Adiponectin is secreted by adipocytes and is a key hormone responsible for insulin sensitization. Recent studies have shown that plasma adiponectin is decreased in patients with breast, endometrial and gastric cancer. However, the effect of adiponectin on colorectal carcinogenesis is controversial. It is now well known that the adiponectin receptor exists in two isoforms, adiponectin receptor 1 (AdipoR1) and adiponectin receptor 2 (AdipoR2). We examined the expression of the adiponectin receptors on normal colon mucosa and colon cancer tissues in a human study using real-time RT-PCR, Western blotting and immunohistochemical staining. Adiponectin receptors, AdipoR1/AdipoR2, were expressed in normal colon epithelial and colon cancer cells. Furthermore, laser microdissection was performed to confirm our results. These results suggest that adiponectin may exert some effects on normal colon epithelium or colon cancer cells directly through adiponectin receptors. Further studies are required to elucidate the function of the AdipoRs activated by adiponectin and the downstream mechanisms of AdipoRs in colon cancer cells.

Many lines of evidence suggest that circular RNAs (circRNAs) are closely associated with the occurrence and progression of colon cancer. The objective of this study was to investigate the regulatory effects and mechanisms of circ_0075829 on ferroptosis and immune escape in colon cancer. We utilized colon cancer cell lines and a xenograft mouse model to analyze the function of circ_0075829 in vitro and in vivo.

Objective: To investigate the efficacy of laparoscopic sigmoid extraperitoneal colostomy combined with pelvic peritoneal closure in abdominoperineal resection for low rectal cancer.
Methods: We retrospectively analyzed the clinical data of 162 patients with low rectal cancer, who underwent laparoscopic abdominoperineal resection from January 2015 to January 2019 at the Affiliated Peace Hospital of Changzhi Medical College. Extraperitoneal stoma construction was performed in 98 patients (study group), while 64 patients (control group) underwent the procedure without suturing the pelvic peritoneum.

The discovery at the end of the 20th century of genes that induce cell death revolutionised the biocontaintment of genetically manipulated bacteria for environmental or agricultural applications. These bacterial 'killer' genes were then assayed for their potential to target and control malignant cells in human cancers. The identification of the bacteriomes in different human organs and tissues, coupled with the observation that bacteria tend to accumulate near tumours, has opened new avenues for anti-cancer strategies.

Background: Orthotopic murine models of pancreatic cancer represent an important tool for evaluating treatment strategies. Several genetically modified mouse tumors and xenograft models have been reported. Genetic models have unpredictable growth and variable waiting period, while orthotopic models are operative ones, difficult to create and result in irregular metastasis.

Background: Multimodal treatment involving preoperative chemoradiotherapy (CRT) followed by surgery is the current standard of care for rectal cancer. Despite advancements, the risk of recurrence, metastasis, and decreased survival remains high. This study aims to evaluate potential biomarkers to stratify prognosis in patients with rectal cancer undergoing preoperative CRT and surgery.
