Insights

Protein kinase C (PKC) involvement in cancer is complex, with varying roles depending on the specific enzyme and cell type. This review examines current data on PKC in oncogenesis, focusing on clinical outcomes.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Oncology

Background:

  • Protein kinase C (PKC) are serine-threonine kinases involved in cellular signaling.
  • Deregulated PKC expression is observed in various cancers, but their roles can be isoform- and cell type-specific, exhibiting both pro- and anti-proliferative effects.
  • The precise involvement of PKC in tumor development remains incompletely understood.

Purpose of the Study:

  • To review current data on the role of Protein Kinase C (PKC) in oncogenesis.
  • To emphasize the clinical outcomes associated with PKC dysregulation and therapeutic strategies.
  • To provide a comprehensive overview of PKC's complex involvement in cancer development.

Main Methods:

  • Literature review of existing studies on PKC and cancer.
  • Analysis of data on PKC isoform expression in different tumor types.
  • Evaluation of clinical trial data and outcomes related to PKC-targeting agents.

Main Results:

  • PKC's role in oncogenesis is complex and highly variable, depending on the specific PKC isoform and cellular context.
  • Evidence suggests both tumor-promoting and tumor-suppressing functions for different PKC members.
  • Clinical data on agents targeting PKC in cancer treatment show variable outcomes, necessitating further research.

Conclusions:

  • Understanding the specific roles of PKC isoforms in cancer is crucial for developing effective therapies.
  • Targeting PKC in cancer treatment requires careful consideration of isoform specificity and potential side effects.
  • Further research is needed to fully elucidate PKC's complex role in oncogenesis and optimize therapeutic strategies.

Protein Kinases and Phosphatases

Proteins undergo chemical modifications that trigger changes in the charge, structure, and conformation of the proteins. Phosphorylation, acetylation, glycosylation, nitrosylation, ubiquitination, lipidation, methylation, and proteolysis are various protein modifications that regulate protein activity. Such modifications are usually enzyme-driven.

cAMP-dependent Protein Kinase Pathways

Cyclic Adenosine Monophosphate (cAMP) is an essential second messenger that activates protein kinase A (PKA) and regulates various biological processes. A single epinephrine molecule binds to GPCR and activates several heterotrimeric G proteins, each stimulating multiple adenylyl cyclase, amplifying the signal, and synthesizing large numbers of cAMP molecules. Small changes in cAMP concentration affect PKA activity. The binding of four cAMP molecules induces a conformational change in PKA,...

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a rapamycin-insensitive companion...
Calmodulin-dependent Signaling01:16

Calmodulin-dependent Signaling

Calmodulin (CaM) is a calcium-binding protein in eukaryotes that controls various calcium-regulated cellular processes. It has four calcium-binding sites that bind calcium to form the calcium-calmodulin ( Ca2+-CaM) complex. GPCR stimulation increases the calcium levels in the cells that bind to CaM and induces a conformational change.
The Ca2+-CaM complex does not have enzymatic activity by itself. Instead, the complex binds downstream target proteins, including membrane proteins or enzymes,...
Anaphase Promoting Complex00:50

Anaphase Promoting Complex

The stepwise destruction of specific proteins is necessary for the progression and completion of the cell cycle. Such proteins are ubiquitinated by ubiquitin ligases and then subsequently destroyed by the proteasome. The SCF (Skp1/Cullin/F-box) and the anaphase-promoting complex (APC) are two important ubiquitin ligases involved in cell cycle progression. While SCF is active throughout the cell cycle, APC gets activated during metaphase to anaphase transition. Cdc20 or Cdh1 binds to APC and...
