Is Displaced Nuclear DNA a Meaningful Cause of Chronic Inflammation in Aging?

Sterile inflammation arises without external cause, such as infection or injury, and chronic sterile inflammation is a characteristic of aging. Inflammatory signaling becomes constant and pronounced in tissues, and the immune system is constantly roused to action. Processes, such as regeneration from injury, that depend upon a clear cycle of inflammation that starts, progresses, and resolves are significantly disrupted. It is no exaggeration to say that the downstream consequences of chronic inflammation accelerate the progression of all of the common age-related conditions. It is of great importance in atherosclerosis and neurodegenerative conditions, for example. Like raised blood pressure, chronic inflammation is one of the more important mechanisms acting to convert the low-level molecular damage at the root of aging into the various proximate causes of age-related disease and mortality. Thus the research community is greatly interested in understanding how and why sterile inflammation arises in later life. Cellular senescence is one sizable area of investigation, as senescent cells accumulate with age, and secrete inflammatory signals. Additionally, visceral fat tissue acts to increase the pace at which senescent cells arise, but also contributes to inflammation via other mechanisms. In the short open access commentary here, the authors discuss a potential mechanism whereby cells in aged tissues start to eject DNA fragments from the cell nucleus, and this can caus...

CONCLUSIONS: Considering the age group in which rectal prolapse is most commonly seen, and the change in bowel habits, chronic constipation and irritation chronic seen in rectal prolapse may be responsible for the development of rectum cancer, therefore endoscopic screening should not be overlooked in rectal prolapse cases.

CONCLUSION: The etiology of chronic groin pain post hernia repair is related in part to nerve injury. This is supported by the high frequency of sensory symptoms and numbness in these patients. However other factors including the role of tissue injury and inflammatory postoperative changes need to be considered.

The objective of this paper is to synthesise current knowledge on ALK rearrangement and its impact on the management of advanced NSCLC. Several inhibitors of the tyrosine kinase of ALK (crizotinib, ceritinib, alectinib) have been approved as first line therapies in patients with advanced ALK positive NSCLC, which are associated with a better median progression-free survival than conventional chemotherapy. Unfortunately, the emergence of drug resistance leads to tumor progression. In patients with oligoprogressive disease if local ablative therapy can be effected, continuing with the same ALK tyrosine kinase inhibitor is on...

Publication date: Available online 15 November 2019Source: Biotechnology ReportsAuthor(s): Pradeep Kumar, Balwant Singh, Vikram Thakur, Abhishek Thakur, Nandita Thakur, Deepak Pandey, Duni ChandAbstractTaxol® (generic name Paclitaxel) is a chemotherapeutic drug, effective against head, neck, breast, lung, bladder, ovary, and cervix cancers. Rising demands in chemotherapy and limited supply of natural taxol have ultimately increased the cost of the drug. Semi synthesis using taxol precursors is not able to meet the global supply and has intensified the need to find alternative ways of taxol production. In the present st...

Authors: Yang JD, Ma L, Zhu Z Abstract We assessed the expression of Serpin Family E Member 1 (SERPINE1) and its prognostic values in gastric adenocarcinoma (GAC) by using the data from TCGA database. The biological functions of SERPINE1 in GAC cells were detected by cell counting Kit-8, colony-forming, Transwell, and wound-healing assays, appropriately. Relative mRNA and protein levels were detected by RT-qPCR and western blot. Bioinformatics analysis indicated that SERPINE1 was significantly up-regulated in GAC tissues compared to normal tissues. High SERPINE1 expression led to a short overall survival and could ...
