Pegoraro and colleagues present the clinical and molecular features of 21 patients with pediatric ECD through a large international collaboration, documenting that it resembles its adult counterpart, with similar molecular features and responses to agents targeting BRAF and MEK.

Therapeutic Effects of Shikonin on Skin Diseases: A Review.

Shikonin is one of the primary active components extracted from the dried root of (), a traditional Chinese herbal medicine. Shikonin is known to not only exert anti-proliferative, anti-inflammatory, and anti-angiogenic activities, but also play a crucial role in triggering the production of reactive oxygen species, suppressing the release of exosomes, and inducing apoptosis. Increasing evidence suggests that shikonin has a protective effect against skin diseases, including psoriasis, melanoma, and hypertrophic scars.

A comprehensive evaluation of skin aging-related circular RNA expression profiles.

Background: Circular RNAs (circRNAs) have been shown to play important regulatory roles in a range of both pathological and physiological contexts, but their functions in the context of skin aging remain to be clarified. In the present study, we therefore, profiled circRNA expression profiles in four pairs of aged and non-aged skin samples to identify identifying differentially expressed circRNAs that may offer clinical value as biomarkers of the skin aging process.

Methods: We utilized an RNA-seq to profile the levels of circRNAs in eyelid tissue samples, with qRT-PCR being used to confirm these RNA-seq results, and with bioinformatics approaches being used to predict downstream target miRNAs for differentially expressed circRNAs.

iTRAQ quantitative proteomic analysis differentially expressed proteins and signal pathways in henoch-schönlein purpura nephritis.

Henoch-Schönlein purpura nephritis (HSPN) has been considered as a major cause of chronic renal failure in children and a condition which can worsen clinical outcomes in adults. At present, the molecular mechanisms of HSPN are still unclear. In this study, iTRAQ quantitative proteomic analysis was performed on renal tissues collected from patients with HSPN and compared with those of patients after nephrectomy (controls).

Comparative study of treatment for striae alba stage striae gravidarum: 1565-nm non-ablative fractional laser versus fractional microneedle radiofrequency.

Striae gravidarum is a common dermatologic condition for females caused by multiple factors during pregnancy. It remains a therapeutic challenge especially in the striae alba (SA) stage, generating psychological and emotional distress to those affected. This study aims to compare the efficacy and safety of 1565-nm non-ablative fractional laser (NAFL) and fractional microneedle radiofrequency (MRF) for treatment of SA striae gravidarum.

Comprehensive upstream and downstream regulatory analyses identify miR-675-3p as a potential prognostic biomarker in melanoma.

This study assessed miR-675-3p-related regulatory mechanisms in melanoma and the clinical relevance of such regulatory activities. We downloaded miRNA mature strand expression RNA-Seq, phenotypic, and DNA methylation data pertaining to the TCGA Melanoma cohort. Differentially expressed miRNAs (DEMs) between metastatic and primary melanoma patient tissues were then identified, and miR-675-3p expression in melanoma patient peripheral blood was confirmed using the GSE20994 GEO dataset, while its expression in melanoma cell lines was evaluated via qRT-RCR.

The Current State of Research Regarding the Role of Non-Coding RNAs in Cutaneous Squamous Cell Carcinoma.

Skin cancers, including those of both both melanoma and non-melanoma subtypes, remain among the most common forms of human cancer. Non-melanoma skin cancers are typically further differentiated into the basal cell carcinoma and cutaneous squamous cell carcinoma (cSCC) categories. Current approaches to diagnosing and treating cSCC remain unsatisfactory, and the prognosis for patients with this disease is relatively poor.

Prevalence and influencing factors of nonunion in patients with tibial fracture: systematic review and meta-analysis.

Objective: The aim of this study is to assess the prevalence of nonunion in patients with tibia fracture and the association between influencing factors and tibia fracture nonunion.

Method: A database searches of PubMed, the Cochrane Library, EMBASE, China National Knowledge Infrastructure (CNKI), Weipu database, and Wanfang database from inception until June 2019 was conducted. The pooled prevalence, odds ratio (OR), and 95% confidence intervals (CI) were calculated with Stata software.

Cytoprotective effects of a proprietary red maple leaf extract and its major polyphenol, ginnalin A, against hydrogen peroxide and methylglyoxal induced oxidative stress in human keratinocytes.

Phytochemicals from functional foods are common ingredients in dietary supplements and cosmetic products for anti-skin aging effects due to their antioxidant activities. A proprietary red maple (Acer rubrum) leaf extract (Maplifa™) and its major phenolic compound, ginnalin A (GA), have been reported to show antioxidant, anti-melanogenesis, and anti-glycation effects but their protective effects against oxidative stress in human skin cells remain unknown. Herein, we investigated the cytoprotective effects of Maplifa™ and GA against hydrogen peroxide (H2O2) and methylglyoxal (MGO)-induced oxidative stress in human keratinocytes (HaCaT cells).

Stabilized diverse HIV-1 envelope trimers for vaccine design.

One of the major goals in HIV-1 vaccine development is to achieve properly folded and stabilized envelope glycoprotein (Env) trimers that mimic the native Env on the mature virion. Here, we design and characterize uncleaved prefusion-optimized (UFO) trimers for 12 Envs currently circulating in China. Biochemical and biophysical characterization of these UFO trimers identified two subtype B/B' Envs, CNE6 and MG13, which exhibited the highest trimer content and stability at a level comparable to the subtype A reference, BG505.

GSK-3β mediates ischemia-reperfusion injury by regulating autophagy in DCD liver allografts.

To elucidate the role of autophagy in ischemia-reperfusion injury (IRI) and determine whether glycogen synthase kinase-3β (GSK-3β) plays an important role in autophagy, a donors of cardiac death (DCD) liver transplantation model was established to observe the expression of GSK-3β and autophagy in hepatocytes during liver IRI. Immunohistochemical staining and western blotting were used to detect expression of the autophagy markers, LC3 and p62, as well as study the expression of GSK-3β and AMPK. Serum enzymology changes were analyzed at different times after liver transplantation.
