The insulin secretion expressed in terms of plasma concentration in response to an oral glucose load (1.8g per kg body weight) in biotin-deficient male Wistar rats was approximately one-sixth that of pair-fed controls. However, the insulin content of the pancreas in biotin-deficient rats was no lower than that of control rats. The reduction in insulin secretion in the biotin-deficient rats was reversed to a significant extent by the simultaneous administration of biotin (1mg per kg body weight) with the glucose solution. This suggests that biotin may play an important role in the secretion of insulin from the β-cells of the pancreas.

Alanine aminotransferase (ALT), aspartate transaminase (AST), and glutamyl transpeptidase (GGT) were three key enzymes in the hepatic metabolism. This study aimed to investigate the effect of homocysteine (Hcy) metabolism gene polymorphisms and serum Hcy and folate level on the hepatic functions in a Chinese hypertensive population. A representative sample with 480 subjects aged 28-75 was enrolled in 2005.9-2005.12 from six hospitals in different Chinese regions. Serum ALT, AST and GGT were measured by using an automatic biochemistry analyzer. Serum Hcy was measured by high-performance liquid chromatography, and serum folate was measured by chemiluminescent immunoassay. Known genotypes were detected by PCR-RFLP methods. The results showed that the MTHFR C677T mutation was related a decreased serum AST level (r=−0.11, p=0.026), whereas the MTHFR A1298C mutation elevated serum AST level (r=0.11, p=0.032). Furthermore, multiple regression analysis showed that folate deficiency was associated with higher serum ALT (β (SE): 0.13 (0.06), p=0.031) and GGT level (β (SE): 0.18 (0.07), p=0.011). However, serum Hcy level may not affect the hepatic functions. Our data suggested that hepatic functions were affected by MTHFR gene polymorphisms and serum folate level. Further studies are needed to confirm these correlations in a larger population.

CHIP (Carboxy terminus of Hsc70 Interacting Protein) is an E3 ubiquitin ligase that can induce ubiquitination and degradation of several oncogenic proteins. The expression of CHIP is frequently lower in human breast cancer than in normal breast tissue. However, the expression and role of CHIP in the canine mammary gland tumor (CMGT) remain unclear. We investigated the potential correlation between CHIP expression and mammary gland tumor prognosis in female dogs. CHIP expression was measured in 54 dogs by immunohistochemistry and real-time RT-PCR. CHIP protein expression was significantly correlated with the histopathological diagnosis, outcome of disease, and tumor classification. The transcriptional level of CHIP was significantly higher in normal tissues (P=0.001) and benign tumors (P=0.009) than it in malignant tumors. CHIP protein expression was significantly correlated with the transcriptional level of CHIP (P=0.0102). The log-rank test survival curves indicated that patients with low expression of CHIP had shorter overall periods of survival than those with higher CHIP protein expression (P=0.050). Our data suggest that CHIP may play an important role in the formation and development of CMGTs and serve as a valuable prognostic marker and potential target for genetic therapy.

Reports of dogs with H3N2 canine influenza virus (CIV) have been documented frequently. To better understand the seroprevalence of H3N2 CIV among dogs in northeast China, here we report for the first time a relatively high seroprevalence of H3N2 CIV infection in dogs in northeast China. Forty-five of the 223 canine sera (20.2%) and 166 of the 500 canine sera (33.2%) tested feral dogs and pet dogs were seropositive by NP-ELISA, which is higher than that in southern China. The relative data provided in this report can be useful for small animal practitioners or public health policy makers to carry out relative measures for the prevention of this disease. Meanwhile similar seroprevalence studies and prospective natural history and incidence studies should also be undertaken in other places.
