Interleukin-18 Facilitates Stomach Cancer Metastasis and Immune Escape

Researchers at Seoul National University in Korea have discovered that interleukin-18 (IL-18) plays a critical role in the metastasis and immune escape of stomach cancer. The investigators found that IL-18 expression is elevated in stomach cancer cell lines and tumor tissues, and that it suppresses CD70, a protein involved in

Pokeweed Antiviral Protein Shows Promise as Novel Therapeutic Agent Against HTLV-I

Researchers from York University have discovered that pokeweed antiviral protein (PAP) can effectively suppress the production of the Human T-cell leukemia virus I (HTLV-I), a deltaretrovirus that causes adult T-cell leukemia and the neurological disorder HTLV-I-associated myelopathy/tropical spastic paraparesis. The study, published in the Journal of Biological Chemistry, found

Human Papillomavirus Plays a Significant Role in Head and Neck Cancer

Human papillomavirus (HPV) has been identified as a major risk factor for head and neck squamous cell carcinoma (HNSCC), accounting for 20 to 25% of cases worldwide. Specifically, HPV has been found to be etiologically associated with cancers in the oropharynx. The virus causes cancer by expressing two oncoproteins, E6

Taxol's Therapeutic Efficacy Compromised by Cellular Resistance

Taxol, a widely used cancer drug, has been found to trigger apoptosis in various cancer cells, including SKOV3 human ovarian cancer cells. However, researchers have discovered that Taxol treatment can also upregulate cytoprotective proteins, such as alpha-2,3-sialyltransferase (ST3Gal III), which can compromise its therapeutic efficacy. The study, published in

SLA2 Mutations Cause SWE1-Mediated Cell Cycle Phenotypes in Candida albicans and Saccharomyces cerevisiae

Scientists in the United States have made a significant discovery regarding the mechanisms governing morphogenesis and growth rates in Saccharomyces cerevisiae and Candida albicans. Specifically, they found that mutations in the SLA2 gene lead to cell cycle delays and defects in actin cables, which are crucial for the proper functioning

Mutant p53 Gains Antiapoptotic Function through STAT3 in Anaplastic Thyroid Cancer Cells

Recent research from South Korea has identified a missense mutation (G199V) in the KAT-18 cell line established from primary cultures of anaplastic thyroid cancer. The study found that knockdown of this mutant p53 reduced cell viability and exerted antitumor activity equivalent to high doses of several chemotherapeutic agents. The researchers
