Abstract: XRCC4 and XLF are structurally related proteins important for DNA Ligase IV function. XRCC4 forms a tight complex with DNA Ligase IV while XLF interacts directly with XRCC4. Both XRCC4 and XLF form homodimers that can polymerize as heterotypic filaments independently of DNA Ligase IV. Emerging structural and in vitro biochemical data suggest that XRCC4 and XLF together generate a filamentous structure that promotes bridging between DNA molecules. Here, we show that ablating XRCC4's affinity for XLF results in DNA repair deficits including a surprising deficit in VDJ coding, but not signal end joining. These data are consistent with a model whereby XRCC4/XLF complexes hold DNA ends together--stringently required for coding end joining, but dispensable for signal end joining. Finally, DNA-PK phosphorylation of XRCC4/XLF complexes disrupt DNA bridging in vitro, suggesting a regulatory role for DNA-PK's phosphorylation of XRCC4/XLF complexes..

Abstract: Disadvantaged family socioeconomic status (SES) is often assumed to diminish parent training program effectiveness. In examining effects of SES, influences of initial problem severity have been largely ignored. In the present meta-analysis, we examined (a) whether there is a differential influence of SES on parent training effectiveness at immediate posttreatment and at 1-year follow-up-controlling for levels of initial problem severity--and (b) whether SES interacts with initial problem severity in its effect on program effectiveness. Seventy-five studies on parent training program effectiveness to reduce disruptive child behavior were included. Separate analyses were conducted for immediate posttreatment and approximately 1-year follow-up assessments. Immediately posttreatment, disadvantaged samples benefited less from parent training, but only when they had low levels of initial problem severity. At follow-up, disadvantaged samples benefited less from parent training regardless of initial problem severity. Initial problem severity was a strong predictor of effect sizes both immediately posttreatment and at follow-up. Parent training programs are equally effective for disadvantaged and nondisadvantaged families immediately posttreatment, at least when initial problems are severe. Maintenance of treatment gain, however, seems harder for disadvantaged families, suggesting that more sustained family support may be needed.. Title: Does socioeconomic status matter?

Abstract: Sloan-Kettering virus gene product (Ski) is an unique nuclear pro-oncoprotein and belongs to the ski/sno proto-oncogene family. Ski plays multiple roles in a variety of cell types, it can induce both oncogenic transformation and terminal muscle differentiation when expressed at high levels. Ski/SnoN are important transcription regulators of the transforming growth factor- (TGF-) superfamily and function mainly through heterodimers. Since TGF- superfamily are key regulators of follicle development and it has been previously shown that SnoN is also vital to follicle development, this research was conducted to clarify the relationship between Ski expression and mouse follicular development, in ovaries of neonatal and gonadotropin-induced immature mice by immunohistochemical and real-time PCR techniques. In postnatal mice, positive staining for Ski was highly detected in oocyte nuclei at postnatal day 1. With follicular development, the localization moved gradually from oocyte nuclei to perinuclear space and the total levels decreased. During the estrous cycle, Ski expression was apparent at proestrus and estrus, faint at metestrus, highest at diestrus. After injection of gonadotropin, Ski was found in perinuclear space and weak in oocyte nuclei. Following the initiation of luteinization, the expression of Ski was found in corpus luteum. Real-time PCR results also showed that Ski mRNA expression was opposite to ovulation-related genes during the cumulus expansion, with the development of the follicles, its expression level decreased. Ski is expressed in a specific manner during follicle development, ovulation and luteinization. So Ski might play essential roles in these processes especially during early follicular development..
