Insights

Pancreatic cancer signaling involves multiple enzyme pathways, including Raf-MEK-ERK and phosphatidylinositide-3-kinase. Novel protein kinase D (PKD) family kinases are newly detected and require functional characterization in pancreatic tumors.

Area of Science:

  • Oncology
  • Molecular Biology
  • Signal Transduction

Background:

  • Extracellular signaling pathways are critical in pancreatic cancer.
  • The Raf-MEK-ERK cascade regulates apoptosis, proliferation, and metastasis.
  • Phosphatidylinositide-3-kinase signaling, via PKB/AKT and FRAP/p70s6k, promotes growth and inhibits apoptosis.

Purpose of the Study:

  • To highlight the expanding network of signaling enzymes in pancreatic cancer.
  • To introduce the role of protein kinase C (PKC) family kinases.
  • To report the recent detection of the novel protein kinase D (PKD) family in pancreatic cancer and emphasize the need for functional characterization.

Main Methods:

  • Literature review of signaling pathways in pancreatic cancer.
  • Analysis of enzyme families involved in pancreatic cancer.
  • Identification of novel kinase families in tumor tissues.

Main Results:

  • The Raf-MEK-ERK pathway is crucial for pancreatic cancer progression.
  • Phosphatidylinositide-3-kinase signaling pathways are implicated in cell growth and survival.
  • Protein kinase C (PKC) and protein kinase D (PKD) families are emerging as key modulators.

Conclusions:

  • Multiple enzyme networks significantly influence pancreatic cancer.
  • PKC family kinases modulate transformation and cell cycle.
  • PKD family kinases represent a novel target for functional studies in pancreatic cancer.

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.
Protein kinases
Many proteins in the cell are regulated by phosphorylation, the addition of a phosphate group. A family of enzymes called kinases...
mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...
Interactions Between Signaling Pathways01:19

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...
PI3K/mTOR/AKT Signaling Pathway01:22

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...
cAMP-dependent Protein Kinase Pathways01:25

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,...
