Eighty-one mixed breed intact male dogs were divided into three groups: Group 1 = left testicle biopsied by Trucut needle method (n=36); Group 2 = left testicle biopsied by Incisional method (n = 39); Group 3 = not biopsied (n = 6). The dogs were castrated 1 to 36 d following biopsy. The biopsy specimens and both testicles were examined for gross and histologic lesions. There was no effect of biopsy on testicle circumference. There was a positive correlation (r(2) = 0.93) between testicular circumference and occurrence of lesions. Incisional biopsies induced more gross lesions (67 vs 33%), and more histologic lesions (135 vs 43). The histologic lesions included hypospermatogenesis, coagulation necrosis, tubular degeneration, interstitial fibrosis and inflammation. In addition, the lesions observed in Incisional biopsy specimens were of greater severity and incidence than Trucut biopsy specimens (87 vs 35%). It was concluded that Incisional biopsy induced an increase in frequency and severity of lesions compared with Trucut biopsy of the canine testicle.

Gastroenterology and Liver Diseases Research Center, Research Institute for Gastroenterology and Liver Diseases, Shahid Beheshti University of Medical Sciences, Tehran, Iran.
Introduction: Colorectal cancer (CRC) is the second most common cause of cancer-related deaths globally. The gut microbiota, along with adenomatous polyps (AP), has emerged as a plausible contributor to CRC progression. This study aimed to scrutinize the impact of the FadA antigen derived from Fusobacterium nucleatum on the expression levels of the ANXA2 ceRNA network and assess its relevance to CRC advancement.

Intercellular TIMP-1-CD63 signaling directs the evolution of immune escape and metastasis in KRAS-mutated pancreatic cancer cells.

Department of Physiology, College of Medicine, National Cheng Kung University, Tainan, Taiwan.
Background And Aims: Oncogenic KRAS mutations are present in approximately 90% of pancreatic ductal adenocarcinoma (PDAC). However, Kras mutation alone is insufficient to transform precancerous cells into metastatic PDAC. This study investigates how KRAS-mutated epithelial cells acquire the capacity to escape senescence or even immune clearance, thereby progressing to advanced PDAC.
