Canine mammary cancer in overweight or obese female dogs is associated with intratumoral microvessel density and macrophage counts.

Obesity is a major health condition owing to its effects on chronic diseases and cancers in humans, but little information is available regarding the role of obesity in canine mammary cancer (CMC). In the present study, we performed immunohistochemistry to investigate the effect of obesity on CMC by analyzing the number of tumor-associated macrophages, intratumoral microvessel density (iMVD), and the expression of prognostic factors including epidermal growth factor receptor (EGFR), cyclooxygenase 2 (COX-2), and Ki67 in CMC specimens. These data were compared in CMC specimens from lean or ideal body weight (Group 1) versus overweight or obese (Group 2) female dogs ( = 60 for each group).

Arginase-1 and P-glycoprotein are downregulated in canine hepatocellular carcinoma.

Background: Hepatocellular carcinoma is the most common primary hepatic malignancy in humans and dogs. Several differentially expressed molecules have been studied and reported in human hepatocellular carcinoma and non-neoplastic liver lesions. However, studies on the features of canine hepatocellular carcinoma are limited, especially related to the differential characteristics of neoplastic and non-neoplastic lesions.

Tumour necrosis factor-related apoptosis-inducing ligand (TRAIL) loss in canine mammary carcinoma.

Escaping apoptosis is a hallmark of cancer. Tumour necrosis factor-related apoptosis-inducing ligand (TRAIL), a central molecule that regulates the extrinsic apoptotic pathway, has been widely investigated in human oncology; however, investigations focusing on the endogenous expression of TRAIL in canine tumours are lacking. Therefore, we aimed to examine the expression of endogenous TRAIL in canine mammary tumours and analysed its correlation with downstream molecules Fas-associated protein with death domain (FADD) and caspase-3, and to the apoptotic index.

Impact of Histological Subtype on Survival in Canine Mammary Carcinomas: a Retrospective Analysis of 155 Cases.

Canine mammary carcinoma (CMC) is the most common type of neoplasm in intact female dogs. While a previous study in Western countries validated the 2011 classification as an independent prognostic indicator in CMC, its role in CMC prognostication in Asian countries such as Korea remains unclear. In the present study, we estimate the survival rates in CMC types defined by the 2011 classification, elucidate the prognostic significance of the histological subtype and grade and that of the lymphatic invasion status in CMC, and validate the 2011 classification as an independent prognostic indicator in a large cohort of CMCs (excluding cases of multicentric CMCs).

In situ c-KIT mRNA quantification of canine cutaneous mast cell tumours and its relationship to prognostic factors.

Cutaneous mast cell tumours (MCTs) are the most frequent malignant skin tumours in dogs. Mutations in the c-KIT proto-oncogene are correlated with the pathogenesis and aggressiveness of MCTs. To date, studies have focused on c-KIT mutations and KIT protein localization, with a general lack of mRNA-level analyses.

Amentoflavone, active compound of Selaginella tamariscina, inhibits in vitro and in vivo TGF-β-induced metastasis of human cancer cells.

Epithelial mesenchymal transition (EMT) is a well-known and important step in metastasis and thus can be a key target in cancer treatment. Here, we tested the EMT inhibitory actions of Selaginella tamariscina and its active component, amentoflavone (AF). EMT was examined in vitro using wound-healing and invasion assays and by monitoring changes in the expression of the EMT-related proteins, E-cadherin, Snail, and Twist.

Hypoxia-responsive folic acid conjugated glycol chitosan nanoparticle for enhanced tumor targeting treatment.

Hypoxia is a characteristic feature of various ischemic diseases, including cancer. This study describes the development of glycol chitosan nanoparticles, hydrophobically modified with 4-nitrobenzyl chloroformate and folic acid (FA), that can specifically release drugs under hypoxic conditions. This hypoxia-responsive glycol chitosan nanoparticle conjugated with FA (HRGF) possesses tumor-targeting properties by virtue of conjugated FA and is able to release drugs in a nitroreductase (NTR)-dependent manner because its structure is cleaved by NTR under hypoxic conditions.

Quantitative analysis of HER2 mRNA expression by RNA in situ hybridization in canine mammary gland tumors: Comparison with immunohistochemistry analysis.

Spontaneously occurring canine mammary gland tumors share many features with human breast cancer, including biological behavior and histologic features. Compared to transgenic murine model, canine models have advantages including naturally occurring models of human diseases and cancer. In humans, breast cancer is divided into molecular subtypes based on ER, PR, and HER2 expression.
