Previous studies have suggested that ticagrelor exerted chemotherapeutic effects by inhibition of epithelial-mesenchymal transition (EMT) in various diseases including tumors.

Electron ionization mass spectrometry feature peak relationships combined with deep classification model to assist similarity algorithm for fast and accurate identification of compounds.

Rationale: Gas chromatography-mass spectrometry (GC-MS) combines chromatography and MS, providing full play to the advantages of high separation efficiency of GC, strong qualitative ability of MS, and high sensitivity of detector. In GC-MS data processing, determining the experimental compounds is one of the most important analytical steps, which is usually realized by one-to-one similarity calculations between the experimental mass spectrum and the standard mass spectrum library. Although the accuracy of the algorithm has been improved in recent years, it is still difficult to distinguish structurally similar mass spectra, especially isomers.

Lateral Habenula Neurons Signal Cold Aversion and Participate in Cold Aversion.

The aversion to cold is a fundamental motivated behavior that contributes to the body temperature homeostasis. However, the involvement of the lateral habenula (LHb) as a regulatory hub for negative emotions in this physiological process remains uninvestigated. In this study, we demonstrate an elevation in the population activity of LHb neurons following exposure to cold stimuli.

The role of long non-coding RNAs in carbohydrate and fat metabolism in the liver.

The metabolism of carbohydrates and lipids (fat) in the liver is closely interconnected both in physiological conditions and in pathology. This relationship in the body is possible due to the regulation by many factors, including epigenetic ones. Histone modifications, DNA methylation, and non-coding RNAs are considered to be the main epigenetic factors.

The role of long non-coding RNAs in the development of adipose cells.

In recent times, the rising prevalence of obesity and its associated comorbidities have had a severe impact on human health and social progress. Therefore, scientists are delving deeper into the pathogenesis of obesity, exploring the role of non-coding RNAs. Long non-coding RNAs (lncRNAs), once regarded as mere "noise" during genome transcription, have now been confirmed through numerous studies to regulate gene expression and contribute to the occurrence and progression of several human diseases.

Regulation and mechanism of action of miRNAs on insulin resistance in skeletal muscles.

The term "insulin resistance" is commonly understood as a decrease in the response of insulin-sensitive tissues to insulin at its sufficient concentration, leading to chronic compensatory hyperinsulinemia. Type 2 diabetes mellitus is based on mechanisms consisting in the development of resistance to insulin in target cells (hepatocytes, adipocytes, skeletal muscle cells), resulting in the termination of an adequate response of these tissues to interaction with insulin. Since in healthy people 75-80% of glucose is utilized by skeletal muscle, it is more likely that the main cause of insulin resistance is impaired insulin-stimulated glucose utilization by skeletal muscle.

Exosomal non coding RNAs as a novel target for diabetes mellitus and its complications.

Diabetes mellitus (DM) is a first-line priority among the problems facing medical science and public health in almost all countries of the world. The main problem of DM is the high incidence of damage to the cardiovascular system, which in turn leads to diseases such as myocardial infarction, stroke, gangrene of the lower extremities, blindness and chronic renal failure. As a result, the study of the molecular genetic mechanisms of the pathogenesis of DM is of critical importance for the development of new diagnostic and therapeutic strategies.

The role of circular RNAs in the pathophysiology of oral squamous cell carcinoma.

Circular RNAs are non-coding RNAs that widely exist in eukaryotes. The research progress of its generation mechanism and biological function show that circular RNAs may be used in the development of tumors, neurological diseases, cardiovascular diseases. They play an important role in the occurrence and development of diseases and has a potential to be used as a disease marker.

The role of noncoding RNAs in the osteogenic differentiation of human periodontal ligament-derived cells.

Human periodontal ligament-derived cells are important seed cells for periodontal regeneration, and their osteogenic potential closely affects alveolar bone repair and periodontal regeneration. Human periodontal ligament stem cells are pluripotent stem cells of mesenchymal origin, which can differentiate in osteoblasts and cementoblasts. However, the molecular mechanism of this differentiation activity is poorly studied.

Circular RNAs as biomarkers for lung cancer.

Lung cancer is the leading cause of death and morbidity from malignant neoplasms worldwide, and its poor prognosis places a heavy burden on patients. A large percentage of lung cancer cases are associated with smoking. A significant number of non-smokers also develop the disease, suggesting an epigenetic and genetic mechanism for the development of lung cancer.

Clinical study on the treatment of primary trigeminal neuralgia by robot-assisted percutaneous balloon compression.

Background: C-arm-guided percutaneous puncture balloon compression alone has risk factors of puncture failure, complications, and poor prognosis. Robot-assisted PBC can effectively increase the one-time puncture success rate and improve the safety of the procedure. However, evidence on the superiority of robot-assisted PBC over C-arm-guided PBC alone remains relatively limited.

LncRNA as potential biomarker and therapeutic target in glioma.

Glioma is the most frequent type of malignant tumor in the central nervous system, accounting for about 80% of primary malignant brain tumors, usually with a poor prognosis. A number of studies have been conducted on the molecular abnormalities in glioma to further understand its pathogenesis, and it has been found that lncRNAs (long non-coding RNA) play a key role in angiogenesis, tumor growth, infiltration and metastasis of glioma. Since specific lncRNAs have an aberrant expression in brain tissue, cerebrospinal fluid as well as peripheral circulation of glioma patients, they are considered to be potential biomarkers.

The development of the vertebrate vascular system is an extremely important and complex process. The circulatory system is the first organ system to develop during embryogenesis. The development of the vasculature into highly branched canals must occur clearly in many places in order to supply oxygen and nutrients to the rapidly developing embryo.

The role of long non-coding RNA ANRIL in the development of atherosclerosis.

Atherosclerosis is an important pathological basis of coronary heart disease, and the antisense non-coding RNA in the INK4 locus (ANRIL) is located in the genetically susceptible segment with the strongest correlation with it - the short arm 2 region 1 of chromosome 9 (Chr9p21). ANRIL can produce linear, circular and other transcripts through different transcriptional splicing methods, which can regulate the proliferation and apoptosis of related cells and closely related to the development of atherosclerotic plaques. Linear ANRIL can regulate proliferation of vascular smooth muscle cells (VSMCs) in plaques by chromatin modification, as well as affecting on proliferation and the apoptosis of macrophages at the transcriptional level; circular ANRIL can affect on proliferation and apoptosis of VSMCs by chromatin modification as well as interfering with rRNA maturation.
