Overweight/obesity-related transcriptomic signature as a correlate of clinical outcome, immune microenvironment, and treatment response in hepatocellular carcinoma.

Backgrounds: The pandemic of overweight and obesity (quantified by body mass index (BMI) ≥ 25) has rapidly raised the patient number of non-alcoholic fatty hepatocellular carcinoma (HCC), and several clinical trials have shown that BMI is associated with the prognosis of HCC. However, whether overweight/obesity is an independent prognostic factor is arguable, and the role of overweight/obesity-related metabolisms in the progression of HCC is scarcely known.

Materials And Methods: In the present study, clinical information, mRNA expression profile, and genomic data were downloaded from The Cancer Genome Atlas (TCGA) as a training cohort (TCGA-HCC) for the identification of overweight/obesity-related transcriptome.

Role of RNA-interference-induced zinc finger protein 139 suppression in gastric cancer cell sensitivity to chemotherapeutic agents.

Zinc finger proteins (ZNFs) are a class of proteins widely distributed in the human genome, which have been found to play a role in the regulation of gene transcription and the occurrence and development of gastric cancer (GC). ZNF139 was found to be associated with GC in our previous experiments. The present study aimed to analyse the differences in ZNF139 protein expression in SGC7901 GC cells and in situ grafted GC tumors in nude mice prior to and following RNA interference inhibition, and to investigate the mechanisms underlying ZNF139 involvement in the occurrence, development and chemosensitivity of GC.

[Effect and mechanisms of TET on human gastric carcinoma cell line SGC7901 and SGC7901/ADR].

Objective: To investigate the effect of tetrandrine (TET) on zinc finger protein 139 (ZNF139) and multidrug resistance (MDR) of human gastric carcinoma cell lines and possible mechanisms.

Methods: Cultured SGC7901 and SGC7901/ADR were treated with TET (0.5, 1.

[Effects of XELOX regimen as neoadjuvant chemotherapy on radical resection rate and prognosis in patients with advanced gastric cancer].

Objective: The purpose of this study was to investigate the efficacy and mechanism of oxaliplatin in combination with capecitabine (XELOX) regimen as neoadjuvant chemotherapy in the treatment of patients with advanced gastric cancer.

Methods: Eighty-five patients with advanced gastric cancer (stage IIB and IIIC) were randomly divided into two groups: neoadjuvant chemotherapy group (40 cases) and surgery alone group (45 cases). In the neoadjuvant chemotherapy group, patients received oral administration of Xeloda 1000 mg/m(2) twice a day on days 1-14 and intravenous infusion of oxaliplatin 130 mg/m(2) on day 1 (XELOX regimen).

Histological complete response after neoadjuvant XELOX in advanced gastric carcinoma.

We report on a case of a 65-year-old Chinese male with locally advanced gastric adenocarcinoma achieving pathological complete response after neoadjuvant chemotherapy with capecitabine and oxaliplatin (XELOX) regimen. He underwent esophagogastroduodenoscopy, which revealed a 6x5cm gastric ulcer. Biopsy of gastric ulcer revealed adenocarcinoma.

[Effect of local application of allicinvia gastroscopy on cell proliferation and apoptosis of progressive gastric carcinoma].

Objective: To study the effects of local application of allicin via gastroscopy on progressive gastric carcinoma, and to investigate its possible mechanisms.

Methods: Eighty patients with progressive gastric adenocarcinoma, whose diagnosis was confirmed by gastroscopy and pathological examination, were assigned to 2 groups, 40 in each group. Forty-eight hours before operation, allicin was infused via gastroscopy to the lesion region of patients in the allicin group, and normal saline was infused instead to those in the control group.

[Detecting bone marrow micrometastasis of gastric cancer by magnetic activated cell sorting combined with fluorescent activated cell sorting].

Background & Objective: Several methods are used to detect bone marrow micrometastasis of gastric cancer with different accuracies. In breast cancer, tumor cells in blood can be detected sensitively and specifically by magnetic activated cell sorting (MACS) and fluorescent activated cell sorting (FACS). This study was to investigate the clinical value of this method in detecting bone marrow micrometastasis of gastric cancer.

[Drug distribution in gastric cancer and adjacent tissues by preoperative intraperitoneal chemotherapy with Co-fluorouracil liposome].

Objective: To examine the distribution of fluorouracil in gastric cancer (CA), lymph node (LN), normal gastric mucosa (NG), peritoneum (PE), greater omentum (GO) and lesser omentum (LO) by preoperative intraperitoneal chemotherapy with Co-fluorouracil liposome (Co 5-Fu), and offer an experimental basis for clinic practice.

Methods: Ninety-six gastric cancer patients were divided into four groups: Co 5-Fu i.v.

[Expression of MUC1, CD44v6, nm23 in gastric carcinomas and regional lymph node tissues and their association with invasion, metastasis, and prognosis of the tumor].

Background & Objective: The invasion depth and lymph node metastasis result from the polygenes and their protein expression in gastric carcinoma. The key of the basic and clinical research of the gastric carcinoma is to find out the related molecular biology marker. This study was designed to investigate the relationship between the expression of MUC1, CD44v6, nm23 in gastric carcinomas and regional lymph node tissues and invasion, metastasis, and prognosis of the tumor.
