Here, the clinicopathological and immunohistochemical characteristics of calretinin-positive lung cancer were examined to reduce confusion with malignant mesothelioma. Calretinin expression in 307 consecutive cases of lung cancer was evaluated immunohistochemically. Survival was analyzed using the Kaplan–Meier method and log-rank test. Calretinin expression was identified in 67 (22%) tumors, including those with partial and weak expression [15% (37/250) of adenocarcinomas, 54% (25/46) of squamous cell carcinomas, 75% (3/4) of adenosquamous carcinomas, and 29% (2/7) of sarcomatoid carcinomas]. In calretinin-positive adenocarcinoma (n = 37), expression percentages of Wilms tumor-1, podoplanin, thyroid transcription factor-1, and claudin-4 were 6, 3, 52, 82%, respectively, whereas in calretinin-positive squamous cell carcinoma (n = 25) the percentages were 8, 12, 12, 68%, respectively, indicating that other mesothelial markers were only rarely expressed and that claudin-4 expression was common. Although not an independent marker, calretinin expression was associated with a ...

ConclusionNEAT1 upregulateIGF2 expression through absorbing miR ‐185‐5p to enhances the migration and invasion of colon cancer cells.
ConclusionOur results suggest that the combination of altered expression of genes involved in signaling pathways of immune response and apoptosis control may contribute directly to the main characteristics observed in BS, such as recurrent infections, growth failure, and high risk of cancer. Transcriptome studies of other instability syndromes could allow a more accurate analysis of the relevant gene interactions associated with the destabilization of the genome. This is a first description of the profile of differential gene expression related to immunological aspects detected in patients with BS by RNA ‐seq.
Helicobacter pylori is one of the most prevalent infection worldwide. It affects individuals of different age groups. Aging ‐associated risk factors should be considered. Future studies, related to aging andH. pylori infection with extragastric disease can help to provide vivid evidences. AbstractHelicobacter pylori is one of the most prevalent infection worldwide. It affects individuals of different age groups. Elderly people tend to resist eradication treatment and worsening of infection can lead to several gastric and non ‐gastric pathologies. Aging‐associated cellular and molecular alteration can increase the ris...
ConclusionIn summary, the above results indicate thatXIST promotes colorectal cancer tumorigenesis by regulating miR ‐93‐5p/HIF ‐1A/AXL signaling pathway, which will supply a novel perspective to diagnose and treat colorectal cancer disease.

ConclusionChronic inflammation in the dorsolateral prostate of rats dosed with EB, T and E resulted in deregulated expression in a set of microRNAs whose target genes were related to tumor growth or abnormal proliferation. Our findings suggest the identified microRNAs and their target genes the potential use as biomarkers to predict prostate cancer development. Validation using human samples is warranted.
Discussion and conclusionsA schema showing the time from initiation of therapy at which specific antineoplastic agents can cause significant levels of genetic damage in conceptuses and live offspring was developed. The estimates and methods for computing the level of such risk from an individual patient's treatment regimen will enable patients and counselors to make informed decisions on the use of spermatozoa or continuation of a pregnancy.

INTRODUCTION: Long-term childhood cancer survivors (CCS) are at risk for physical and psychosocial late effects. Previous research has attested to increased rates of suicidal ideation (SI) in CCS, an especially dangerous indicator of distress. However, lit...
