Integrins play significant roles in cell transformation, metastasis, and apoptosis.

Conclusions:

  • Integrins are vital for cell-matrix and cell-cell interactions.
  • Understanding integrin signaling is crucial for cell physiology.
  • Integrins are implicated in cancer progression and programmed cell death.
