Abstract:
... BACKGROUND: Anorectal condyloma is the representative venereal disease caused by human papilloma virus (HPV), which has more 180 subtypes. Although there are various known risk factors for recurrence, few studies have investigated the influence of HPV subtypes. OBJECTIVE: We aimed to investigate the correlation between the recurrence of anorectal condyloma and HPV subtypes. METHODS: We analyzed th ...
... BACKGROUND: Glutamine-fructose-6-phosphate aminotransferase (GFPT) is a key factor in the hexosamine metabolism pathway. It regulates the downstream factor O-GlcNAc to change cell function and plays an important role in the metabolism and immune process of tissues and organs. However, the evolutionary relationship of GFPT family proteins in vertebrates has not been elucidated. OBJECTIVE: To deduce ...
... BACKGROUND: Sulfide is a well-known toxicant widely distributed in the culture environment. As a representative burrowing benthic bivalve, the razor clam Sinonovacula constricta is highly sulfide tolerant. Mitochondrial sulfide oxidation is an important way for sulfide detoxification, where sulfur dioxygenase (SDO) is the second key enzyme. OBJECTIVE: To investigate the mechanism of sulfide tolera ...
... BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a chronic lung disease and the third leading cause of death in the world. Dexmedetomidine has been reported to effectively inhibit histamine-induced bronchoconstriction. However, the molecular mechanism of dexmedetomidine in COPD has not been found. OBJECTIVE: To explore the role and mechanism of dexmedetomidine in COPD, and to provide th ...
... BACKGROUND: Ovarian development is regulated by genes that are expressed dynamically and stage-specifically. Circular RNA (circRNA) has been proven to play a significant role in the regulation of animal reproduction. OBJECTIVE: Studying the expression characteristics of circRNAs in goose ovaries at various egg-laying stages can provide a reference for the molecular regulation mechanism of ovary de ...
... BACKGROUND: Disheveled-associated activator of morphogenesis (DAAM) family, including DAAM1 and DAAM2, is key regulators in Wnt signaling pathway. Although the oncogenic role of Wnt signaling pathway in colorectal cancer (CRC) was investigated in several lines, the expression and function of DAAM in CRC are still obscure. OBJECTIVE: To investigate the expression and function of DAAM in CRC. METHOD ...
... BACKGROUND: Long non-coding RNAs (lncRNAs) are widely involved in gene transcription regulation and which act as epigenetic modifiers in many diseases. OBJECTIVE: To determine whether lncRNAs are involved in ischemic stroke (IS), we analyzed the expression profile of lncRNAs and mRNAs in IS. METHODS: RNA sequencing was performed on the blood of three pairs of IS patients and healthy controls. Diff ...
... BACKGROUND: Early growth response-1 (EGR1) is a transcription factor involved in the progression of several cancer types. However, the expression and clinical significance of EGR1 in uterine cervical cancer (CC) have not been elucidated. OBJECTIVE: To investigate the expression, clinical significance and prognostic value of EGR1 in CC. METHODS: The expression of EGR1 was detected in 13 CCs and pai ...

... BACKGROUND: Thymosin β4 (Tβ4) is a highly conserved actin binding protein associated with the metastatic potential of tumor cells by stimulating cell migration. The role of Tβ4 and its derived fragment peptides in migration of ovarian cancer cells has not been studied. OBJECTIVE: To analyze the effects of Tβ4 and its derived fragment peptides on ovarian cancer cell migration and invasion, we appli ...
... BACKGROUND: Short tandem repeats (STR) typing is an essential analysis method for human identification in forensic field. When DNAs obtained from the field as evidences are severely degraded or in too small amounts, STR analysis often shows allele drop-out. OBJECTIVE: To improve STR analysis for degraded DNA or trace DNA, reduced-size STR (rSTR) polymerase chain reaction (PCR) system was devised b ...
... BACKGROUND: Centromeres are specialized chromosomal domains involved in kinetochore formation and faithful chromosome segregation. Despite a high level of functional conservation, centromeres are not identified by DNA sequences, but by epigenetic means. Universally, centromeres are typically formed on highly repetitive DNA, which were previously considered to be silent. However, recent studies hav ...
... BACKGROUND: The centromere is the special region on a chromosome, which serves as the site for assembly of kinetochore complex and is essential for maintaining genomic integrity. Neocentromeres are new centromeres that form on the non-centromeric regions of the chromosome when the natural centromere is disrupted or inactivated. Although neocentromeres lack the typical features found in centromeres ...
