RNA silencing is an evolutionarily conserved system that functions as an antiviral mechanism in higher plants and insects. To counteract RNA silencing, viruses express silencing suppressors that interfere with both siRNA- and microRNA-guided silencing pathways. We used comparative in vitro and in vivo approaches to analyse the molecular mechanism of suppression by three well-studied silencing s...

The Caenorhabditis elegans pRb ortholog, LIN-35, functions in a wide range of cellular and developmental processes. This includes a role of LIN-35 in nutrient utilization by the intestine, which it carries out redundantly with SLR-2, a zinc-finger protein. This and other redundant functions of LIN-35 were identified in genetic screens for mutations that display synthetic phenotypes in conjuncti...

K e y w o r d s Leukemia, Integro-differential equations, Nonlinear dynamics. 1. I N T R O D U C T I O N Cancer has become the second-ranking cause of death in the Western world. There is a growing interest in cancer research. One of the main topics is the interaction between the immune system and cancer. The model which we propose describes the interactions between a single cell cancer and the...

BACKGROUND Wharton's jelly derived stem cells (WJMSCs) are gaining attention as a possible clinical alternative to bone marrow derived mesenchymal stem cells (BMMSCs) owing to better accessibility, higher expansion potential and low immunogenicity. Usage of allogenic mesenchymal stem cells (MSC) could be permissible in vivo only if they retain their immune properties in an inflammatory setting....

Tumor suppressors refer to a large group of molecules that are capable of controlling cell division, promoting apoptosis, and suppressing metastasis. The loss of function for a tumor suppressor may lead to cancer due to uncontrolled cell division. Because of their importance, extensive studies have been undertaken to understand the different functional mechanisms of tumor suppressors. Here, we ...

The features of the rehabilitation immune system piglets after weaning were studied in connection with different seasons farrowing. To fulfill this goal, 4 groups formed from offspring sows SM-1 breed Novosibirsk selection. 1st group included winter farrowings, and 2nd, 3rd 4th groups, respectively, young animals born spring, summer autumn. Each consisted 30 animals. Studies indicators status c...

Correlated predictors in regression models are a fact of life in applied social science research. The extent to which they are correlated will influence the estimates and statistics associated with the other variables they are modeled along with. These effects, for example, may include enhanced regression coefficients for the other variables—a situation that may suggest the presence of a suppre...

CtBP1 and CtBP2 are closely related and evolutionarily conserved transcriptional corepressors. There is strong evidence linking CtBPs to tumorigenesis and tumor progression. CtBPs promote epithelial-mesenchymal transition and function as apoptosis antagonists. Also, CtBPs mediate repression of several tumor suppressor genes. Certain tumor suppressors also target CtBPs to restrain their tumor-pr...
