Time-resolved single-cell transcriptomic sequencing.

Cells experience continuous transformation under both physiological and pathological circumstances. Single-cell RNA sequencing (scRNA-seq) is competent in disclosing the disparities of cells; nevertheless, it poses challenges in linking the individual cell state at distinct time points. Although computational approaches based on scRNA-seq data have been put forward for trajectory analysis, the result is based on assumptions and fails to reflect the actual states.

mA modification of CDC5L promotes lung adenocarcinoma progression through transcriptionally regulating WNT7B expression.

Cell division cycle 5-like (CDC5L) protein is implicated in the development of various cancers. However, its role in the progression of lung adenocarcinoma (LUAD) remains uncertain. Our findings revealed frequent upregulation of CDC5L in LUAD, which correlated with poorer overall survival rates and advanced clinical stages.

Metal-free visible-induced C(sp)-C(sp) coupling of quinoxalin-2()-ones oxidative cleavage of the C-N bond.

A C(sp)-C(sp) reaction between aromatic hydrazines and quinoxalines has been developed through a photocatalytic system. The protocol is established for C(sp)-N bond cleavage and direct C(sp)-H functionalization for the coupling of C(sp)-C(sp) photocatalysis under mild and ideal air conditions without the presence of a strong base and metal. The mechanistic studies reveal that the generation of a benzene radical the oxidative cleavage of aromatic hydrazines for the cross-coupling of C(sp)-C(sp) with the assistance of a photocatalyst is essential.

DIPEA-induced activation of OH for the synthesis of amides photocatalysis.

The development of green protocols for photocatalysis where water acts as a nucleophile, induced by a weak organic base, is difficult to achieve in organic chemistry. Herein, an efficient light-mediated strategy for the synthesis of amides in which a weak organic base acts as a reductant to induce the formation of OH- from water under metal-free conditions is reported. A mechanistic study reveals that the generation of an ,-diisopropylethylamine (DIPEA) radical single electron transfer (SET), with the assistance of photocatalyst, that increases the nucleophilicity of the water molecules with respect to the cyanides is essential.

RPL35 promotes neuroblastoma progression via the enhanced aerobic glycolysis.

Neuroblastoma (NB) is an rare type of tumor that almost affects children age 5 or younger due to its rapid proliferation ability. The overall survival rate of patients with advanced NB is not satisfactory. Ribosomal proteins (RPs) play a critical role in the development and progress of cancer.

Multimerized self-assembled caged siRNA nanoparticles for photomodulation of RNAi-induced gene silencing.

We rationally designed and developed caged siRNA nanoparticles (Multi-Chol-siRNA) self-assembled with cholesterol-modified multimerized caged siRNAs for photomodulation of siRNA gene silencing activity. Strong resistance to serum nuclease and RNase A was observed for these cholesterol-modified caged siRNA nanoparticles due to the formation of nanostructures with high intensity of siRNA. These caged Multi-Chol-siRNA self-assembled nanoparticles were successfully used to achieve photochemical regulation of both exogenous GFP and endogenous Eg5 gene expressions with a GFP/RFP transient transfection system and Eg5-associated assays, respectively.

Potential mechanism of action of extract injection against cardiovascular diseases revealed by combination of HPLC-Q-TOF-MS, virtual screening and systems pharmacology approach.

extract injection, a Chinese medicine preparation named as Kudiezi injection (KDZI) in China, has been widely used for the treatment of cardiovascular diseases (CVDs) in recent years. Owing to the component complexity of the preparation, the study on the effect mechanism of the herbal medicine against CVDs is a big challenge. In this research, HPLC-Q-TOF-MS was used to analyze the constituents of the preparation, disclosing that the KDZI mainly consists of 10 ingredients, namely 3-caffeoylquinic acid (KDZI-1), 4-caffeoylquinic acid (KDZI-2), 5-caffeoylquinic acid (KDZI-3), apigenin-7--β-d-glucuronide (KDZI-4), caffeic acid (KDZI-5), chicoric acid (KDZI-6), caftaric acid (KDZI-7), luteolin-7--β-d-gentiobioside (KDZI-8), luteolin-7--β-d-glucopyranoside (KDZI-9) and luteolin-7--β-d-glucuronide (KDZI-10).

A simple fluorescence assay for trypsin through a protamine-induced carbon quantum dot-quenching aggregation platform.

The development of a simple detection strategy for trypsin (Try) is urgent, and is ascribed to the diagnostic value of Try in several diseases. Herein, a facile but effective fluorescence strategy for Try was developed based on the protamine (Pro)-induced aggregation of carbon quantum dots (CQDs). The fluorescence of negatively charged CQDs was quenched with Pro due to the assembly of CQDs and Pro (CQDs/Pro) through electrostatic interaction.

T cell recruitment triggered by optimal dose platinum compounds contributes to the therapeutic efficacy of sequential PD-1 blockade in a mouse model of colon cancer.

Recently, the combination of platinum chemotherapy with PD-1/PD-L1 pathway blockades has shown synergistic efficacy in a few clinical trials.

Fluorescence sensing of tyrosinase activity based on amine rich carbon dots through direct interaction in a homogeneous system: detection mechanism and application.

As a vital, copper-containing oxidase, tyrosinase (TYR) is useful as a biomarker for the screening of skin diseases. In this paper, a convenient and sensitive homogeneous fluorescence detection platform for the assay of TYR activity without any modified steps is described. Inspired by the fact that carbon dots (CDs) with excellent properties can be obtained through some surface modification, amine rich carbon dots (N-CDs) using a nitrogen doping process were developed as the fluorescent probe for this assay.

Insight into the DNA adsorption on nitrogen-doped positive carbon dots.

Considerable biosensors have been fabricated on the basis of DNA interaction with carbon nanomaterials, such as graphene oxide (GO) nanosheets. Few studies have focused on the rational design of sensors between carbon dots (CDs) and DNA due to the limited understanding of the real forces behind the adsorption of DNA on CDs. In this work, nitrogen doping-positive CDs (N-CDs), which can quench fluorophore-labeled DNA, were investigated to ascertain the interaction between the CDs and DNA.

A fluorescent sensor constructed from nitrogen-doped carbon nanodots (N-CDs) for pH detection in synovial fluid and urea determination.

The N-CDs showed stable and strong emission bands at approximately 455 nm under 350 nm excitation. Moreover, the fluorescence of N-CDs can be gradually decreased by gradually increasing the pH value.
