Cancer-Critical Genes I: Proto-oncogenes

Cancer-Critical Genes I: Proto-oncogenes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

Inhibition of Cdk Activity

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

Interactions Between Signaling Pathways

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

Summary

Protein kinases C (PKCs) promote tumor growth by enhancing cellular signaling pathways. This review examines classical PKCs

Area of Science:

Biochemistry
Molecular Biology
Oncology

Background:

Protein kinases C (PKCs) are serine/threonine kinases implicated in tumor formation and progression.
PKC overexpression contributes to cell transformation, acting as tumor promoters rather than classical oncogenes.
Evidence increasingly highlights the role of various PKC isoforms in cancer development over the past two decades.

Purpose of the Study:

To review the role of classical protein kinases C (PKCs) in cancer.
To analyze the therapeutic potential of inhibiting classical PKC isoforms for cancer treatment.

Main Methods:

Review of scientific literature focusing on classical PKC isoforms and their involvement in cancer.
Analysis of studies developing and testing small molecular weight inhibitors and antisense molecules targeting classical PKCs.

Published on: February 21, 2019

Main Results:

Classical PKCs play a significant role in multiple cancer signaling pathways.
Targeted inhibition of classical PKC isoforms has been explored as a therapeutic strategy.
Development of specific inhibitors (small molecules, antisense) against calcium-dependent classical PKC isoforms.

Conclusions:

Classical PKCs are important targets in cancer therapy due to their role as tumor promoters.
Inhibiting classical PKC isoforms offers a potential therapeutic avenue for cancer treatment.
Further research into PKC-targeted therapies is warranted.
