Insights

Novel genes, including ataxia telangiectasia mutated (ATM), are linked to pancreatic cancer risk. Understanding these genetic factors aids in patient risk stratification and early detection strategies for pancreatic ductal adenocarcinoma.

Area of Science:

  • Genetics
  • Oncology
  • Molecular Biology

Background:

  • Next-generation sequencing is revealing new genes associated with pancreatic cancer susceptibility.
  • The ataxia telangiectasia mutated (ATM) gene, a key DNA repair kinase, has emerged as a significant factor.

Purpose of the Study:

  • To investigate the role of novel susceptibility genes, specifically ATM, in pancreatic cancer.
  • To understand the implications of ATM variants and loss in pancreatic ductal adenocarcinoma (PDAC) development.

Main Methods:

  • Utilized next-generation sequencing to identify novel pancreatic cancer susceptibility genes.
  • Analyzed germline and somatic alterations in the ATM gene in PDAC patients.

Main Results:

  • Pathogenic germline ATM variants are common in PDAC patients, irrespective of family history.
  • Loss of ATM function is a frequent somatic event during PDAC development.

Conclusions:

  • Discoveries of genes like ATM significantly advance the understanding of pancreatic cancer genetics.
  • These findings will enable improved patient risk stratification, personalized screening, and targeted therapies for 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...

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...

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,...

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...

Phosphorylation01:02

Phosphorylation

The addition or removal of phosphate groups from proteins is the most common chemical modification that regulates cellular processes. These modifications can affect the structure, activity, stability, and localization of proteins within cells as well as their interactions with other proteins.
During phosphorylation, protein kinases transfer the terminal phosphate group of ATP to specific amino acid side chains of substrate proteins. Serine, threonine, and tyrosine are the most commonly...
