Cell proliferation; Clone formation; Hypoxia; Periodontal ligament stem cells

There is high incidence of periodontal disease in high-altitude environments; hypoxia may influence the proliferation and clone-forming ability of periodontal ligament stem cells (PDLSCs). The MAPK signaling pathway is closely correlated with cell proliferation, differentiation, and apoptosis. Thus, we isolated and cultured PDLSCs under hypoxic conditions to ... more

Diagnosis; Meta-analysis; MicroRNAs; Thyroid cancer

The aim of this meta-analysis was to systematically evaluate the diagnostic accuracy of microRNAs (miRNAs) in distinguishing malignant thyroid lesions from benign ones and to determine the potential of miRNAs as diagnostic biomarkers for thyroid cancer. The random-effect model was used to summarize the pooled estimates of diagnostic accuracy, including sensitivity, specificity, positive ... more

Head and neck cancer; Meta-analysis; MicroRNAs; Screening

Head and neck cancer (HNC) is one of the most prevalent cancers; it is often diagnosed at its advanced stage and has a low 5-year survival rate. Evidence suggests that noninvasive biomarker microRNAs (miRNAs) are valuable for early diagnosis of HNC. This meta-analysis assessed the diagnostic value of miRNAs in HNC detection. A systematic literature search for relevant studies up to August ... more

Acute lymphoblastic leukemia; MicroRNAs; Microvesicles; Zinc finger protein genes

Microvesicles (MVs) are submicrometric membrane fragments that can “engulf” cytoplasmic contents such as microRNAs (miRNAs) from their cellular origin. The study of miRNAs carried within MVs might provide insights into the roles that miRNAs play in the underlying pathophysiologic processes of acute lymphoblastic leu­kemia (ALL). We identified numerous dysregulated MV miRNAs in patients ... more

Differentially expressed genes; MicroRNAs; RNA sequencing; Thyroid carcinoma; Transcription factors

In this study, we examined the molecular mechanism of thyroid carcinoma (THCA) using bioinformatics. RNA-sequencing data of THCA (N = 498) and normal thyroid tissue (N = 59) were downloaded from The Cancer Genome Atlas. Next, gene expression levels were calculated using the TCC package and differentially expressed genes (DEGs) were identified using the edgeR package. A co-expression ... more

Glioblastoma; ionizing radiation; MicroRNAs; miR-21; Neurospheres; Temozolomide

Glioblastomas are the most common primary malignant brain tumors, and despite current advances in therapy, they are still extremely resistant to treatment. The tumorigenic potential of glioblastomas is due to a subpopulation of neoplastic cells, called cancer stem cells (CSCs), which in culture form a suspension cluster called neurospheres. Their properties include ... more

meningiomas; MicroRNAs; Serum

Meningiomas are the most common primary tumors of the central nervous system, accounting for 35.5% of cases, considering all age groups. Despite progress made in recent decades, tumorigenesis of meningiomas still remains a challenge. There is a consensus of a need for molecular tools to assist in diagnosis and prognosis of meningiomas. In this context, some studies ... more

Reports of terminal and interstitial deletions of the long arm of chromosome 2 are rare in the literature. Here, we present a case report concerning a Chinese boy with a 47,XYY karyotype and a de novo deletion comprising approximately 5 Mb between 2q35 and q36.1, along with syndactyly, type III Waardenburg syndrome, and congenital heart disease. High-resolution chromosome analysis to detect ... more

The most common type of endocrine disease is type 2 diabetes mellitus (T2DM); genetic factors contribute to the development to T2DM. In this study, we investigated the role of the Leu53Leu, Arg213Gly, and Ala40Thr polymorphisms in extracellular superoxide dismutase (EC-SOD) gene in the development of T2DM in a Chinese population. DNA was extracted from peripheral blood samples obtained from ... more

The incidence of non-Hodgkin lymphoma (NHL) in China is increasing and is attracting attention as a topic of research. The percentage of NHL cases in ethnic Uighur people is also gradually increasing. We therefore recruited Uighur people with NHL to investigate the correlation between genetic alternations and clinical/pathological features in an attempt to determine their clinical significance ... more
