The deletion of DYNLL1 was reported to result in increased chemoresistance in BRCA1-mutant HGSOC cells. Considering its role in chemoresistance, a better understanding of DYNLL1 expression is needed to develop novel strategies in the treatment of ovarian cancer. In the current study, we aimed to investigate differential expression of DYNLL1 in ovarian cancer with respect to cell types, chemosensitivity profiles, certain drug treatments and cancer progression. DYNLL1 levels were analyzed using expression profiling datasets from GEO and qRT-PCR in R. We found that the level of DYNLL1 was higher in ovarian cancer histotypes compared to normal ovarian cells. Selleck SP-2577 DYNLL1 expression is decreased in ovarian cancer cells of epithelial type; but, it is increased in ovarian cancer cells of stromal type, compared to matched control cells. Chemoresistant OC cells were shown to have lower DYNLL1 expression than chemosensitive OC cells. Carboplatin and NSC319726 treatments resulted in slightly decreased DYNLL1 expression and DYNLL1 levels were decreased in the course of cancer progression in ovarian cancer epithelial cells. The results suggest that changes in DYNLL1 expression in ovarian cancer might be cell-type dependent and lower DYNLL1 levels may be associated with increased chemoresistance in ovarian cancer. Although further studies are needed, certain drugs and cancer progression may lead to lower DYNLL1 levels, possibly resulting in increased chemoresistance. Therefore, it can be stated that DYNLL1 might be an important player in ovarian cancer progression and chemoresistance. This article is protected by copyright. All rights reserved.

Given the distinct biologic characteristics of upper tract urothelial carcinoma (UTUC) and urothelial carcinoma of the bladder (UCB), the authors examined whether infigratinib had varying activity in these settings. METHODS Eligible patients had metastatic urothelial carcinoma with activating FGFR3 mutations and/or fusions. Comprehensive genomic profiling was performed on formalin-fixed, paraffin-embedded tissues. Blood was collected for cell-free DNA analysis using a 600-gene panel. Patients received infigratinib at a dose of 125 mg orally daily (3 weeks on/1 week off) until disease progression or intolerable toxicity occurred. The overall response rate (ORR; partial response [PR] plus complete response [CR]) and disease control rate (DCR; CR plus PR plus stable disease [SD]) were characterized. RESULTS A total of 67 patients were enrolled; the majority (70.1%) had received ≥2 prior antineoplastic therapies. In 8 patients with UTUC, 1 CR and 3 PRs were observed (ORR, 50%); the remaining patients achieved a best response of SD (DCR, 100%). In patients with UCB, 13 PRs were observed (ORR, 22%), and 22 patients had a best response of SD (DCR, 59.3%). Notable differences in genomic alterations between patients with UTUC and those with UCB included higher frequencies of FGFR3-TACC3 fusions (12.5% vs 6.8%) and FGFR3 R248C mutations (50% vs 11.9%), and a lower frequency of FGFR3 S249C mutations (37.5% vs 59.3%). CONCLUSIONS Differences in the cumulative genomic profile were observed between patients with UTUC and those with UCB in the current FGFR3-restricted experience, underscoring the distinct biology of these diseases. These results support a planned phase 3 adjuvant study predominantly performed in this population. © 2020 American Cancer Society.Children generally favor individuals in their own group over others, but it is unclear which dimensions of the out-group affect this bias. This issue was investigated among 7- to 8-year-old and 11- to 12-year-old Iranian children (N = 71). Participants evaluated in-group members and three different out-groups Iranian children from another school, Arab children, and children from the United States. Children's evaluations closely aligned with the perceived social status of the groups, with Americans viewed as positively as in-group members and Arabs viewed negatively. These patterns were evident on measures of affiliation, trust, and loyalty. These findings, which provide some of the first insights into the social cognition of Iranian children, point to the role of social status in the formation of intergroup attitudes. © 2020 Society for Research in Child Development.The present exploratory study explored the trajectories and implications of at-home (military unaffiliated) parents' perceptions of youth's sibling relationships across the course of a parent's military deployment. Participants included 109 families with at least two siblings (older sibling and younger siblings age M = 10.85, SD = 3.92 and M = 7.89, SD = 3.58, respectively) and one parent serving in the National Guard. Data were collected via in-home interviews, at six time points across the deployment cycle. A series of multilevel models revealed increases in sibling disharmony during the months a deployed parent was away, but showed signs of recovery in the year after they returned. Increases in sibling disharmony were positively associated with increases in youth's externalizing behaviors above and beyond the effects of parenting. © 2020 Society for Research in Child Development.Plants have evolved light signaling mechanisms to optimally adapt developmental patterns to the ambient light environments. CONSTITUTIVE PHOTOMORPHOGENIC1 (COP1) and LONG HYPOCOTYL5 (HY5) are two critical components in the light signaling pathway in Arabidopsis thaliana. COP1 acts as an E3 ubiquitin ligase that targets positive regulators, such as HY5, leading to their degradation in darkness. However, functional analysis of the COP1-HY5 module in maize (Zea mays) has not been reported. Here, we investigated the expression patterns and roles of the COP1 and HY5 orthologs, ZmCOP1 and ZmHY5, in regulating photomorphogenesis. These two genes have high amino acid identities with their Arabidopsis homolog and were both regulated by light. Subcellular localization assay showed that ZmCOP1 was distributed in the cytosol and ZmHY5 localized in the nucleus. Exogenous expression of ZmCOP1 rescued the physiological defects of the cop1-4 mutant, and expression of ZmHY5 complemented the long hypocotyl phenotype of the hy5-215 mutant in Arabidopsis.
