Insights

Migrastatics, a new drug class, target p21-activated kinases (PAKs) to inhibit breast cancer metastasis. This review explores how PAKs drive actin dynamics crucial for cancer cell invasion and discusses PAK migrastatics in clinical settings.

Area of Science:

  • Oncology
  • Cell Biology
  • Biochemistry

Background:

  • Metastatic breast cancer has a poor 25% survival rate.
  • Current treatments do not target cancer metastasis.
  • Migrastatics are an emerging drug class designed to inhibit cancer cell invasion and metastasis by targeting migration pathway effector proteins.

Purpose of the Study:

  • To review the role of p21-activated kinases (PAKs) in regulating actin dynamics in breast cancer cell migration and invasion.
  • To highlight PAKs as potential targets for novel migrastatic therapeutics.
  • To discuss the clinical potential of PAK migrastatics in breast cancer treatment.

Main Methods:

  • Review of existing literature on PAKs and breast cancer metastasis.
  • Analysis of PAK regulation of actin cytoskeletal dynamics, including cytoskeletal reorganisation, cell:matrix adhesion, actomyosin contractility, and degradative invasion.
  • Discussion of the clinical pipeline for migrastatic drug development.

Main Results:

  • PAKs are essential drivers of breast cancer cell migration and invasion.
  • PAKs regulate key aspects of actin dynamics that facilitate metastasis.
  • PAKs represent attractive targets for the development of migrastatic drugs.

Conclusions:

  • Targeting PAKs offers a promising strategy for developing novel migrastatic therapies for metastatic breast cancer.
  • Understanding PAK-mediated actin dynamics is crucial for designing effective anti-metastatic drugs.
  • The integration of PAK migrastatics into the breast cancer clinical pipeline holds significant therapeutic potential.

Actin Filament Depolymerization01:19

Actin Filament Depolymerization

Actin filaments (F-actin) are composed of actin subunits. The dissociation of actin monomers can occur from either end of F-actin. The rate of dissociation is faster from the minus-end or the pointed end, where the actin subunits exist with a bound ADP, together known as ADP-actin. The depolymerization of F-actin is aided by proteins, including the actin-depolymerizing factor (ADF) and cofilin family of proteins, gelsolin, and glia maturation factor (GMF).
In F-actin, the ADF/cofilin proteins...

Actin Polymerization and Cell Motility01:13

Actin Polymerization and Cell Motility

Actin is a family of globular proteins that are highly abundant in eukaryotic cells. It makes up approximately 1-5% of total cell protein concentration. Actin monomers polymerize to form a complex network of polarized filaments, the actin cytoskeleton, that plays a crucial role in many cellular processes, including cell motility, division, endocytosis, and metastasis of cancer cells.
Actin cytoskeleton dynamics can produce pushing, pulling, and resistance forces that help the cell to migrate....

Generation of Straight or Branched Actin Filaments01:14

Generation of Straight or Branched Actin Filaments

The straight or branched structure formation of actin filaments is controlled by nucleating proteins such as the formins and Arp2/3 complex. Formin-mediated assembly results in straight filaments, whereas Arp2/3 protein complex-mediated assembly results in branched actin filaments.
Arp2/3 Complex
Arp2/3 complex is a seven-subunit complex consisting of two proteins similar to actin- Arp2 and Arp3, and five other subunits that help keep Arp2 and Arp3 inactive. When required, the complex is...

Destabilization of Microtubules01:45

Destabilization of Microtubules

The destabilization of microtubules can occur during different stages of the microtubule lifecycle, such as nucleation or elongation. It can take place at either end of the microtubule or in the microtubule lattices as a whole. The lifespan of individual microtubules within a cell varies according to the cell type and stage of the cell cycle. During interphase, the lifespan of the microtubule is about 30 minutes, while during cell division, it is about 15 minutes. In axonal microtubules of...

Mechanism of Lamellipodia Formation01:31

Mechanism of Lamellipodia Formation

Cells migrating in response to external stimuli form lamellipodia, which are thin membrane protrusions supported by a mesh of linked, branched, or unbranched actin filaments. These actin filaments interact with myosin motor proteins, creating the dynamic actomyosin complex within the cytoskeleton. Contractility, or the ability to generate contractile stress, is inherent to the actomyosin complex. It helps cells detect the stiffness of the surrounding ECM and exert contractile force for...

Introduction to Actin01:26

Introduction to Actin

Actin is a highly conserved cytoskeletal protein found abundantly in eukaryotic cells. It constitutes 10% weight of the total cellular protein in muscle cells, while in non-muscle cells, it is lower and makes up around 1–5 percent of the total cell protein. Actin found in the unicellular amoebae and complex multicellular animals is around 80% similar, demonstrating their conservation over a billion years of evolution.  Actin coding genes are conserved within species and across...
