Inhibitory effects of circR-127aa on gastric cancer progression and tumor growth.

This study investigates the function of a newly identified 127-amino acid peptide, circR-127aa, encoded by hsa_circ_0075402 (circRACK1), in gastric cancer (GC), a condition with significant prevalence in China. Utilizing a comprehensive analysis of circular RNA (circRNA) ribosome profiling data alongside experimental validations through mass spectrometry, Western blot, and immunofluorescence, we demonstrate that circR-127aa Inhibits Malignant Phenotypes and suppresses tumor growth in nude mice models. Significantly, the interaction of circR-127aa with Vimentin, a crucial element in actin-actin-cytoskeletal remodeling, indicates that circR-127aa functions as a tumor suppressor by facilitating the ubiquitination of Vimentin.

Immunotherapy in operable non-small cell lung cancer: a systematic review and network meta-analysis of efficacy between neoadjuvant immunochemotherapy and perioperative immunotherapy.

Background: A series of randomized controlled trials (RCTs) have demonstrated the promising prospect of immunotherapy in operable non-small cell lung cancer (NSCLC) and further changed the clinical practice. However, current studies still yet to answer which immunotherapy mode is the optimal strategy, and there is currently a lack of direct comparison between neoadjuvant immunochemotherapy and perioperative immunotherapy ("sandwich mode", including neoadjuvant immunochemotherapy and adjuvant immunotherapy). Thus, we conducted a network meta-analysis (NMA) to evaluate the efficacy between neoadjuvant immunochemotherapy and perioperative immunotherapy.

A ground reaction force model of speed skating based on non-contact measurement system.

Accurate collection and analysis of ground reaction force (GRF) data are crucial for optimizing the technical movements of speed skaters; however, it has been a challenge for the limitations of experimental equipment and application scenarios. Therefore, we proposed a novel approach for estimating GRF based on kinematics obtained from markerless video tracking systems and achieved low errors compared with the experimental data. Our method allows for further biomechanical analysis, including muscle force and power, during speed skating competitions.

The microprotein encoded by exosomal lncAKR1C2 promotes gastric cancer lymph node metastasis by regulating fatty acid metabolism.

Lymph node metastasis (LNM) is the prominent route of gastric cancer dissemination, and usually leads to tumor progression and a dismal prognosis of gastric cancer. Although exosomal lncRNAs have been reported to be involved in tumor development, whether secreted lncRNAs can encode peptides in recipient cells remains unknown. Here, we identified an exosomal lncRNA (lncAKR1C2) that was clinically correlated with lymph node metastasis in gastric cancer in a VEGFC-independent manner.

is involved in the fruit coloration in Mill. by regulating anthocyanin accumulation.

Fruit color is one of the most important traits of jujube ( Mill.). However, the differences in the pigments of different varieties of Jujube are not well studied.

Adipocyte-Derived Exosomal MTTP Suppresses Ferroptosis and Promotes Chemoresistance in Colorectal Cancer.

Obesity is closely related to a poor prognosis in patients with advanced colorectal cancer (CRC), but the mechanisms remain unclear. Ferroptosis is a form of nonapoptotic cell death characterized by lipid reactive oxygen species (ROS) accumulation and iron dependency and is associated with the chemoresistance of tumors. Here, it is shown that adipose-derived exosomes reduce ferroptosis susceptibility in CRC, thus promoting chemoresistance to oxaliplatin.

Quercetin and Allicin Can Alleviate the Hepatotoxicity of Lead (Pb) through the PI3K Signaling Pathway.

Lead (Pb) is a common toxic heavy metal pollutant in the environment that seriously endangers the health of animals. The liver is a key target organ affected by Pb toxicity. Plant extracts allicin and quercetin have a strong antioxidant capacity that can promote the excretion of heavy metals by improving the body's antioxidant defense and chelating heavy metal ions.

Long non-coding RNA MALAT1 interaction with miR-429 regulates the proliferation and EMT of lung adenocarcinoma cells through RhoA.

In this paper, we found that LncRNA MALAT1 had high expression in human LAC tissues (vs. paracancerous normal tissue) and human lung adenocarcinoma cells (vs.

Maximum allele frequency observed in plasma: A potential indicator of liquid biopsy sensitivity.

Personalized medicine is revolutionizing the diagnosis and treatment of cancer; however, for personalized medicine to be used accurately, patient information is essential to determine the appropriate diagnosis, prognosis and treatment. The detection of genomic mutations in liquid biopsy samples is a non-invasive method of characterizing the genotype of a tumor. However, next generation sequencing-based plasma genotyping only has a sensitivity of ~70%.

The ideal methods for the management of rib fractures.

The clinical treatment choices for multiple rib fractures and flail chest are controversial. For example, among conservative treatment and surgical treatment, different studies have different conclusions and recommendations. Furthermore, early clinical research was mainly focused on the treatment of flail chest due to its severity.
