BACKGROUND: Gastric cancer (GC) is a prevalent malignant cancer of digestive system. To identify key genes in GC, mRNA microarray GSE27342, GSE29272, and GSE33335 were downloaded from GEO database. METHODS: Differentially expressed genes (DEGs) were obtained using GEO2R. DAVID database was used to analyze function and pathways enrichment of DEGs. Protein-protein interaction (PPI) network was established by STRING and visualized by Cytoscape software. Then, the influence of hub genes on overall survival (OS) was performed by the Kaplan-Meier plotter online tool...

Collagen cross-linking, as a form of collagen post-translational modification, plays a crucial role in maintaining bone mechanical properties as well as in regulating cell biological functions. Shifts in cross-links profile are found apparently correlated to kinds of skeletal pathology and diseases, whereas little is known about the relationship between collagen cross-links and osteogenesis. Here, we hypothesized that the inhibition of collagen cross-links could impair skeletal microstructure and inhibit osteogenesis...

We identified novel compound heterozygous mutations in SERPINH1 in a Chinese boy suffering from recurrent fractures, femoral deformities, and growth retardation, which resulted in extremely rare autosomal recessive OI type X. Long-term treatment of BPs was effective in increasing BMD Z-score, reducing fracture incidence and reshaping vertebrae compression. INTRODUCTION: Osteogenesis imperfecta (OI) is a heritable bone disorder characterized by low bone mineral density, recurrent fractures, and progressive bone deformities...

Osteogenesis imperfecta (OI) is an inherited disorder with osteoporosis and recurrent fractures. Children presenting with recurrent fractures and bowing of limbs have severe form of the disorder. Patients carrying homozygous WNT1 mutations have more frequent fractures while heterozygous carriers of the mutation in WNT1 gene are also found to have early onset osteoporosis. We identified a family with novel WNT1 mutation. The index case, a 6 month old child presented with fractures from early infancy. Next generation sequencing (NGS)done for the child didn't show any variations in other OI genes including COL1A1, COL1A2, SERPINH1, CRTAP, LEPRE1, PP1B, 1F1TM5 and BMP1 genes...

In recent years, plant-derived extracts are increasing interest from researchers worldwide due to good efficacy and lower side effects. Among the different plant extracts, Dracorhodin perchlorate (DP) is originated from Dragon's blood which has long been used as a natural medicine with various pharmacological activities. In the present study, we have explored the potential regulation of DP on fibroblast proliferation which promotes wound healing both in vitro and in vivo. DP at treatment of 12-24 h significantly induced fibroblast proliferation which is associated with increasing level of phosphorylated-extracellular signal-regulated kinase (ERK)...

Precision therapy for clear cell renal cell carcinoma (ccRCC) requires molecular biomarkers ascertaining disease prognosis. In this study, we performed integrated proteomic and transcriptomic screening in all four tumour-node-metastasis stages of ccRCC and adjacent normal tissues (n = 18) to investigate differentially expressed genes. Most identified differentially expressed genes revealed a strong association with transforming growth factor-β level and the epithelial-to-mesenchymal transition process. Of them, Serpin peptidase inhibitor clade H member 1 (SERPINH1) revealed the strongest association with poor prognosis and regulation on the expression levels of epithelial-to-mesenchymal transition markers...

Osteogenesis imperfecta (OI) is a genetic disease that occurs in humans and animals. Individuals with OI exhibit signs of extreme bone fragility and osteopenia with frequent fractures and perinatal lethality in severe cases. In this study, we report the clinical diagnosis of OI in a dog and the use of targeted next-generation sequencing to identify a candidate autosomal dominant mutation in the COL1A2 gene. A 5-month-old male Chow Chow was examined with a fractured left humerus and resolving, bilateral femoral fractures...

HSP47/SERPINH1 is key-regulator for collagen biosynthesis and its structural assembly. To date, there is no comprehensive study on the phylogenetic history of HSP47. Herein we illustrate the evolutionary history of HSP47/SERPINH1 along with sequence, structural and syntenic traits for HSP47/SERPINH1. We have identified ancestral HSP47/SERPINH1 locus in Japanese lamprey (Lethenteron japonicum). This gene remains on the same or similar locus for ~500 million years (MY), but chromosomal duplication was observed in ray-finned fishes, leading into three sets of three sets (I-III) of HSP47/SERPINH1...

