Oncotarget: экспрессия PD-1 / PD-L1 в плоскоклеточных интраэпителиальных поражениях заднего прохода

Oncotarget недавно опубликовал « Экспрессию PD-1 / PD-L1 в плоскоклеточных интраэпителиальных поражениях заднего прохода », в котором сообщалось, что оценивали наличие и распределение лимфоцитов CD8, а также присутствие лимфоцитов PD-1 и эпителиальных клеток PD-L1. Лимфоциты CD8 чаще наблюдались в HSIL по сравнению с LSIL в собственной пластинке или внутриэпителиальном слое. Лимфоциты PD-1 наблюдались чаще при HSIL по сравнению с LSIL. Не было разницы между HSIL и LSIL для эпителиальных клеток PD-L1. Анальные диспластические поражения сопровождаются воспалительным лимфоцитарным инфильтратом, экспрессирующим CD8 и PD-1, что чаще встречается при поражениях высокой степени. Доктор Марго Букау из Hôpital Bichat-Claude Bernard сказала: « Анальная интраэпителиальная неоплазия (AIN) является предшественником плоскоклеточного рака заднего прохода (ASCC) ».

Metabolism of Breast Cancer Cells Exploited by Amino Acids

Researchers from Germany starved breast cancer cells of amino acids, including methionine, and exploited their dependency on the amino acid transporter SLC6A14. 3D Illustration of a chain of amino acids 3D Illustration of a chain of amino acids Cancerous tumors are greedy invaders. In order to sustain their signature high rate of growth, proliferation, and to increase their metabolic capacity, tumor cells demand more nutrients from the body, such as glucose and amino acids. One way that tumor cells elevate this intake of nutrients is by increasing the expression of genes that encode amino acid transporters. This knowledge provided new potential therapeutic targets for the authors of the cover paper for Oncotarget’s Vol 11, Issue #48. oncotarget impact factor “Targeting tumor metabolism has been explored as a strategy to inhibit tumor growth and proliferation due to the elevated metabolic requirements of cancer cells compared to their normal counterparts [1].” Researchers from Ger...

Trending with Impact: Vitamin D Potential Use in BRCA1 Ovarian Cancer

In carriers of the BRCA1 gene mutation, researchers have found vitamin D biosynthesis and signaling to be impaired. This study provides a viable reason to explore the potential use of vitamin D in treatments to prevent ovarian cancer in women with the BRCA1 mutation. The Trending with Impact series highlights Oncotarget publications attracting higher visibility among readers around the world online, in the news, and on social media—beyond normal readership levels.

Twitter Oncotarget Listen to an audio version of this article At this point in time, there is only one nutrient in the human body that can be generated via exposure to sunlight. Vitamin D is not only biologically produced by UV light; it can also be metabolized by eating oily fish, such as salmon and tuna, mushrooms, eggs, dairy products, and other vitamin D fortified foods and supplements. In additio...
