Clear cell renal cell carcinoma (ccRCC) is the most common kidney malignancy, with a poor prognosis for advanced-stage patients. Identifying key biomarkers involved in tumor progression is crucial for improving treatment outcomes. In this study, we employed an integrated approach combining single-cell RNA sequencing (scRNA-seq) and bulk RNA sequencing (bulk RNA-seq) to identify biomarkers associated with ccRCC progression and prognosis.

Herein, we report that breaking continuous TiO tetragonal () symmetry in titanium dioxide material by oxygen vacancy engineering could induce a dipole field within the bulk phase and thus facilitate the separation and transfer of photogenerated electron-hole pairs. After further loading of Cu single-atom co-catalysts, the obtained catalyst attained a hydrogen (H) yield rate of 15.

Additionally, researching these innovative delivery carrier materials represents both a prominent focus and a significant challenge in the current scientific landscape. Here we designed new chiral self-assembling peptides as the delivery carrier for RNA vaccines to study the underlying mechanisms in the feline infectious peritonitis virus (FIPV) model system.

This study endeavored to delineate the atmospheric PM pollution in Beijing from 2015 to 2022 and to undertake comprehensive evaluation of carcinogenic risks associated with the composition of atmospheric PM during the year exhibiting the lowest concentration. PM concentrations were monitored gradually in 9 districts of Beijing for 7 consecutive days per month from 2015 to 2022, and 32 kinds of PM components collected in the lowest PM concentration year were analyzed.

Target to develop a new three-dimensional (3D) inflammatory model to airway system, and here we report a strategy by using self-assembling D-form peptide to cover the process. By testing physicochemical properties and biocompatibility of Sciobio-Ⅲ, we confirmed that it can rapidly self-assembles under the trigger of ions to form a 3D nanonetwork-like scaffold, which supports 3D cell culture including the cell strains like BEAS-2B cells.

The utilization of nanomaterials in the biosensor field has garnered substantial attention in recent years. Initially, the emphasis was on enhancing the sensor current rather than material interactions. However, carbon nanotubes (CNTs) have gained prominence in glucose sensors due to their high aspect ratio, remarkable chemical stability, and notable optical and electronic attributes.

Reduced graphene oxide (r-GO) with superior conductivity and electrochemical stability has been extensively investigated as an efficient capacitive electrode material. In this study, three-dimensional carbon dots (CDs)@r-GO hydrogel electrode was successfully in situ prepared by the one-pot method, where the CDs play a critical role in serving as both reduction agent and electrochemical active sites.

Background: Metallothioneins (MTs) involves in the tumorigenesis and prognosis of various cancers. The biological function and methylation status of MT1E in hepatocellular carcinoma (HCC) remain to be elucidated.
Methods: We analyzed differentially expressed genes (DEGs) in tumor tissue samples and normal samples from The Cancer Genome Atlas (TCGA) and Genotype-Tissue Expression (GTEx) database, and identified the expression levels of MT1E in the HCC.

Previous studies have reported associations of short-term exposure to different sources of ambient fine particulate matter (PM) and increased mortality or hospitalizations for respiratory diseases. Few studies, however, have focused on the short-term effects of source-specific PM on emergency room visits (ERVs) of respiratory diseases. Source apportionment for PM was performed with Positive Matrix Factorization (PMF) and generalized additive model was applied to estimate associations between source-specific PM and respiratory disease ERVs.

However, studies which explored the burden of ozone pollution on chronic obstructive pulmonary disease (COPD) and estimated the relevant economic loss were rare.
Objective: We explored the relationships between ambient ozone exposure and years of life lost (YLL) from COPD mortality and estimated the relevant economic loss in Ningbo, in the Yangtze River Delta of China, 2011-2015.
Objective: Air pollution is considered one of the most important risk factors for ischemic heart disease (IHD), which is a major public health concern. The disease burden of IHD has continued to rise in China in the past two decades. However, epidemiological studies examining the associations between air pollution and IHD have been scarce in China, and the only studies were conducted in severe air pollution areas, where air pollution levels seriously exceed the World Health Organization Air Quality Guidelines.

ATP6V0C was directly found to interact with LASS2/TMSG1 which is a new tumor metastasis inhibitory gene identified by our laboratory in 1999. In order to study the role of ATP6V0C, we generated small interference RNA (siRNA) targeting ATP6V0C and investigated its function on the invasion of human prostate cancer cell line PC-3M-1E8 with high metastatic potential and its interplay with LASS2/TMSG1.
