Exploring the interaction between cell death and cellular senescence in cancer

-

 


Aging cells secrete substances known to promote the growth of cancer cells. The development of drugs that can selectively kill these cells or inhibit the secretion of substances is ongoing. The latest findings on the interaction between cell death and cellular senescence in cancer and their pathophysiological significance have been reviewed by a team from Osaka Metropolitan University's Graduate School of Medicine and Harvard Medical School.

Lecturer Kouhei Shimizu and Professor Fuminori Tokunaga of OMU and Dr. Hiroyuki Inuzuka of Harvard Medical School outlined the molecular mechanisms of various types of cell death and the changes in their regulatory factors that occur with age.

Since senescent cells often have resistance to apoptosis, the best characterized programmed cell death, the removal of this resistance has been a major goal of senescent cell removal therapy. On the other hand, it is not yet known how the relatively new types of inflammatory programmed cell death, such as necroptosis, pyroptosis, and ferroptosis, the molecular mechanisms of which have been rapidly elucidated in recent years, are regulated in senescent cells.

There are also many questions about whether therapies such as senescent cell removal therapy and senomorphics-drugs that only target the harmful senescence-associated secretory phenotype without killing the senescent cells-can be applied to these new types of programmed cell death, and there is little understanding of these either.

Avoiding prostate cancer screening increases risk of death

  Men who consistently avoid prostate cancer screening appointments face a disproportionately higher risk of dying from the disease, finds research identifying a new high-risk group. An analysis of data from across seven countries from the world's largest prostate cancer screening study, the European Randomized study of Screening for Prostate Cancer (ERSPC), is presented this weekend at the European Association of Urology (EAU) Congress in Madrid. Prostate cancer is the most common form of cancer in men in 112 countries, with prevalence expected to double by 2040. If introduced on a national scale, prostate cancer screening programmes that measure levels of prostate-specific antigen (PSA) in the blood have the potential to give men earlier access to treatment, a better chance of being cured. They can also prevent costly treatment associated with advanced prostate cancer. Long-term follow-up data from the ERSPC consistently report that PSA screening programmes can lead to a 20% re...

EchoBack CAR T-cells could be a game changer in cancer immunotherapy

  Imagine a super-charged immune cell that can launch a focused attack on stubborn solid tumors - a smart fighter that destroys cancer cells for days without tiring. USC biomedical engineers have made this concept a reality, crafting what they have named the "EchoBack CAR T-cell," which could soon be a game changer in the field of cancer immunotherapy . The work, published in the scientific journal Cell, is a groundbreaking new approach that could overcome major obstacles in treating tumors that are not usually candidates for immunotherapy, while keeping healthy tissue safe. Chimeric antigen receptor (CAR) T-cell therapy is a promising field of cancer treatment that has shown great success in treating bloodborne cancers such as leukemia. It is a highly customized therapy in which cancer-fighting T-cells are drawn directly from the blood of a patient and given genetic modifications to enhance their ability to target and kill cancerous cells. The USC Alfred E. Mann Department ...

The Role of Analytical Chemistry in Industry and Manufacturing

-

Industry and the manufacturing sector use multiple analytical chemical methods, whether for new product development, processing, or quality control. This article outlines the research to be presented at Pittcon on the advances being made in analytical chemistry and their application in industry and manufacturing. Spectroscopy is a valuable analytical tool for a wide range of sectors. Several talks will focus on Raman spectroscopy as a highly versatile analytical tool, which can be used in chemical processing from laboratory to manufacturing. Raman spectroscopy’s use in polymer science to measure and control chemical processes is a particular focus. The technique is becoming increasingly relevant as chemical manufacturing expands to include new developments such as batch reactions, microreactors, flow synthesis, and continuous processes. Pittcon will hear examples of using Raman spectroscopy to improve process efficiency and predict reaction end-times and physical properties of chemical...
