Article Synopsis
  • Cancer treatment faces challenges due to the heterogeneity of tumors, as shown in a study of gastric adenocarcinoma (GA) using single-cell sequencing from 5 patients.
  • The research identified a specific type of cancer cell, CCKBR+, linked to worse patient outcomes and found that inhibiting certain factors (FOXOs) can reduce these aggressive cancer cells and tumor growth.
  • The study also discovered that FOXOs promote the activity of specific enzymes, enhancing a process called sialylation in CCKBR+ cells, which is crucial for their survival and growth, suggesting new targets for treatment strategies against this type of gastric cancer.

Background: Next-generation sequencing (NGS) is maturely applied for gene fusion detection. Although tumor fusion burden (TFB) has been identified as an immune marker for cancer, the relationship between these fusions and the immunogenicity and molecular characteristics of gastric cancer (GC) patients remains unclear. GCs have different clinical significance depending on their subtypes, and thus, this study aimed to investigate the characteristics and clinical relevance of TFB in non-Epstein-Barr-virus-positive (EBV+) GC with microsatellite stability (MSS).

Our study aimed at investigating how LINC01133 functions in gastric cancer (GC) progression. Gain-of-function and loss-of-function approaches were applied to analyze the effects of LINC01133, microRNA-576-5p (miR-576-5p) and somatostatin (SST) on the biological behaviors of GC cells and in tumor-bearing nude mice. GC tissues and cells showed low expression of LINC01133, and LINC01133 overexpression decreased malignant phenotypes of GC cells.

Tumour protein translationally controlled 1 (TPT1) antisense RNA 1 (TPT1-AS1) is known to be involved in the development and metastasis of cervical and ovarian cancers; however, its biological role in colorectal cancer (CRC) remains unknown. This study aimed to determine the function and mechanism of action of TPT1-AS1 in the progression and metastasis of CRC. Elevated TPT1-AS1 levels were observed in CRC tissues.

To explore the efficiency and safety of laparoscopic anus-conserving operation for ultralow rectal cancer, we retrospectively reviewed 236 patients with ultralow rectal cancer who underwent laparoscopic anus-conserving operation (experimental group, n = 124) or conventional open surgery (control group, n = 112). Operation-related indexes, pathological results of mesentery, incidence rates of postoperative complications, anus preservation rates, anal sphincter controllability after surgery, and survival rates of the first, second, and third years after operation were compared between the two groups. The amount of intraoperative bleeding, first postoperative exhaust time, abdominal drainage, pain score, and hospital stay in the experimental group were significantly less than those in the control group ( < 0.

It is of great value to develop general, low-cost and even household methods for colorectal cancer detection. Here, a portable detection strategy based on a personal glucose meter (PGM) was designed for meeting this purpose. In this strategy, the anti-EpCAM coated magnet beads (MBs) were used as capture probes for enriching cancer cells and the aptamer modified and invertase loaded graphene oxides (GO) were used as report probes for producing glucose signal.

Aim: To compare the results of total laparoscopic distal gastrectomy (TLDG) and laparoscopy-assisted distal gastrectomy (LADG) and explore the safety and feasibility of TLDG.

Methods: Data were collected and analyzed from patients underwent TLDG and LADG from January 2009 to December 2011 at our institution.

Results: 127 LADG cases and 104 TLDG cases were included and balanced for age, sex, BMI, ASA scores, and CEA level in this study.

Long noncoding RNA serves important roles in gastric cancer (GC). However, the prognostic significance and tumorigenesis effect of AFAP1-antisense RNA 1 (AS1) in GC remain to be clarified. The present study was conducted in order to determine the expression level of AFAP1-AS1 by reverse transcription-quantitative polymerase chain reaction.

Colorectal carcinoma (CRC) is one of the most common cancers in the world, and identification of new CRC biomarkers will be helpful for the diagnosis and treatment of CRC. For isobaric tags for relative and absolute quantitation (iTRAQ) analysis, fresh CRC and adjacent, colonic adenoma, ulcerative colitis, Crohn's disease, and noncancerous colonic epithelial tissue were obtained from patients at the 2nd Xiangya Hospital of Central South University, China. The function of heterogeneous nuclear ribonucleoprotein M (HnRNP M) during the proliferation, invasion, and metastasis of CRC cells in vitro was evaluated.

Objective: To explore the laparoscopic partial gastrectomy and the indications.

Methods: Eighteen patients who underwent laparoscopic partial gastrectomy from August 2005 to May 2006 were analyzed retrospectively.

Results: Sixteen patients (including 6 with gastric cancer, 9 with duodenal ulcer, and 1 with gastric multiple polyps) underwent laparoscopic partial gastrectomy.
