Mayo Clinic researchers develop more efficient system to reprogram stem cells

ROCHESTER, Minn. --?Induced pluripotent stem cells, the workhorse of many regenerative medicine projects, start out as differentiated cells that are reprogrammed to pluripotent stem cells by exposure to a complex set of genetic cocktails. Mayo researchers now report that using the measles virus vector; they've trimmed that multi-vector process with four reprogramming factors down to [...]

ConclusionsConsanguineous marriages account for a genetic “founder effect.” SCID is a pediatric emergency that dictates immediate precautions and curative treatment with HSCT. Due to lack of newborn screening for SCID within the Palestinian population, most patients in this cohort were diagnosed upon clinical symptoms, which led to a delayed diagnosis, harmful administration of contra-indicated live vaccines, delay in HSCT, and poor outcome.

Contributors : Adele Fielding ; Sarah ArefSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensThe mechanisms by which oncolytic vaccine strains of measles virus exert their tumor selectivity are not well elucidated.The goal of this study is to compare the gene expression profiles of MV-resistant MSC cell line (hTERT) and MV-susceptible MSC cell line (5H) before and after infection with MV (24 hours post infection)Through RNA-seq we were able to identify genes that are potentially contribute to the resistant phenotype of hTERT cells compared to their malignant counterparts, 5H cells.

Ott Research Institute of Obstetrics, Gynecology and Reproductology, Saint Petersburg, Russia 2Department of Genetics and Biotechnology, Saint Petersburg State University, Saint Petersburg, Russia In the present review, we focus on the phenomenon of chromothripsis, a new type of complex chromosomal rearrangements. We discuss the challenges of chromothripsis detection and its distinction from other chromoanagenesis events. Along with already known causes and mechanisms, we introdu...

Conclusions Apart West Nile virus (78), thousands of congenital microcephaly cases, fetal brain tissue damage and neurological syndromes have been associated with ZIKV infection. Unfortunately, the epidemics of this mosquito born, and a relative stable virus is on a rise. Although congenital microcephaly is a rare disorder however, due to lack of standardized diagnostic test facilities, the incidence in the geographically widespread ZIKV epidemic regions is higher. Animals studies showed that ZIKV is a neurotropic virus. It directly targets the developing embryonic brain cells by inducing apoptosis, cell-cycle arrest, and...

om RNA viruses have been subjected to substantial engineering efforts to support gene therapy applications and vaccine development. Typically, retroviruses, lentiviruses, alphaviruses, flaviviruses rhabdoviruses, measles viruses, Newcastle disease viruses, and picornaviruses have been employed as expression vectors for treatment of various diseases including different types of cancers, hemophilia, and infectious diseases. Moreover, vaccination with viral vectors has evaluated immunogenicity against infectious agents and protection against challenges with pathogenic organisms. Several preclinical studies in animal model...

In this study, we show that calorie restriction is protective against age-related increases in senescence and microglia activation and pro-inflammatory cytokine expression in an animal model of aging. Further, these protective effects mitigated age-related decline in neuroblast and neuronal production, and enhanced olfactory memory performance, a behavioral index of neurogenesis in the SVZ. Our results support the concept that calorie restriction might be an effective anti-aging intervention in the context of healthy brain aging. Greater Modest Activity in Late Life Correlates with Lower Incidence of Dementia ...
