MiR-1301-3p Inhibits Epithelial-Mesenchymal Transition via Targeting RhoA in Pancreatic Cancer.

Micro(mi)RNAs play an essential role in the epithelial-mesenchymal transition (EMT) process in human cancers. This study aimed to uncover the regulatory mechanism of miR-1301-3p on EMT in pancreatic cancer (PC). The miRNA profilings from Gene Expression Omnibus data sets (GSE31568, GSE41372, and GSE32688) demonstrated the downregulation of miR-1301-3p in PC tissues, which was validated with 72 paired PC tissue samples through qRT-PCR detection.

Single-cell transcriptomics reveals heterogeneous progression and EGFR activation in pancreatic adenosquamous carcinoma.

Pancreatic adenosquamous carcinoma (PASC) - a rare pathological pancreatic cancer (PC) type - has a poor prognosis due to high malignancy. To examine the heterogeneity of PASC, we performed single-cell RNA sequencing (scRNA-seq) profiling with sample tissues from a healthy donor pancreas, an intraductal papillary mucinous neoplasm, and a patient with PASC. Of 9,887 individual cells, ten cell subpopulations were identified, including myeloid, immune, ductal, fibroblast, acinar, stellate, endothelial, and cancer cells.

Results: Compared to the control group, patients with soft pancreas in the enhanced recovery after surgery group had a lower incidence of delayed gastric emptying (36.

Circ_0005075 promotes hepatocellular carcinoma progression by suppression of microRNA-335.

Accumulating evidence suggests that noncoding RNAs play a vital role in cancer biology. Circular RNAs (circRNAs), a newly defined class of endogenously widespread noncoding RNAs, have been intensively reported to influence cell function and development, and even cancer prognosis by sponging microRNAs in various types of cancer. Nevertheless, the circRNAs research in hepatocellular carcinoma (HCC) still remains far insufficient.

This paper discusses variations of laparoscopic transgastric cystogastrostomy in management of retrogastric pancreatic pseudocysts for 8 patients with symptom or pseudocysts (larger than 6 cm) companied with clinical manifestations. Using a Harmonic scalpel, two 3-5-cm incisions were made in the anterior and posterior gastric wall respectively. In the last step, the anterior gastrotomy was closed with an Endo-GIA stapler.

Isolated hepatic tuberculosis in the caudate lobe mimicking intrahepatic carcinoma.

Although tuberculosis (TB) remains a worldwide epidemic, isolated hepatic TB is an extremely rare entity and poorly described in the literature. Isolated hepatic TB may pose a diagnostic dilemma due to the non-specific clinical symptoms and imaging features. We present a case of a 54-year-old female with an isolated caseating granulomatous lesion at the caudate lobe of liver involving the pancreatic head.

Protective role of berberine and Coptischinensis extract on T2MD rats and associated islet Rin‑5f cells.

The aim of the present study was to compare the different effects of berberine (Ber) and Coptischinensis extract (CCE) on a rat model of type 2 diabetes mellitus (T2DM), and the islet Rin‑5f cell line was used to examine the differences between Ber and CCE and the underlying mechanisms. CCE was extracted and purified prior to analysis. Male Sprague‑Dawley rats were provided with a high‑fat diet to induce insulin resistance prior to injecting with streptozotocinto establish the T2DM model, the T2DM rats were treated with Ber and CCE, and blood samples and pancreatic tissues were obtained and compared to examine T2DM metabolic syndromes among the groups of rats, which included healthy rats, model rats, and model rats treated with Ber and CCE at different doses between 0 and 8 weeks.
