Correlation of GD2 Biosynthesis Enzymes With Cancer Stem Cell Markers in Human Breast Cancer.

Background/aim: The disialoganglioside GD2 has been shown to promote cell proliferation, migration, tumor and metastasis through specific signaling pathways in tumor cells originating from the neuroectoderm, including melanomas, neuroblastomas, glioblastomas, and breast carcinomas. GD2 has therefore emerged as a potential diagnostic biomarker in early malignancy as evidenced by the high specificity of its expression in tumor cells. Furthermore, recent findings show that GD2 might also act as a novel cancer stem cell (CSC) marker.

Cellular Impacts of Striatins and the STRIPAK Complex and Their Roles in the Development and Metastasis in Clinical Cancers (Review).

Striatins (STRNs) are generally considered to be cytoplasmic proteins, with lower expression observed in the nucleus and at cell-cell contact regions. Together with protein phosphatase 2A (PP2A), STRNs form the core region of striatin-interacting phosphatase and kinase (STRIPAK) complexes through the coiled-coil region of STRN proteins, which is crucial for substrate recruitment. Over the past two decades, there has been an increasing amount of research into the biological and cellular functions of STRIPAK members.

Metastatic Lymph Node 64 (MLN64) Expression in Gastric Cancer: The Clinical and Molecular Implications in Drug Resistance.

Background/aim: Metastatic lymph node 64 (MLN64) is often co-amplified with ERBB2 (HER2) and plays a role in the progression of breast and prostate cancer. The present study explored the expression of MLN64 in clinical gastric cancer in association with the ERBB family and its impact on drug resistance in patients.

Materials And Methods: Two independent gastric cancer cohorts (n=324; n=87) were used to explore the expression profile of MLN64 in conjunction with ERBB family members in clinical gastric cancer and its association with neoadjuvant chemotherapy responses.

Striatins and STRIPAK complex partners in clinical outcomes of patients with breast cancer and responses to drug treatment.

Objective: Striatins (STRNs) family, which contains three multi-domain scaffolding proteins, are cornerstones of the striatins interacting phosphatase and kinase (STRIPAK) complex. Although the role of the STRIPAK complex in cancer has become recognized in recent years, its clinical significance in breast cancer has not been fully established.

Methods: Using a freshly frozen breast cancer tissue cohort containing both cancerous and adjacent normal mammary tissues, we quantitatively evaluated the transcript-level expression of all members within the STRIPAK complex along with some key interacting and regulatory proteins of STRNs.

The Clinical and Theranostic Values of Activated Leukocyte Cell Adhesion Molecule (ALCAM)/CD166 in Human Solid Cancers.

Activated leukocyte cell adhesion molecule (ALCAM), also known as CD166, is a cell adhesion protein that is found in multiple cell types. ALCAM has multiple and diverse roles in various physiological and pathological conditions, including inflammation and cancer. There has been compelling evidence of ALCAM's prognostic value in solid cancers, indicating that it is a potential therapeutic target.

NUPR1 and its potential role in cancer and pathological conditions (Review).

Nuclear protein‑1 (NUPR1) is also known as Com‑1 or p8. It is a protein primarily found in the nucleus of various cells, including cancer cells, and it has been found to play an important role in cell stress and stress‑related apoptosis. Over the past two decades, NUPR1 has been firmly indicated to play a role in the development and progression of numerous types of cancer, as well as in a number of other pathological conditions, including pancreatitis, diabetes, neurological and inflammatory conditions.