Collagen is the most abundant protein in the extracellular matrix in humans and is critical to the integrity and function of many musculoskeletal tissues. A molecular ensemble comprising more than 20 molecules is involved in collagen biosynthesis in the rough endoplasmic reticulum. Two proteins, heat shock protein 47 (Hsp47/ SERPINH1 ) and 65-kDa FK506-binding protein (FKBP65/ FKBP10 ), have been shown to play important roles in this ensemble. In humans, autosomal recessive mutations in both genes cause similar osteogenesis imperfecta phenotypes...

Oviparous reptile embryos are expected to breach their critical thermal maxima if temperatures reach those predicted under current climate change models due to the lack of the maternal buffering processes and parental care. Heat-shock proteins (HSPs) are integral in the molecular response to thermal stress, and their expression is heritable, but the roles of other candidate families such as the heat-shock factors (HSFs) have not been determined in reptiles. Here, we subject embryonic sea turtles (Caretta caretta) to a biologically realistic thermal stress and employ de novo transcriptomic profiling of brain tissue to investigate the underlying molecular response...

Osteogenesis imperfecta (OI) is a heterogeneous disorder that causes fragility, deformity, and fractures in bones. A large number of genes that are associated with the disease have been identified in the last decade; this makes the genetic diagnosis of OI more difficult. To improve our knowledge of the genetic mutation profile in OI we used single-stranded conformation polymorphism screening and automated sequencing to investigate the SERPINH1, FKBP10, and SERPINF1 genes, which are related to recessive OI, in 23 unrelated Brazilian patients...

Grade IV glioblastoma multiforme (GBM) is the most malignant form of gliomas. HSP47, encoded by SERPINH1 gene, is a serpin which serves as a human chaperone protein for collagen. We have shown that HSP47 is significantly overexpressed in GBM and associated with tumor grade. However, the role of HSP47 on GBM progression and stemlike property remains unclear. The stable overexpression of HSP47 in primary GBM cells was established by lentivirus infection. The effects of HSP47 overexpression on tumor growth and the effects of blocking the TGF-β pathway on tumor regression were investigated by animal study...

Osteogenesis imperfecta (OI) is a genetic disorder characterised by low bone mineral density resulting in fractures. 85-90% of patients with OI carry a variant in the type 1 collagen genes, COL1A1 and COL1A2, which follows an autosomal dominant pattern of inheritance. However, within the last two decades, there have been growing number of variants identified in genes that follow an autosomal recessive pattern of inheritance. Our proband is a child born in Mexico with multiple fractures of ribs, minimal calvarial mineralisation, platyspondyly, marked compression and deformed long bones...

Brain gene expression profiling studies of suicide and depression using oligonucleotide microarrays have often failed to distinguish these two phenotypes. Moreover, next generation sequencing approaches are more accurate in quantifying gene expression and can detect alternative splicing. Using RNA-seq, we examined whole-exome gene and exon expression in non-psychiatric controls (CON, N=29), DSM-IV major depressive disorder suicides (MDD-S, N=21) and MDD non-suicides (MDD, N=9) in the dorsal lateral prefrontal cortex (Brodmann Area 9) of sudden death medication-free individuals post mortem...

Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive lung disease that is refractory to treatment and carries a high mortality rate. IPF is frequently associated with lung cancer. Identification of molecular targets involved in both diseases may elucidate novel molecular mechanisms contributing to their pathology. Recent studies of microRNA (miRNA) expression signatures showed that microRNA-29a (miR-29a) was downregulated in IPF and lung cancer. The aim of this study was to investigate the functional significance of miR-29a in lung cancer cells (A549 and EBC-1) and lung fibroblasts (MRC-5) and to identify molecular targets modulated by miR-29a in these cells...

Solar ultraviolet radiation (UVR) is the major risk factor for skin carcinogenesis. To gain new insights into the molecular pathways mediating UVR effects in the skin, we performed comprehensive transcriptomic analyses to identify shared and distinctive molecular responses to UVR between human keratinocytes and melanocytes. Keratinocytes and melanocytes were irradiated with varying doses of UVB (10, 20 and 30 mJ/cm(2) ) then analysed by RNA-Seq at different time points post-UVB radiation (4, 24 and 72 h). Under basal conditions, keratinocytes and melanocytes expressed similar number of genes, although they each expressed a distinctive subset of genes pertaining to their specific cellular identity...

Hepatocellular carcinoma (HCC) is one of the most aggressive tumors, and the treatment outcome of this disease is improved when the cancer is diagnosed at an early stage. This requires biomarkers allowing an accurate and early tumor diagnosis. To identify potential markers for such applications, we analyzed a patient cohort consisting of 50 patients (50 HCC and 50 adjacent nontumorous tissue samples as controls) using two independent proteomics approaches. We performed label-free discovery analysis on 19 HCC and corresponding tissue samples...
