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]

AbstractHereditary mixed polyposis syndrome (HMPS) is a hereditary syndrome that is characterized by multiple colon polyps of mixed pathologic subtypes and an increased risk for colorectal cancer. A 40  kb duplication in the 5′ regulatory region of theGREM1 gene was recently found to be the causal mutation in a subset of Ashkenazi Jewish families with HMPS. Given this discovery, theGREM1 5 ′ regulatory region is now analyzed on many different multi-gene cancer panels, however the data on duplications distinct from the 40 kb duplication remains minimal. Herein we report a novel 24 kb tandem duplic...

The search for new diagnostic and therapeutic procedures is an essential task in contemporary oncology [1 –3]. The prevention of the development of gastrointestinal cancer, in particular the detection and resection of polyps, is the reason why screening endoscopy is conducted. Endoscopic methods are, and will continue to be, the gold standard diagnostic tool in the diagnosis of organic gastrointestina l diseases as, apart from the actual imaging of available sections of the gastrointestinal tract, they also allow for targeted biopsy of pathological changes.

Freenome is looking to build a diagnostic test that can learn from its mistakes. The South San Francisco, CA- based company is using artificial intelligence to improve colorectal cancer screening. To do this, Freenome has initiated AI-EMERGE, a clinical study for the AI-Genomics blood test, which will collect samples from up to 3,000 patients in the U.S. and Canada. Freenome CEO, Gabe Otte said the infusion of AI is a natural step in the evolution of diagnostics that should have been taken years ago. “If you look at the traditional molecular diagnostic tests that are out there – the PSA tests for example &ndash...

Pediatric gastrointestinal polyps are mostly benign1; however, further considerations are warranted in immune-compromised patients.2 Here, we report gastrointestinal polyposis with microsporidia infection in a five-year-old girl with human immunodeficiency virus (HIV) infection and poor therapy compliance. The mother was HIV positive and not on highly active anti-retroviral therapy (HART).

Conclusions: Compared with outpatients, the inpatients showed higher overall significant findings. Men undergoing MCE were younger than the women, and more likely to have ulcerations. Older patients, whether outpatient or inpatient, had higher rates of significant findings, mainly polyp and angiodysplasia.

Familial adenomatous polyposis is an autosomal dominant disorder characterized by development of hundreds of colorectal adenomas and eventually colorectal cancer. Oral administration of the spice curcumin has been followed by regression of polyps in patients with this disorder. We performed a double-blind, randomized trial to determine the safety and efficacy of curcumin in patients with familial adenomatous polyposis.
