AI Article Synopsis

  • Previous research suggests that environmental factors may account for 70% to 90% of cancer cases, highlighting the significance of these extrinsic elements in cancer development.
  • Many cancer patients and survivors tend to remain in the same neighborhoods where they lived before their diagnosis, which means they continue to be exposed to potential carcinogens.
  • This commentary reviews existing studies linking particulate matter (PM) with cancer mortality and post-treatment health issues, and it calls for more research to explore these important connections.

Article Abstract

Previous studies of the environment and cancer have focused on etiology, showing that extrinsic factors in the environment contribute to 70% to 90% of cancers. Cancer patients and survivors often continue to live in the same neighborhoods they resided in before their cancer diagnosis. Thus, patients and survivors are exposed to the same environmental contexts that likely contributed to their original cancer, but little is known about the health effects of continued exposure to carcinogens after a cancer diagnosis. This commentary provides a summary of studies of the association between PM and cancer mortality among patients and PM and posttreatment morbidity among cancer survivors, and proposes new directions and opportunities for future research on such topics.

Objective And Significance: Transforming growth factor-beta (TGF-β) plays a pivotal role in breast development by modulating tissue composition during the developmental phase. The TGFβ type II receptor (TGFβ RII) is implicated in breast cancer and represents a valuable therapeutic target. Due to the off-target side effects of many existing TGFβI/TGFβ RII inhibitors, a more targeted approach to drug discovery is necessary.

Background: Solid organ transplantation (SOT) is vital for end-stage organ failure but faces challenges like organ shortage and rejection. Artificial intelligence (AI) offers potential to improve outcomes through better matching, success prediction, and automation. However, the evolution of AI in SOT research remains underexplored.

EGFR inhibitors are a class of targeted therapies utilized in the management of certain tumor kinds such as NSCLC and breast cancer. Series of 1,2,3-triazole-Schiff's base hybrids were designed, synthesized, and estimated for their antitumor effect toward breast cancer cells, MCF-7 and MDA-MB-231. The safety and selectivity of the new compounds were tested using normal cell (WI-38).
