Abstract

Insights

Pancreatic cancer, a deadly disease, involves abnormal protein kinase expression. Key regulators from cell cycle and MAP-kinase pathways drive tumor progression and pancreatic ductal adenocarcinoma malignancy.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • Pancreatic cancer is a highly lethal malignancy with a dismal patient prognosis.
  • Aberrant protein kinase expression is a hallmark of pancreatic ductal adenocarcinoma (PDAC).

Purpose of the Study:

  • To investigate the role of protein kinases and their regulators in pancreatic cancer progression.
  • To identify key signaling pathways involved in pancreatic ductal adenocarcinoma malignancy.

Main Methods:

  • Microarray-based gene expression analysis was employed to identify aberrantly expressed protein kinases.
  • Analysis focused on regulatory proteins within the cell cycle control and mitogen-activated protein (MAP)-kinase pathways.

Main Results:

  • Protein kinases are frequently dysregulated in pancreatic ductal adenocarcinoma.
  • Regulatory proteins from the cell cycle and MAP-kinase pathways significantly impact cancer progression.

Conclusions:

  • Both the cell cycle control and MAP-kinase signaling pathways are critical for tumor progression in pancreatic cancer.
  • These pathways are essential for the overall malignancy of pancreatic ductal adenocarcinoma (PDAC).

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...
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...
Acute Pancreatitis II: Pathophysiology01:21

Acute Pancreatitis II: Pathophysiology

The pathophysiology of acute pancreatitis centers on injury to pancreatic acinar cells, which initiates a cascade of harmful intracellular events.This injury leads to premature activation of trypsinogen to trypsin in the pancreas. Trypsin then activates other digestive enzymes, such as chymotrypsin, elastase, and phospholipase A2, which begin breaking down pancreatic tissue. The resulting autodigestion causes local inflammation, tissue swelling, hemorrhage, and fat necrosis.Injured acinar cells...
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,...
Protein Kinases and Phosphatases02:54

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...
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...
