Tumors in oral cavity either benign or malignant are often found in dogs. Despite the increasing number of studies of gene expression associated with canine oral cavity diseases, reference gene selection for normalizing target genes has not been performed. The objective of the present study was to identify potential reference genes in canine oral tumors, including epulis, ameloblastoma, oral melanoma, oral squamous cell carcinoma, etc. Suitability of 6 candidate reference genes, beta-actin (ACTB), beta-2-microglobulin (B2M), glyceraldehydes-3-phosphate dehydrogenase (GAPDH), ribosomal subunit L13a (RPL13a), ribosomal protein S5 (RPS5) and ribosomal protein S19 (RPS19), was evaluated with 5 algorithms, geNorm, Normfinder, BestKeeper, the …

The aim of this retrospective study was to evaluate changes in electrocardiograms (ECG) and cardiac arrhythmias in 29 dogs with degenerative mitral valve disease (DMVD) treated with pimobendan chronically. All dogs had normal ECG before pimobendan administration. The dogs were classified according to ECG after pimobendan administration into 2 groups: normal ECG (n=19) and abnormal ECG (n=10). Age, sex, breed, serum alkaline phosphatase, concurrent digoxin administration, total daily dosage of pimobendan and digoxin, duration of pimobendan administration, and ECG parameters including heart rate, P wave, PR interval, QRS complex, and QT interval were analyzed. Cardiac arrhythmias were increasingly found in …

Involucrin (INV) is a cornified envelope precursor protein that is commonly used as an early stage marker of human terminal keratinocyte differentiation. This research investigated the expression of INV in canine skin tumors using 56 formalin-fixed paraffin-embedding (FFPE) biopsied specimens. The expression of INV was investigated by immunohistochemistry (IHC) and RT-PCR. Correlation between INV and Ki-67 was also performed. The malignant tumor groups showed significantly different INV staining scores and Ki-67 positive cells than the normal skin group by IHC (p<0.05). The INV scores of moderately differentiated SCC (MSCC), trichoblastoma (TCB), basal cell carcinoma (BCC) and poorly differentiated SCC (PSCC) significantly decreased, with a statistically significant difference (p<0.05). Interestingly, the INV of poorly differentiated SCC disappeared in some specimens. The INV expression in most tumors was found to be inversely proportionate to Ki-67 positive cells. In addition, only SCC regardless of tumor grade without tumor-graded specimens showed an inversely statistically significant difference between the Ki-67 positive cells and INV expression (p<0.0001). In RT-PCR, mRNA expression of the FFPE specimens showed substantial similarity of INV expression as in IHC. It is suggested that the INV expression should be further studied in terms of clinical prognosis in canine cutaneous SCC.
