In conclusion, we show here that sEVs are responsible for mediating paracrine senescence and speculate that they could be involved in inducing bystander senescence during therapy-induced senescence or aging. In fact, when compared to soluble factors, sEVs have different biophysical and biochemical properties as they have a longer lifespan than do soluble factors and they are more resistant to protease degradation. The idea that blocking sEV secretion could be a potential therapeutic approach to alleviate senescence "spreading" during chemotherapy-induced senescence or in aging tissues presents itself as a very attractive tool for the future. Telomere Dynamics with Age are Very Different Between Mammalian Species https://www.fightaging.org/archives/2019/07/telomere-dynamics-with-age-are-very-different-between-mammalian-species/ Telomeres are caps of repeated DNA sequences at the ends of chromosomes. They shorten with each cell division, a part of the mechanism that ensures somatic cells can only replicate a limited number of times. Telomerase acts to lengthen telomeres, and in humans telomerase is only active in stem cells. Thus our cells exist in a two-tier system, in which only tiny populations of privileged stem cells are permitted unrestricted replication, while the vast majority of somatic cells are limited. Matters are similar across all higher animals, and this state of affairs likely evolved because it keeps cancer to a low enough level, an...

CONCLUSION: This first randomized resistance training trial in pancreatic cancer patients indicated clinically relevant improve- ments in QoL after 3 but not after 6 months. Given the severity of pancreatic cancer, exercise recommendations may already commence at surgery. PMID: 31431236 [PubMed - in process]

Publication date: 15 December 2019Source: Journal of Molecular Structure, Volume 1198Author(s): Lei Wang, Gui-Bin XueAbstractSolvothermal reactions of 1, 3, 5-tris (4-carboxyphenyl)-benzene (H3BTB) with Gd(NO3)·6H2O gave rise to a new highly porous coordination polymer {[Gd(BTB)(H2O)](DMF)(H2O)}n (1) having three dimensional structure. In light of its highly rigid framework as well as the large one-dimensional triangular channel configuration that has abundant open metal sites, we can utilize the resulting activated 1a as effective Lewis catalysts for the acetaldehyde's cyanosilylation at room temperature. The compa...

Hubert JoeAbstractCo(II), Ni(II), Cu(II) and Zn(II) complexes of Schiff base ligand (thio-L-his) derived from thiophene-2-carboxaldehyde (thio) with l-histidine (L-his) were synthesised. The thio-L-his and its metal complexes have been optimized and quantum chemical parameters are calculated using density functional theory. Despite several donor sites in the synthesised thio-L-his, the coordination with metal ion occurred through azomethine nitrogen and carboxylate oxygen as eviden...

Despite the great advances in chemotherapy, there is still no certain medical treatment for cancer. During this investigation, a novel 2,5-diketopiperazine derivative 3(R),6(S)-bis (4-hydroxy phenyl)-piperazine-2,5-dione: (BHPPD) was designed, synthesized, and evaluated.

In this study, we performed RNA-sequencing analysis of MCF10A cells and identified 1166 genes that were upregulated and 861 genes that were downregulated by TGF-β. Gene set enrichment analysis revealed that focal adhesion and metabolic pathways were the top enriched pathways of the up- and downregulated genes, respectively. Genes in these pathways also possess significant predictive value for renal cancers. Moreover, we confirmed that TGF-β induced expression of MICAL1 and 2, and the histone demethylase, KDM7A, and revealed their regulatory roles on TGF-β-induced cell migration. We also show a critical effec...

IAPs are proteins with antiapoptotic abilities, and their functions are different from the Bcl-2 (B-cell lymphoma-2) family proteins. However, the precise role of Livin in colon cancer progression remains unclear. The purpose of this study is to assess the effect of overexpression Livin in colon cancer cells and to examine its molecular mechanism. We demonstrated that Livin induced a colon cancer phen...

This study investigated the effect of the dietary supplementation of bovine lactoferrin (LF) on growth performance, hematological and immunological parameters, antioxidant enzymes activity and disease resistance against Vibrio harveyi in yellowfin sea bream (Acanthopagrus latus) fingerling. The fish with initial body weight 10 ± 0.3 g were randomly distributed at 10 fish per each 250 L fiberglass tank, and fed with four experimental diets (a control basal diet and three supplemented diets with 400, 800 and 1200 mg LF kg−1 diet) for 8 weeks. The obtained results showed that fish fed with LF suppleme...

CanalAbstractHorses are often used as blood donors for commercial horse serum (HS) production and to manufacture biologicals. HS is an alternative for fetal bovine serum (FBS) used as a supplement for cell culture and vaccine production. Furthermore, HS is also frequently obtained in order to produce antisera toxins and pathogens. The advent of high-throughput sequencing (HTS) has promoted changes in virus detection, since previous k...
