DICP researchers and their collaborators have uncovered new mechanisms by how fructose inhibits the polarization of M1-type tumor-associated macrophages (M1-like TAMs), thereby promoting colorectal cancer development.

A Cancer Research UK-funded trial is giving participants resveratrol as a potential prevention drug for bowel cancer. Resveratrol is a chemical mostly found in red grapes and products made from these grapes, such as wine and juice. Previous lab studies have shown that low doses of purified resveratrol can reach the bowel undigested and inhibit bowel cancer growth.

The University of Texas MD Anderson Cancer Center’s Research Highlights showcases the latest breakthroughs in cancer care, research and prevention.

A Michigan State University researcher’s new model for studying breast cancer could help scientists better understand why and where cancer metastasizes.

 

Gastrointestinal endoscopy has undergone significant transformation since its first introduction in the early 20^th century. Despite advances in modern endoscopy, its precision in detecting and removing colorectal cancer (CRC) varies; colorectal polyps or cancer are still missed in 2.1-5.9% of cases. Additionally, post-colonoscopy CRC occurs in 30% of patients who have undergone incomplete polyp resection. When biopsies are taken, only 11.4% are found to be malignant, rendering 88.6% of tissue removal unnecessary. To address these shortcomings, modern endoscopy is evolving. Current endoscopic modalities include wide-field and microscopic-field endoscopy. Wide-field view endoscopy remains the most frequently used type and includes the current standard of practice—white light endoscopy—as well as other modalities such as virtual and dye-based chromoendoscopy, ultrathin endoscopy, and capsule endoscopy. Microscopic field endoscopy encompasses several new emerging modalities that can provide microscopic resolution capable of diagnosing lesions in vivo (optical biopsy), thus reducing the number of unnecessary biopsies. However, the emerging technology comes with a learning curve and requires time for endoscopists to master and achieve interobserver agreement. Consequently, there is a growing opportunity to develop machine learning technology to assist with the learning process. We review current modalities available for the diagnosis of CRC, including the current standard of practice, new enhanced imaging modalities, and optical biopsy.

Cancer is thought to be the second most prevalent and leading cause of mortality worldwide, affecting both men and women among other chronic diseases. While there are several treatment options available, significant strains, side effects, and resistance have led researchers to focus on finding novel alternative medications for cancer treatment. Antioxidants and the immunomodulatory activities of medicinal plants are studied and considered to have anti-cancer effects. Medicinal plants contain diverse phytoconstituents as natural drugs, which possess numerous medicinal properties used for treating and preventing various illnesses. These phytoconstituents work through several mechanisms to target and kill cancer cells. Anticancer mechanisms include suppression and arrest of the G0/G1 phase, acting as anti-mitotic and anti-microtubule agents, enhancing the activity of macrophages, inhibiting cancer cells through various signaling cascades, anti-angiogenesis, and cytotoxicity. Investigating botanical sources and their metabolites can uncover new chemical entities for cancer treatment at the molecular target level and provide future interventions in cancer therapy. This article summarizes a few medicinal plants and their mechanisms of action for their anticancer potential. Furthermore, we discuss the future prospects and limitations of using medicinal plants in cancer treatment.
