    Abstract

    Insights

    Akt and Cks1 protein expression is linked to lymph node metastasis in gastric adenocarcinoma. These findings suggest Akt and Cks1 may indicate a poorer prognosis for patients with this cancer.

    Area of Science:

    • Oncology
    • Molecular Biology
    • Cancer Research

    Background:

    • The PI3K/Akt signaling pathway is implicated in cancer development and progression.
    • Akt protein influences cell proliferation regulators like p27 and Cks1.
    • Gastric adenocarcinoma is a significant global health concern.

    Purpose of the Study:

    • To examine the immunohistochemical expression of Akt, p27, and Cks1 proteins in gastric adenocarcinoma.
    • To correlate protein expression with clinicopathological parameters including lymph node metastasis, tumor invasion, TNM stage, and Lauren classification.

    Main Methods:

    • Immunohistochemical staining was performed on 43 gastric adenocarcinoma specimens.
    • Monoclonal antibodies against Akt, p27, and Cks1 were utilized.

    Main Results:

    • Increased Akt expression was observed in adenocarcinomas with lymph node involvement (53.5%) compared to those without (9.3%) (p=0.007).
    • Elevated Cks1 expression was found in adenocarcinomas with lymph node involvement (39.5%) versus those without (7%) (p<0.043).

    Conclusions:

    • Akt and Cks1 protein expression are associated with lymph node metastasis in gastric adenocarcinoma.
    • These proteins may serve as indicators of a poor prognosis in gastric adenocarcinoma.

    Metastasis02:30

    Metastasis

    Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
    Epithelial-to-Mesenchymal Transition
    The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

    Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

    Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy.  SP binds and activates these...

    Cadherins in Tissue Organization

    The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.
