Laryngeal squamous cell carcinoma (LSCC) is a common malignant tumor of the otolaryngeal region and accounts for 1–2% of all malignancies diagnosed worldwide. miR-340 down-regulation and EZH2 up-regulation have been frequently identified in multiple cancers, but the role of miR-340 and EZH2 in LSCC has not been explored. In this study, we investigated the regulative role of miR-340 in EZH2 expression...
Amyotrophic lateral sclerosis (ALS) is a neural disorder that causes death of the motor neurons in the brain and spinal cord; this affects the voluntary muscles and gradually leads to paralysis of the whole body. Most ALS cases are sporadic, though about 5–10% are familial. ALS is caused by multiple factors including mutation in any one of a number of specific genes, one of the most frequently affected...
Glaucoma is a common disease often identified by high intraocular pressure, characteristic optic neuropathy and vision loss. It is currently a leading cause of blindness worldwide with no known cure. Primary open angle glaucoma (POAG) is the most common type of glaucoma worldwide. It is a multifactorial disease where both genetic as well as environmental factors are involved in the pathogenesis.Till...
Endemic to the Sino-Himalayan subregion, the medicinal alpine plant Gentiana straminea is a threatened species. The genetic and molecular data about it is deficient. Here we report the complete chloroplast (cp) genome sequence of G. straminea, as the first sequenced member of the family Gentianaceae. The cp genome is 148,991bp in length, including a large single copy (LSC) region of 81,240bp, a small...
The development of the nervous system is based on the growth and connection of axons, and axon guidance molecules are the dominant regulators during this course. Robo, as the receptor of axon guidance molecule Slit, plays a key role as a conserved repellent cue for axon guidance during the development of the central nervous system. However, the function of Robo in the silkworm Bombyx mori is unknown...
The Nrf2–Keap1 pathway is crucial for the cellular antioxidant and hypoxia response in vertebrates. Deciphering its modifications in hypoxia-adapted animals will help understand its functionality under environmental stress and possibly allow for knowledge transfer into biomedical research. The blind mole rat Spalax, a long-lived cancer-resistant rodent, lives in burrows underground and is adapted...
Evidence indicates that let-7 of microRNA may be a prognostic factor in lung cancer. Genetic variation in microRNA precursors could influence the processing and expression of microRNAs, which could affect the prognosis of lung cancer. We aimed to investigate the impact of single nucleotide polymorphisms (SNPs) of pri-let-7 on the prognosis of non-small cell lung cancer (NSCLC).A total of 761 patients...
Zebrafish connexin 36.7 (cx36.7/ecx) has been identified as a key molecule in the early stages of heart development in this species. A defect in cx36.7 causes severe heart malformation due to the downregulation of nkx2.5 expression, a result which resembles congenital heart disease in humans. It has been shown that cx36.7 is expressed specifically in early developing heart cardiomyocytes. However,...
Axon guidance is critical for proper wiring of the nervous system. During the neural development, the axon guidance molecules play a key role and direct axons to choose the correct way to reach the target. Robo, as the receptor of axon guidance molecule Slit, is evolutionarily conserved from planarians to humans. However, the function of Robo in the silkworm, Bombyx mori, remained unknown. In this...
Insulin-like factor 3 (INSL3), secreted by the ovarian theca cells is involved in androgen production, follicular growth and oocyte maturation. Both androgens and INSL3 levels are reported to be elevated in women with polycystic ovary syndrome (PCOS), indicating that INSL3 could contribute to PCOS etiology. This case–control association study explored the impact of INSL3 polymorphisms on PCOS susceptibility...
Familial adenomatous polyposis (FAP) is mainly caused by germline mutations in the adenomatous polyposis coli (APC) gene. This study aimed to detect pathogenic variants in five Chinese FAP families and review all previously reported pathogenic variants of APC gene in Chinese population.Five non-consanguineous FAP families and 100 unrelated ethnicity-matched controls were included in the study. Sanger...
Homologs of the eukaryotic transcription coactivator PC4, which also functions in DNA repair and oxidative stress, were recently identified in prokaryotes. Crystallographic analysis of BPSL1147, a putative homolog from the pathogen Burkholderia pseudomallei K96243, reveals a highly conserved core structure and suggests a nucleic acid binding mode similar to that of PC4. Knock-out and complementation...
Campomelic dysplasia is a rare disorder characterized by skeletal and extraskeletal defects. Up to two-thirds of affected XY individuals have a gradation of genital defects or may develop as phenotypic females. This syndrome is caused by alterations in SRY-related HMG-Box Gene 9 (SOX9), a transcription factor essential in both chondrocyte differentiation and sex determination.We report a 27-week fetus...
ZKSCAN5 (also known as ZFP95) is a zinc-finger protein belonging to the Krűppel family. ZKSCAN5 contains a SCAN box and a KRAB A domain and is proposed to play a distinct role during spermatogenesis. In humans, alternatively spliced ZKSCAN5 transcripts with different 5′-untranslated regions (UTRs) have been identified. However, investigation of our Macaca UniGene Database revealed novel alternative...
MicroRNAs (miRNAs) play an important role in the modulation of various metabolic processes in the liver, yet little is known about the liver microRNAome (miRNAome) of the Tibetan pig. Here we used the Yorkshire pig as a control to analyze the Tibetan pig-specific liver miRNAome, and for preliminary investigation of differentially expressed miRNAs participating in metabolism. A comprehensive analysis...
The evolutionarily conserved nuclear export factor 1 (NXF1) provides mRNA export from the nucleus to the cytoplasm. We described several testis-specific transcripts of the Drosophila melanogaster nxf1 gene designated “sbr” in this species via different PCR approaches and CAGE-seq analysis. Characteristically, most of them have truncated 3′UTRs compared with those in other organs. In addition to regular...
Using longissimus dorsi muscles of Dorper sheep as the experimental materials, the complete cDNAs of ovine MYL3 (Myosin light chain 3) and MYL4 (Myosin light chain 4) genes were cloned using RT-PCR, 5′ RACE and 3′ RACE. We obtained 925-bp and 869-bp full-length cDNAs and submitted their sequences to GenBank as accession numbers of KJ710703 and KJ768855, respectively. The cDNAs contained 600-bp and...
Quercetin (Que), a plant-derived flavonoid, possesses various biological functions. Moreover, Que exerts multiple beneficial actions in treatment of cardiovascular diseases and there are an inverse association between Que intakes and occurrence and development of various cardiovascular diseases. Some researchers have inferred that the mechanisms of Que to protect cardiomyocytes from ischemia/reperfusion...
Herein, Nile tilapia thioredoxin-interacting protein (On-TXNIP) and selenoprotein P (On-SEPP) cDNAs were cloned and characterized. The full-length On-TXNIP cDNA contained 2 arrestin domains, 2 conserved cysteine residues that bind to thioredoxin to inhibit thioredoxin function, and 2 PPXY motifs, which negatively regulate the protein by stimulating binding to E3 ubiquitin ligase. The On-SEPP cDNA...
Congenital heart disease (CHD) is the most prevalent developmental abnormality in humans and is the most common non-infectious cause of infant morbidity and mortality. Increasing evidence demonstrates that genetic defects are involved in the pathogenesis of CHD. However, CHD is genetically heterogeneous, and the genetic determinants underpinning CHD in most patients remain unknown. In this study,...
