Differentially expressed Secretoglobin 1C1 gene in nasal polyposis.

In this study, to determine the relationship between the Secretoglobin 1C1 gene promotor polymorphisms and the gene expression, the levels of 48 subjects were sequenced (24 patients with NP and 22 controls without sinonasal disease). The levels' expression of Secretoglobin 1C1 in the subjects' nasal mucosa was also detected using RT-PCR.  In this study, the level of Secretoglobin 1C1's expression increased in NP (P= 0.003). Three polymorphisms were detected in the Secretoglobin 1C1 gene's promotor. The rs113795008 and rs2280540 variations were significantly high in NP (P= 0.005, P= 0.045). The the rs113795008 homozygous mutant type genotype (G/G) was associated with a high mRNA expression level of Secretoglobin 1C1 in NP (P= 0.009). A correlation was found between a high level of Secretoglobin 1C1 expression and its promotor polymorphism, which thus might increase and/or contribute to the susceptibility of developing NP in the Turkish population. These findings suggested that promotor variations in the function of the Secretoglobin 1C1 gene can alter the gene expression biology in NP. PMID: 29412801 [PubMed - in process]

Conclusions Polyp size does not predict extrauterine disease for USC patients with disease in polyp only or disease in polyp and endometrium. Further study is needed to investigate whether presence of LVI is a prognostic factor.

Authors: Wang Y, Wang ZF, Zhang Z, Su Y Abstract The current study measured the expression of Clara cell 10-kDa protein (CC10) and trefoil factor family 1 (TFF1) in the sinus mucosa of patients exhibiting chronic rhinosinusitis (CRS) and nasal polyps (NP). CC10 and TFF1 expression in the sinus mucosa of the control group and patients with CRS and NP was determined using reverse transcription-quantitative polymerase chain reaction (RT-qPCR), western blotting and immunohistochemistry. The correlation between CC10 and TFF1 expression was further analyzed using Spearman's correlation analysis. The expression of TFF1 wa...

Conclusion Our survey confirms that nowadays the focus of treating intrauterine pathology is on less invasive techniques and preserving the uterus. Dutch responding hysteroscopists have more expertise concerning office hysteroscopy than their Flemish colleagues. Future research on the cost-effectiveness of and optimisation of patient comfort during office hysteroscopy is needed to support its further implementation.

Conclusions: Prevalence of polyps and adenomas differs based on colonoscopy indication. Adenoma detection is highest in surveillance and more commonly detected in the proximal colon. For quality assurance, distinct ADR and PDR targets may need to be established for different colonoscopy indications. PMID: 29445393 [PubMed]
