AI Article Synopsis

  • The study aimed to define the immune profile of colon cancer cells, specifically the HR8348 cell line.
  • Researchers used 40 different monoclonal antibodies and flow cytometry to analyze the expression of various immune markers on these cells.
  • The results showed that while HR8348 lacked several common immune markers, it did express some specific ones, indicating shared characteristics with certain types of white blood cells.

Article Abstract

Objective: To define the immune phenotype of colon cancer cells.

Methods: Using a panel of 40 anti-human monoclonal antibodies (MoAbs), the cells of colon cancer HR8348 were analyzed with three-color flow cytometry after direct immunofluorescent staining.

Results: HR8348 cell line did not express CD2, CD3, CD4, CD5, CD7, CD8, TCR, CD10, CD11b, CD14, CD16, CD19, CD22, CD25, CD28, SmIg, CD33, CD35, CD36, CD41a, CD45, CD45RA, CD45RO, CD56, CD61, CD64, CD66b, CD69, CD71, CD117, CD122 and P-glycoprotein but expressed CD13, CD15, CD20, CD38, CD95 and HLA-DR.

Conclusion: The results demonstrate that colon cancer cell line HR8348 shares some antigenic determinants with leucocyte lineage.

The redox imbalance, caused by depletion or generation of reactive oxygen species (ROS), is a key mechanism by which metal complexes exert anticancer effects. Carbidopa has shown the ability to inhibit the MDA-MB-231 cell line, a highly aggressive triple-negative human breast adenocarcinoma, by inducing reductive stress. The metal complex of carbidopa with zinc (ZnCarbi) was designed to modify carbidopa's structure and exhibited increased cytotoxicity against MDA-MB-231 cells.

Background: Reduced-port laparoscopic surgery (RPLS) uses the minimum possible number of ports or small-sized ports in laparoscopic surgery. The combination of RPLS and natural orifice specimen extraction (NOSE) minimizes the procedural damage.

Methods: A total of 17 patients diagnosed with right colon cancer were included: 5 patients in the RPLS + NOSE group and 12 patients in the conventional laparoscopic surgery (CL) + mini-laparotomy (ML) group.

Purpose: Human epidermal growth factor-2 (HER-2) targeted drugs are used in only HER-2 overexpressed cancers. However, only a small portion of these cancer types are HER-2 overexpressed. In this study, we aimed to upregulate HER-2 receptors in MCF-7 breast cancer and HT-29 colon cancer cell cultures, which these cells are not HER-2 upregulated in natural status.

Unlabelled: Many bacteria metabolize ethanolamine as a nutrient source through cytoplasmic organelles named bacterial microcompartments (BMCs). Here we investigated the molecular assembly, regulation, and function of BMCs in a Gram-negative oral pathobiont that is associated with adverse pregnancy outcomes. The genome harbors a conserved ethanolamine utilization () locus with 21 genes that encode several putative BMC shell proteins and a two-component signal transduction system (TCS), in addition to the enzymes for ethanolamine transport and catabolism.

Chemotherapy is one of the most widely used anticancer treatments worldwide. However, despite its clinical effectiveness, most chemotherapeutic agents are associated with severe side effects. To address this limitation, there is an urgent need for the development of novel anticancer agents.
