Identification of RE1-Silencing Transcription Factor as a Promoter of Metastasis in Pancreatic Cancer

In conclusion, our results of bioinformatic analysis, in vitro and in vivo functional analysis suggested that REST may serve as a promoter of metastasis in pancreatic cancer. Introduction Pancreatic cancer, ranked fourth in cancer-related mortality, is characterized by its rapid progression and early metastasis (1). Patients are hardly cured by surgical resection due to the existing local invasion and distant metastasis (2). Elevating the overall survival rate for pancreatic cancer requires further elucidation of the underlying molecular mechanism of its metastasis. Epithelial-mesenchymal transition (EMT), especially type III EMT, is reported to be one of the primal steps for cancer cells' local invasion and distant metastasis (3, 4). It is a complicated process in which cancer cells transit from a rather dominant epithelial phenotype to a more invasive and metastatic mesenchymal phenotype (5). This process is characterized by alterations in the expression level of multiple proteins leading to the loss of cell junctions and apical-basal polarity in cancer cells. Therefore, identification of key genes regulating EMT and cancer metastasis possesses great clinical significance (6). These genes could be predictive biomarkers for cancer metastasis and novel therapy targets for anti-cancer drugs. The Cancer Genome Atlas (TCGA) is a comprehensive cancer genomic database (7). All of its cancer tissue and matched normal tissue samples were collected and further analyzed...

Germà LluchAbstractRecent epidemiological studies have shown that alcohol consumption can increase the risk of arterial hypertension, atrial fibrillation and gastrointestinal and breast cancer. Various sectors are therefore promoting abstinence from alcohol. However, light alcohol consumption has once again been shown to reduce the risk of myocardial infarction and diabetes but with an unclear effect on cerebrovascular disease. The decision to consume alcohol should therefore be ...

Publication date: Available online 17 August 2019Source: Surgery (Oxford)Author(s): Tim LaneAbstractUpper tract transitional cell carcinoma is a lethal disease with half the patients dead within 5 years of diagnosis. Unlike urothelial tumours arising in the bladder, the disease is more likely to be invasive at the time of diagnosis and in part reflects the poorer prognosis. It is a biologically aggressive disease with a high chance of recurrence even after local control. Diagnosis is made by a combination of upper tract imaging, urine cytology and ureteroscopic biopsy. Organ-confined disease is amenable to radical surgery,...

This review examines the current standards in the diagnosis and management of this disease. Cystoscopy and urine cytology remain important tools in the diagnosis and follow-up of bladder cancer. Alternatives include photodynamic diagnosis, narrow band imaging and professional image enhancement which may improve detection of tumours. En-bloc resection using either laser or electrocautery shows p...

ConclusionPrimary hepatic ACC may easily be confused for other lesions due to nonspecific imaging patterns. Specifically, the presence of a central scar without risk factors for HCC can favour a diagnosis of benign entities such as focal nodular hyperplasia (FNH). Electron microscopy presents an important tool to identify primary hepatic ACC and may improve future patient outcomes.

ConclusionWe found no evidence that Donders contracted leprosy despite years of intense leprosy contact, but we successfully isolated an archaeological M. leprae aDNA sample from a control skeleton from South America.SignificanceWe successfully genotyped recovered aDNA to a M. leprae strain that likely originated in West Africa. The detected human mitochondrial haplogroup L3 is also associated with this geographical region. This suggests that slave trade contributed to leprosy in Suriname.LimitationsA limited number of skeletons was examined.Suggestions for further researchBroader review of skeletal collections is advised ...
