Genomic stability is critical for cell survival and its effective repair when damaged is a vital process for preserving genetic information. Failure to correctly repair the genome can lead to the accumulation of mutations that ultimately drives carcinogenesis. Life has evolved sophisticated surveillance, repair pathways, and mechanisms to recognize and mend genomic lesions to preserve its integrity. Many of these pathways involve a cascade of protein effectors that act to identify the type of damage, such as double-strand (ds) DNA breaks, propagate the damage signal, and recruit an array of other protein factors to resolve the damage without loss of genetic information. It is now becoming increasingly clear that there are a number of RNA processing factors, such as the transcriptional machinery, and microRNA biogenesis components, as well as RNA itself, that facilitate the repair of DNA damage. Here, some of the recent work unravelling the role of RNA in the DNA Damage Response (DDR), in particular the dsDNA break repair pathway, will be reviewed.Physical activity (PA) promotion remains a cornerstone of primary and secondary prevention efforts to reduce morbidity and mortality from cardiovascular disease (CVD). While frontline health care providers (HCPs; e.g., family physicians, cardiologists, registered nurses, nurse practitioners, etc.) are in an optimal position to administer PA-promoting interventions to their patients, many HCPs may feel ill-equipped to address common obstacles to implementing and maintaining complex health behavior change. Behavioral counseling refers to a collection of theory- and empirically-supported strategies and approaches to health behavior promotion that can be learned and applied by HCPs for CVD prevention and treatment. In this selective review, we discuss prominent theories of health behavior change and the empirical intervention literature regarding PA promotion in community and CVD-samples and provide practical recommendations for integrating effective behavioral counseling strategies to clinical practice for frontline HCPs. We argue that behavioral counseling interventions for PA can be effectively executed within the contextual constraints of health settings through subtle shifts in communication strategies and brief counseling approaches. The administration of behavioral counseling for PA by HCPs has enormous potential to reduce CVD incidence and progression at a population level.The prokaryotic CRISPR-Cas systems could be applied as revolutionized genome editing tool in live cells of various species to modify, visualize and identify definite sequences of DNA and RNA. CRISPR-Cas could edit the genome by homology-directed repair and non-homologous end joining mechanisms. Furthermore, DNA-targeting modification by CRISPR-Cas methodology provides opportunity for diagnosis, therapy and the genetic disorders investigation. Rapamycin purchase Here, we summarized delivery systems employed for CRISPR-Cas9 for genome editing. Then preclinical studies of the CRISPR-Cas9-based therapeutics will be discussed considering the associated challenges and developments in its translation to clinic for cancer therapy.
15-Hydroxy-8(17),13(E)-labdadiene-19-carboxylic acid (HLCA) isolated from Juniperus foetidissima, has been recently identified as an antiproliferative agent; however, the molecular basis of antiproliferative effects of HLCA remains unknown. To investigate it, the current study has emphasized the hypothesis that HLCA induced cell death is a consequence of intracellular reactive oxygen species (ROS) production followed by cell cycle arrest and apoptosis.

Human ovarian OVCAR-3 and Caov-4 cells were treated with various concentrations of HLCA (48h) and the measurement of intracellular ROS was considered. Then, the potential of HLCA in promoting apoptosis was investigated via flow cytometry, western blot, and caspase activity assay. Also, the inhibitory effect of HLCA on the cell cycle was evaluated using flow cytometry and western blot analysis.

We found intracellular (ROS) accumulation in HLCA-treated cells. Subsequent observation of the increment in pro-apoptotic Bax as well as the decrement in antiapoptotic Bcl2 revealed that the HLCA-induced cytotoxicity may be triggered by the intrinsic pathway of apoptosis. Our subsequent experiments suggested that caspase-9 and -3 were activated and led the cells to apoptosis during the process. Cell cycle disruption at the G1 phase via down-regulation of cyclin D1 and Cyclin-dependent kinase 4 (CDK4) was another proved mechanism by which HLCA exerts its antiproliferative effects on the ovarian cell lines, OVCAR-3 and Caov-4, especially at relatively lower concentrations.

This is the first study that reveals the apoptotic effects of HLCA, suggesting its therapeutic potential as an effective anti-tumor agent. However, further in vivo studies are required to confirm these effects.

Non-alcoholic fatty liver disease (NAFLD) is a common chronic liver disease and lacks for safe and effective drug to therapy completely. Ginsenoside-Rg1 is one of the main components of ginseng and has been proved to counteract a variety of diseases. However, there is currently a lack of sufficient evidence to support the efficacy of ginsenoside-Rg1 in the treatment of NAFLD. Our aim was to investigate whether Ginsenoside-Rg1 is a potential drug for NAFLD.

NAFLD model in rats was established by giving a high-fat diet (HFD), ginsenoside-Rg1 was intragastrically administered 100mg/kg/d for 8weeks in NAFLD rat. Serum biochemical indices were measured. Liver tissues were stained with hematoxylin and eosin (HE) and oil red O. Total RNA was extracted from liver and was used for high throughput sequencing to identify the changes of transcriptome. The relevant hub genes were verified by quantitative real-time PCR and western blot.

Serum biochemical analysis indicated that ginsenoside-Rg1 improved liver function.
