Multicystic peritoneal mesothelioma: A short review.

Multicystic peritoneal mesothelioma (MCPM) is a rare neoplasm, predominantly affecting female patients during their reproductive years. The lesion is usually distributed diffusely in the abdomen and pelvis, but the peritoneum of the pelvic organs is the most common site. MCPM is composed of fluid-filled translucent cysts, connected by varying amounts of fibrous tissue, and lined by a layer of mesothelial cells.

Bone marrow-derived mesenchymal stem cells increase drug resistance in CD133-expressing gastric cancer cells by regulating the PI3K/AKT pathway.

Bone marrow-derived mesenchymal stem cells (BM-MSCs) are recruited to primary tumours to compose the tumour microenvironment. In various cancers, CD133-positive cells have been shown to possess cancer stem cell properties that confer chemoresistance. This study aimed to investigate the role of BM-MSCs in the anti-tumour drug resistance of CD133-expressing gastric cancer cells and explore the underlying mechanisms that governing this role.

Evidence of Apis cerana Sacbrood virus Infection in Apis mellifera.

Sacbrood virus(SBV) is one of the most destructive viruses in the Asian honeybee Apis cerana but is much less destructive in Apis mellifera In previous studies, SBV isolates infecting A. cerana(AcSBV) and SBV isolates infecting A. mellifera(AmSBV) were identified as different serotypes, suggesting a species barrier in SBV infection.

Contactin 1: A potential therapeutic target and biomarker in gastric cancer.

Despite advances in diagnosis and treatment, gastric cancer remains one of the most common malignant tumors worldwide, and early diagnosis remains a challenge. The lack of effective methods to detect these tumors early is a major factor contributing to the high mortality in patients with gastric cancer, who are typically diagnosed at an advanced stage. Additionally, the early detection of metastases and the curative treatment of gastric cancer are difficult to achieve, and the detailed mechanisms remain to be fully elucidated.

Significances of contactin-1 expression in human gastric cancer and knockdown of contactin-1 expression inhibits invasion and metastasis of MKN45 gastric cancer cells.

Purpose: Contactin-1 (CNTN-1) has been shown to promote cancer metastasis. Previously, we have reported that the expression of CNTN-1 was upregulated in gastric cancer tissues compared with adjacent normal tissues. Here, we investigated the significance of CNTN-1 expression and its underlying mechanism of metastasis mediated by epithelial-mesenchymal transition (EMT) in gastric cancer.

Expressions and clinical significances of c-MET, p-MET and E2f-1 in human gastric carcinoma.

Background: To investigate on the expressions and the clinical significances of hepatocyte growth factor receptor (c-MET), phosphorylated c-MET (p-MET) and e2f-1 transcription factor in primary lesion of gastric adenocarcinoma (GC).

Method: Tissue samples from the primary lesion of GC in patients who accepted D2/D3 radical gastrectomy with R0/R1 resection were stained by immunohistochemistry of c-MET, p-MET, e2f-1 and Ki-67. The univariate and the multivariate analyses involving in clinicopathological parameters and prognostic factors were evaluated.

Methods: CD133(+) cells of KATO-III cell lines were isolated by magnetic activated cell sorting (MACS). CD133 siRNA was designed and synthesized, and then transfected into KATO-III CD133(+) cells.

[CD133 promotes the invasion and metastasis of gastric cancer via epithelial-mesenchymal transition].

Objective: To examine the association between CD133 expression and invasion of gastric cancer, and to elucidate whether CD133 can promote the invasion and metastasis of gastric cancer via epithelial-mesenchymal transition (EMT).

Methods: The CD133(+) and CD133(-) KATO-III( cells were sorted by magnetic activated cell sorting (MACS). The invasion ability was detected by Transwell method.
