RNA binding protein QKI contributes to WT1 mRNA and suppresses apoptosis in ST cells
Xin Liu,Jia Guo,Mengjiao Zhou,Yuwei Yang,Mengdi Liang,Chunyan Bai,Zhihui Zhao,Boxing Sun 한국유전학회 2017 Genes & Genomics Vol.39 No.9
The RNA binding protein quaking (QKI), a key member of the STAR family, as an upstream gene could involve in much process including cell proliferation, apoptosis, differentiation and so on. However, the roles of QKI in germ cell, especially in swine testis (ST) cells, was not clear currently. And apoptosis plays important roles in the growth and development. The purpose of the present study was to clarify the relationship between QKI and apoptosis in ST cells. Firstly, our results showed that pEF1α- QKI and shQKI3 have clear effects on expression levels of QKI. Secondly, we established that QKI directly binds to WT1 3′UTR by binding with QRE-1 (2046–2052 bp, ACT AAC ) only. Furthermore, QKI overexpression significantly increased the expression levels of WT1 and Bcl-2. QKI also has the effect on delaying the degradation of WT1 mRNA. In addition, we verified that QKI had a significantly suppressed apoptosis in ST cells. Finally, pBI-WT1 could make up for shQKI3-induced decrease in WT1, Bcl-2 mRNA levels and suppress apoptosis in ST cells. The results demonstrated that QKI was an important regulatory factor that affects apoptosis by targeting WT1 gene.

Background and Purpose A systematic review and meta-analysis was performed of the outcome of Coronavirus disease 2019 (COVID-19) infection in patients with multiple sclerosis (MS) who received disease-modifying therapies (DMTs). Methods Relevant studies published before November 2022 in the PubMed, Cochrane Library, Chinese National Knowledge Infrastructure, and Web of Science databases were retrieved using the following search expression: (“multiple sclerosis” OR “MS”) AND (“DMT” OR “disease modifying therapies”) AND (“COVID-19”). Two authors independently screened the articles and extracted the data. Qualitative analyses and a meta-analysis constituted 22 of the 794 retrieved articles. Differences in the hospitalization and mortality rates were used as the main measures of efficacy, and the meta-analysis was performed using RevMan software. Results 22 clinical trials were selected. The hospitalization rate was lower in the 3,216 patients who received DMTs than in the 774 patients who did not receive any treatment, with a moderate effect size of 0.43 (p<0.00001). The mortality rate was also lower among patients with MS treated using DMTs than in controls (odds ratio [OR]=0.19, 95% confidence interval [CI]=0.13–0.27, p<0.00001). The hospitalization rates for COVID-19 infection in patients with MS treated with anti-CD20 therapy also increased markedly (OR=3.32, 95% CI=2.63–4.20, p<0.00001). However, there was no significant difference between patients with MS who did and did not receive DMTs. Conclusions In summary, the application of DMTs was found to be valuable for patients with MS infected with COVID-19. However, more clinical studies are needed to determine the use of anti-CD20 drugs in patients with MS during the COVID-19 pandemic.

Do CEOs Who Are Raising Daughters Reduce Company Risk-taking?
Mingming Feng,Xia Wang,Xiaodong Xu,Mengjiao Zhou 한국증권학회 2024 Asia-Pacific Journal of Financial Studies Vol.53 No.1
Family structure and characteristics are important factors that affect both economic development and CEOs' decision‐making. Corporate risk‐taking reflects the overall risk choices and preferences of decision‐makers in relation to various decisions. Using data for Chinese non‐state‐owned enterprises between the years 2000 and 2019, we examine the association between CEO offspring gender and corporate risk‐taking. We find that CEOs who have daughters are associated with a lower level of corporate risk‐taking than CEOs who have sons only. Raising daughters significantly stimulates cautious attitudes and behaviors in CEOs and reduces firm overinvestment, thereby lowering the level of corporate risk‐taking. Moreover, raising daughters has a more significant inhibitory effect on corporate risk‐taking for female CEOs and CEOs who were born in regions with a strong patriarchal culture. Our findings also show that CEOs with daughters can help companies effectively avoid financial crises. Focusing on both parenting behavior and corporate financial behavior, we suggest that the parent–child relationship extends far beyond the scope of the family, providing a broader perspective for understanding corporate decision‐making and financial behavior.
