AIMS: Multiple exostoses (MO), also referred to as hereditary multiple exostoses (HME), is an autosomal dominant inherited skeletal disorder that has been found to be associated with mutations in the EXT1 and EXT2 genes. In the present study, we report a Chinese family with HME and undertake a mutational analysis of the EXT1 and EXT2 genes in affected and unaffected individuals. METHODS: All exons of the EXT1 and EXT2 genes in seven members of the family were polymerase chain reaction amplified from blood and sequenced...

OBJECTIVE: Asthma is the most common chronic pulmonary disease in China and is characterized by airway inflammation and episodic airflow obstruction. The aim of this meta-analysis was to evaluate the relation of the transforming growth factor-β1 (TGF-β1) polymorphisms with asthma risk in Chinese population. METHODS: PubMed, Springer, EMBASE, MEDLINE, CNKI (China National Knowledge Infrastructure), and Wanfang databases were used to search and retrieve relevant eligible case-control studies published through December 2017...

BACKGROUND: Interleukin 6 (IL-6), a proinflammatory cytokine, is elevated in patients with type 2 diabetes (T2D), and is considered an independent predictor of T2D. IL-6 single-nucleotide polymorphisms (SNPs) have been associated with higher levels of IL-6. This study investigated the role of an IL-6 gene polymorphism and its possible association to T2D in the genetically homogeneous Greek population of the island of Crete. MATERIALS AND METHODS: A total of 144 patients with T2D and 180 controls, all Cretans, selected from the Diabetes Clinic and the Department of Internal Medicine at the University Hospital of Heraklion, Crete, Greece, were genotyped for the IL-6 -174G>C (rs1800795) SNP by the restriction fragment length polymorphism method...

BACKGROUND: Retinitis pigmentosa (RP) is a rare type of inherited retinal dystrophy that can result in progressive vision loss. Molecular diagnosis of RP is challenging due to phenotypic and genotypic heterogeneities. AIMS: This study aimed to identify the pathogenic mutations in two Chinese families with autosomal dominant RP (adRP) and in a patient with sporadic RP. MATERIALS AND METHODS: Peripheral blood DNA samples were obtained from the participants...

AIMS: Nonsyndromic cleft lip with or without palate (NSCL/P) represents a complex condition caused by genetic and environmental factors. The aim of this study was to investigate the relationship between the EPHA3 polymorphisms and NSCL/P. MATERIALS AND METHODS: To investigate the relationship between five EPHA3 single nucleotide polymorphisms (SNPs) and NSCL/P, we selected 180 affected patients and 167 normal controls from the Chinese Han Population. EPHA3 SNPs (rs7650466, rs1398197, rs17801309, rs1054750, and rs7632427) were genotyped using the SNaPshot technique and used to perform bioinformatic analyses to determine if any of them were potentially functional SNPs...

BACKGROUND: Tumor-associated antigen overexpression, which has been reported in many types of cancers, may trigger autoantibody secretion. The present study was designed to test whether levels of circulating autoantibodies to survivin protein-derived antigens is altered in liver, esophageal, breast, and lung cancers. METHODS: Patients with liver (144), esophageal (159), breast (124), and lung cancers (267), and healthy volunteers (362) were recruited for the study, and serum samples were collected for ELISA autoantibody analysis...

BACKGROUND: Protein aggregate myopathies (PAM) represent a group of familial or sporadic neuromuscular conditions with marked clinical and genetic heterogeneity that occur in children and adults. Familial PAM includes myofibrillar myopathies defined by the presence of desmin-positive protein aggregates and degenerative intermyofibrillar network changes. PAM is often caused by dysfunctional genes, such as DES, PLEC 1, CRYAB, FLNC, MYOT, ZASP, BAG3, FHL1, and DNAJB6. OBJECTIVE: To retrospectively analyze genetic mutations and demographic, clinical, and morphological aspects of PAM in a French population...

AIMS: The homeobox (HOX) genes function as transcriptional factors that can promote tumorigenesis. However, the expression profile of HOXA10 and the role this protein plays in solid tumors are unclear. Here we examined HOXA10 protein expression in samples from colorectal cancer (CRC) patients to address the clinical significance of this protein. MATERIALS AND METHODS: Seven independent investigations from the Oncomine database were retrieved. A total of 85 patients who underwent radical excision followed by 5-fluorouracil (5-FU)-based adjuvant chemotherapy were enrolled...

AIMS: Essential tremor (ET) is one of the most common adult-onset movement disorders. ET and Parkinson's disease (PD) overlap clinically and pathologically, which prompted this investigation into the association of PD risk variants in ET patients. This study was designed to explore the role of variants of two PD-related genes LRRK1 and LRRK2 in a Han Chinese ET population. MATERIALS AND METHODS: Genetic analysis of LRRK1, rs2924835, and LRRK2, rs34594498, rs34410987, and rs33949390 variants was conducted on 200 Han Chinese patients with ET and 434 ethnically matched normal controls...

AIMS: Poly (ADP-ribose) polymerase-1 (PARP-1) plays an important role in the repair of damaged DNA and has prognostic significance in a variety of human malignancies. However, little is known about its expression levels and clinical implication in patients with acute myeloid leukemia (AML). MATERIALS AND METHODS: Quantitative reverse transcription-polymerase chain reaction was done to evaluate PARP-1 expression levels in the bone marrow of 65 patients with non-M3 AML and 54 healthy counterparts...

BACKGROUND: Noncoding RNAs (ncRNAs), primarily microRNAs and long ncRNAs, play important roles in lung cancer. However, the role of long ncRNA (lncRNA)-X-inactive specific transcript (XIST) in non-small-cell lung cancer (NSCLC) is unclear. The purpose of this study was to explore the biologic function and potential mechanism of XIST in NSCLC progression.

BACKGROUND: Interleukin-31 (IL-31), a novel T helper type 2 effector cytokine, is known to have an important effect on the pathogenesis of allergic disease and tumors. However, the impact of IL-31 on human lung cancer remains unclear. METHODS: This study explored the role of IL-31 polymorphisms in lung cancer and sought to characterize how IL-31 polymorphisms correlate with lung cancer tumorigenesis and patient survival rates. Using a single-nucleotide polymorphism genotype assay, we examined the expression of two IL-31 polymorphisms (rs7977932 and rs4758680) in samples from 302 lung cancer patients and 493 control cases...
