Abstract

Insights

Platelet-derived growth factor receptor-beta (PDGFRbeta) is significantly upregulated in esophageal carcinoma tissues compared to normal tissues. C-kit expression was low and not significantly different across tissue types in this study.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Context:

  • STI-571 is known to inhibit tyrosine kinases including C-kit and platelet-derived growth factor receptor-beta (PDGFRbeta).
  • These kinases play roles in cell differentiation, proliferation, and apoptosis.
  • Esophageal carcinoma is a significant global health concern.

Purpose:

  • To investigate the expression levels of C-kit and PDGFRbeta in esophageal carcinoma.
  • To determine the correlation between C-kit and PDGFRbeta expression and esophageal carcinoma characteristics.

Summary:

  • Immunohistochemistry was used to assess C-kit and PDGFRbeta expression in 50 esophageal carcinoma specimens (tumor, para-tumor, and normal tissues).
  • Strong PDGFRbeta expression was significantly higher in tumor tissues (68%) compared to para-tumor (28%) and normal tissues (28%) (P=0.001).
  • Strong C-kit expression was low across all tissue types (tumor 4%, para-tumor 4%, normal 12%) with no significant difference (P=0.220).

Impact:

  • Results indicate that PDGFRbeta is a potential biomarker for esophageal carcinoma.
  • C-kit expression does not appear to be significantly altered in esophageal carcinoma.
  • Further research may explore targeted therapies involving PDGFRbeta in esophageal cancer treatment.

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.
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...
Receptor Tyrosine Kinases01:26

Receptor Tyrosine Kinases

Receptor tyrosine kinases or RTKs are membrane-bound receptors that phosphorylate specific tyrosine on protein substrates. RTKs regulate cellular growth, differentiation, survival, and migration. They contain an extracellular ligand binding domain, a transmembrane domain, and a cytosolic tail with intrinsic kinase activity. Several extracellular signaling molecules activate RTKs in one or more ways and relay the signal downstream. Ligands such as platelet-derived growth factor (PDGF) or...
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...
