Prenatal diagnosis indicated that the present pregnancy of the patient's mother was not affected. Conclusion Our study expands the mutation spectrum of COL7A1 and demonstrated that CES and minigene assays were efficient tools for RDEB molecular diagnoses.Background Long non-coding RNAs (lncRNAs) have been identified as crucial regulatory factors in the occurrence and progression of osteosarcoma. Methods Quantitative real-time polymerase chain reaction was used for detecting small nucleolar RNA host gene 4 (SNHG4) and miR-377-3p in osteosarcoma cells and tissues. Kaplan-Meier method was applied for evaluating the association between SNHG4 expression and the overall survival of osteosarcoma patients. CCK8, EdU, flow cytometry, and transwell assay were performed to examine the cell proliferation, apoptosis, cycle, and migration of osteosarcoma cells. Results In our study, we found that lncRNA SNHG4 was highly expressed in osteosarcoma tissues and cell lines. Additionally, the SNHG4 expression was related to distant metastasis, TNM stage, and survival of osteosarcoma patients. Through SNHG4 knockdown, the proliferation of osteosarcoma cells was considerably restrained and the cell apoptosis was induced in vivo and in vitro. Moreover, downregulated SNHG4 inhibited the cell migration and epithelial-mesenchymal transition in HOS and MG63 cells. In mechanism, we found that SNHG4 acts as a competing endogenous RNA to sponge miR-377-3p, which is downregulated in osteosarcoma. Our results showed that there is a negative correlation between SNHG4 and miR-377-3p expression in osteosarcoma patients. Conclusion Taken together, SNHG4 promotes cell proliferation and migration by sponging miR-377-3p in osteosarcoma.Belonging to the chalcogen group, the elements selenium (Se) and tellurium (Te) are located in Group VI-A of the periodic table. Zero-valent nanodimensioned Se (nano-Se) and Te (nano-Te) have displayed important biomedical applications in recent years. The past two decades have witnessed an explosion in novel cancer treatment strategies using nano-Se and nano-Te as aggressive weapons against tumors. Indeed, they are both inorganic nanomedicines that suppress tumor cell proliferation, diffusion, and metastasis. Abundant synthesis strategies for rational and precise surface decoration of nano-Se and nano-Te make them significant players in resisting cancers by means of powerful multi-modal treatment methods. This review focuses on the design and engineering of nano-Se- and nano-Te-based nanodelivery systems and their precise uses in cancer treatment. The corresponding anticancer molecular mechanisms of nano-Se and nano-Te are discussed in detail. Given their different photo-induced behaviors, the presence or absence of near infrared illumination is used as a defining characteristic when describing the anticancer applications of nano-Se and nano-Te. Finally, the challenges and future prospects of nano-Se and nano-Te are summarized and highlighted.Invited for this month's cover is the group of Gyorgy Szekely at King Abdullah University of Science and Technology (KAUST).

Juvenile hormone (JH) is known to stimulate Vitellogenin (Vg) synthesis in the fat body, secretion into the hemolymph and uptake by developing oocytes. However, the role of GPCRs in JH-dependent insect vitellogenesis and oocyte maturation remains elusive. In the present study, we performed transcriptomic analysis and RNAi screening in vitellogenic females of the migratory locust Locusta migratoria. Of 22 GPCRs identified in ovarian transcriptome, LGR4, OR-A1, OR-A2, Mthl1, Mthl5 and Smo were most abundant in the ovary. By comparison, mAChR-C expressed at higher levels in the fat body, whereas Oct/TyrR, OARβ, AdoR and ADGRA3 were at higher expression levels in the brain. Our RNAi screening demonstrated that knockdown of 6 GPCRs resulted in defective phenotypes of Vg accumulation in developing oocytes, accompanied by blocked ovarian development and impaired oocyte maturation. While LGR4 and Oct/TyrR appeared to control Vg synthesis in the fat body, OR-A1, OR-A2, mAChR-C and CirlL regulated Vg transportation and uptake. learn more The findings provide fundamental evidences for deciphering the regulatory mechanisms of GPCRs in JH-stimulated insect reproduction.Objective Epidemiological evidence investigating serum uric acid and kidney cancer risk remains unclear. We conducted this study to examine the relationship between serum uric acid and the incidence and mortality of kidney cancer. Methods This is a prospective analysis of 444 462 participants without any cancer from the UK Biobank. Serum uric acid was measured at baseline and the incidence and mortality of kidney cancer was determined through contact with the cancer and death registry. Cox regression models were fitted to estimate the hazard ratio (HR) and 95% confidence interval (95%CI), adjusting for demography, lifestyle style, comorbidities, and medication use. Results We documented 638 incidence cases and 188 mortality cases of kidney cancer over a median of 6.5 years follow-up. People with the highest quartile had a 45% increased risk of kidney cancer compared to those with the lowest uric acid quartile (HR 1.45, 95%CI 1.08 to 1.93). Subgroup analyses showed that serum uric acid was associated with cancer risk among females but not among males (Q1 vs Q4 females HR1.47, 95%CI 1.01 to 2.16; males HR 1.19, 95%CI 0.91 to 1.56). Although we found serum uric acid was associated with an increased risk of kidney cancer mortality in age-stratified model (HR 2.49, 95% CI 1.61 to 3.84), this association disappeared after further adjustment for other confounders. Conclusions High uric acid is associated with a high incidence of kidney cancer, especially in women. More research is needed to confirm our findings.
