The CYP21A2 gene encoding 21‑hydroxylase is on chromosome 6p21.3 within the human leukocyte antigen (HLA) class III major histocompatibility complex and an association between congenital adrenal hyperplasia (CAH) due to 21‑hydroxylase deficiency and HLA class I and II alleles has been shown in genetically isolated populations. One-third of CAH causing alleles are 30-kb deletions due to homologous recombination events between active and pseudogenes resulting in chimeric genes. The aim of this study was to re-visit the association between the CYP21A2 variants and HLA polymorphisms in a large ethnically diverse cohort of patients with CAH who underwent comprehensive CYP21A2 genotyping, including specification of chimeric gene subtypes (CAH CH-1 through CH-9 of CYP21A1P/CYP21A2 chimeras; CAH-X CH-1 through CH-3 of TNXA/TNXB chimeras) in alleles with 30-kb deletions...

Pests have been subjected to heavy selection by insecticide pressure, producing greater and more serious resistance. It is extremely valuable to identify the resistance genes that are relevant for pest control. In our previous studies, we reported that UBL40 is the deltamethrin resistance-associated gene. UBL40 is cleaved by specific endopeptidases to release UB and L40. Therefore, further we compared the expression of UB and L40 in different tissues from larvae of the diamondback moth using a deltamethrin-resistant (DR) strain and a deltamethrin-sensitive (DS) strain...

Acute lung injury (ALI) is a serious clinical syndrome that can cause respiratory failure and threaten the life of the patients. A biomarker that can predict the syndrome can contribute to a better clinical management of the patients. In adults, genetic polymorphisms in inflammatory-response genes have been shown to be a promising biomarker. However, the pathogenesis of ALI in adult is known to be different from that in children and no previous study has investigated the association between inflammatory gene polymorphisms and pediatric ALI (PALI) risk...

Ferritin is not only a biomarker of total iron status and systemic inflammation but is also associated with metabolic disorders. A number of genetic variations have been identified to affect serum ferritin, but there is limited understanding of the genetic variations in serum ferritin. To evaluate the relationships among genetic variations, metabolism and ferritin, we performed a secondary analysis of our previous genome-wide association study of ferritin. After adjusting for population stratification and age, the rs671 in ALDH2 was significantly associated with ferritin concentrations (P-combined = 2...

MEG2 was recently found to have important functions in human cancers. However, the expression status and biological functions of MEG2 in hepatocellular carcinoma (HCC) remain unknown. In this study, we demonstrated that MEG2 expression was reduced in HCC tissues and cell lines using qRT-PCR, western blot and immunohistochemical staining. Decreased MEG2 expression predicted unfavorable clinical features and decreased overall survival and disease-free survival of HCC patients. In vitro functional assays showed that overexpression of MEG2 inhibited the cell viability, migration and invasion of HCCLM3 cells while MEG2 knockdown promoted these biological functions of Hep3B cells...
