Recent studies have reported an increasing incidence of ischemic stroke, particularly in younger age groups. Dental pulp stem cells (DPSCs) and periodontal ligament stem cells (PDLSCs) are the most common stem cells acquired from the teeth of adults, even elderly people. However, there are no detailed reports on whether DPSCs or PDLSCs are suitable for the treatment of ischemic stroke. In this study

RT-PCR and western blot analysis were carried out to examine the expressions of related RNAs. Colony formation

As a major type of immune cells with heterogeneity and plasticity, macrophages are classically divided into inflammatory (M1) and alternative/anti-inflammatory (M2) types and play a crucial role in the progress of the inflammatory diseases. Recent studies have shown that metabolism is an important determinant of macrophage phenotype. Mitochondria, one of the most important compartments involving cell

Homeobox c6 (Hoxc6) affects the proliferation, migration, and infiltration of malignant tumor cells; however, the effect of Hoxc6 on atherosclerosis (AS) as well as the proliferation and migration of vascular smooth muscle cells (VSMCs), which play a role in promoting AS, has not yet been well clarified. In the present study, we tested the hypothesis that Hoxc6 affects the proliferation and migration

Gastric cancer (GC) is one of the most common and lethal malignancies worldwide, and its poor prognosis is mainly due to the rapid tumor progression including tumor invasion, distant metastasis, etc. Understanding the molecular mechanisms regulating GC progression lays the basis for the development of targeted therapeutic agents.

The study of the interaction between Eimeria and host cells is the theoretical basis for the prevention and treatment of coccidiosis [2]. However, the specific mechanism of E. acervulina invasion is not very clear, so the interaction between the invading protein and the host awaits

MicroRNAs (miRNAs) are a class of endogenous small RNAs that regulate target gene expression at the post-transcriptional level. miRNAs play an important role in almost all physiological activities including the processes of embryonic stem cell (ESC) pluripotency maintenance and differentiation, as well as induced pluripotent stem cell (iPSC) reprogramming. In this study, we identified eight novel miRNAs

Platinum-based drugs such as cisplatin are widely used in combination chemotherapy for non-small cell lung cancer (NSCLC) owing to their high clinical response rate; however, acquired resistance to cisplatin is eventually inevitable. Circular RNAs (circRNAs) are involved in the development of diverse types of cancers, but their connection to cisplatin-resistance in NSCLC has not been studied. In the

Vasculogenic mimicry (VM) refers to a new tubular network of the blood supply system with abundant extracellular matrix. VM is similar to capillaries but does not involve endothelial cells.

Atherosclerosis is the pathological basis of most cardiovascular diseases, the leading cause of morbidity and mortality worldwide. Kallistatin, originally discovered in human serum, is a tissue-kallikrein-binding protein and a unique serine proteinase inhibitor. Upon binding to its receptor integrin β3, lipoprotein receptor-related protein 6, nucleolin, or Krüppel-like factor 4, kallistatin can modulate

Type 2 diabetes (T2D) is usually accompanied with a number of complications including neuropathologic changes. Not only peripheral neuropathies are frequently accompanied with diabetes, but also the structural and functional integrity of brain could be impaired in diabetic patients [1]. The risk of Parkinson’s disease (PD) is seven folds higher in diabetic patients than in normal people [2]. Clinical

Myocardial hypertrophy is a major pathological and physiological process during heart failure. Glucagon-like peptide 1 (GLP-1) is a glucagon incretin hormone released from the gut endocrine L-cells that has protective effects on various cardiovascular diseases, including hypertension, atherosclerosis, and myocardial hypertrophy.

Knockdown of miR-155 in the CD4+ T cells was achieved by lentiviral transfection, whereas control

Endoplasmic reticulum (ER)-associated degradation (ERAD) plays an essential role in protein quality control in the ER. It acts through recognizing misfolded or unassembled proteins and retrotranslocating them across the ER membrane into the cytosol for degradation. ER-phagy, which is an ERAD pathway, also controls the quality and abundance of proteins and organelles by activating ER-resident receptors

Lung cancer is the most prevalent cancer and the leading cause of cancer-related deaths worldwide. More than 80% of lung cancer incidences are non-small cell lung cancer (NSCLC), including adenocarcinoma, squamous carcinoma and large-cell lung cancer [1,2]. Although surgical resection is widely applied for patients with all types of NSCLC, different strategies such as radiotherapy and multimodal neoadjuvant

Bimolecular fluorescence complementation (BiFC) is a popular method used to detect protein–protein interactions. For a BiFC assay, a fluorescent protein is usually split into two parts, and the fluorescence is recovered upon the interaction between the fused proteins of interest. As an elegant extension of BiFC, a tripartite superfold green fluorescent protein (sfGFP) system that has the advantages

Bone mineral density (BMD) is used to assess bone mass at present and ~70% of the variance is determined by genetic factors [1]. BMD in a lifetime is in a dynamic change from peak values obtained during growth to a gradual decrease during postmenopause and aging. Bone micro-architecture deterioration in postmenopausal women is a result of increased bone remodeling and liable to fracture of the hip

Neuron-restrictive silencer factor (NRSF) is a zinc finger protein that acts as a negative transcriptional regulator by recruiting histone deacetylases and other co-factors.
