In this study, the enhanced mice live somewhat longer than their unmodified peers, though not as much longer as is the case for the application of telomerase gene therapy. The mice do also exhibit reduced cancer risk, however. The scientists here class telomere shortening as a cause of aging, which is not a point universally agreed upon. Reductions in average telomere length in tissues looks much more like a downstream consequence of reduced stem cell activity than an independent mechanism. Researchers obtain the first mice born with hyper-long telomeres and show that it is possible to extend life without any genetic modification Given the relationship between telomeres and ageing - telomeres shorten throughout life, so older organisms have shorter telomeres - scientists launched a study generating mice in which 100% of their cells had hyper-long telomeres. The findings show only positive consequences: the animals with hyper-long telomeres live longer in better health, free from cancer and obesity. "This finding supports the idea that, when it comes to determining longevity, genes are not the only thing to consider. There is margin for extending life without altering the genes". Telomeres form the end of chromosomes, in the nucleus of each cell in the body. Their function is to protect the integrity of the genetic information in DNA. Whenever the cells divide the telomeres, they are shortened a little, so one of the main characteristics of age...

While other health care providers were reporting losses of hundreds of thousands of dollars a day as patients stayed away from hospitals, the cancer treatment provider reported its best financial year.
CONCLUSION: Our data suggested that combined therapy with monensin might be a useful strategy for preventing EMT-mediated acquired drug resistance. PMID: 32736704 [PubMed - as supplied by publisher]
A mutation found in esophageal cancer alters integrin β4 mRNA splicing. Biochem Biophys Res Commun. 2020 Aug 27;529(3):726-732 Authors: Kelly GT, Faraj R, Dai Z, Cress AE, Wang T Abstract Integrin β4 (CD104, mRNA: ITGβ4) contributes to anchoring cells to the extracellular matrix and is regulated in many cancer types where it contributes to tumor progression. One splice variant, integrin β4E, is poorly characterized. We extracted several mutations from tumor samples within ITGB4 near the splice site that controls ITGβ4E production, and computational analysis predicted six of th...
This study aimed to reveal whether and how GLN would modulate FGF21 production in relation to metabolism. With in vivo model of normal diet (ND) and high-fat diet (HFD) mice receiving GLN injection and in vitro model of mouse AML12 liver cells and differentiated 3T3L1 adipocytes challenged with GLN, GLN appeared to improve the glucose metabolism in HFD and ND mice and to elevate FGF21 protein expression in HFD liver and to increase both FGF21 protein and mRNA levels in WAT from HFD and ND mice and it also upregulated FGF21 expression in both AML12 and differentiated 3T3L1 cells. By using inhibitors against variou...
This study aimed to investigate the stability and therapeutic efficacy of the modified LNA- and PNA-type anti-miRs in a murine prostate cancer model under various treatment conditions. After verifying the anti-cancer potential of anti-miR21 by targeting tumor suppressor PTEN, the potential of the modified LNA- and PNA-type anti-miR21s was compared in vitro and in vivo. We found that PNA-type anti-miR21 showed better stability and therapeutic efficacy in the xenografted mouse tumor model than the LNA-type anti-miR21. Furthermore, PNA-type anti-miR21 treatment showed reduced tumor metastasis. This study may serve a...
In conclusion, five different imatinib-resistant GIST cell lines including the EXOC2-AK7 fusion gene derived from GIST-R5 represent important research tools for the investigation of cancer cell mechanisms underlying drug resistance and genetic variation. Furthermore, our study may facilitate pre-clinical studies of new therapeutic strategies. PMID: 32736695 [PubMed - as supplied by publisher]
In this study, we showed that hyper-O-GlcNAcylation reduced the expression of myogenin, a transcription factor critical for terminal muscle development, in C2C12 myoblasts differentiation by O-GlcNAcylation on Thr9 of myocyte-specific enhancer factor 2c. Furthermore, we showed that O-GlcNAcylation on Mef2c inhibited its DNA binding affinity to myogenin promoter. Taken together, we demonstrated that hyper-O-GlcNAcylation attenuates skeletal muscle differentiation by increased O-GlcNAcylation on Mef2c, which downregulates its DNA binding affinity.
