Application of Omics Technology in Diagnosis of the Canine Cancers
2019
Zamani-Ahmadmahmudi, Mohamad | azizi, Shahrzad
Nowadays, with the development of new technologies, improved and progressed methods have been taken to diagnose, treat and prevent cancers. Pathologic study and some molecular methods have been helpful in diagnosing and predicting cancer but these methods are not enough in many cases. Omics technology investigates many parts of cells such as genes, proteins, transcripts, and metabolites simultaneously. This procedure provides a more real and general feature of cellular processes, especially in cancer cells. In human, Omics technology is widely used to diagnose and treat various cancers and predict prognosis of tumors and survival of patients. In parallel to the studies of cancers in human, similar investigations were conducted in the canine cancers. Regarding the importance of Omics method in oncology, we described various Omics techniques including genomics, transcriptomics, and proteoimcs. In addition, corresponding studies carried out in different canine cancers were summarized in the next step.

BACKGROUND: Doxorubicin is one of the most widely used anticancer chemotherapeutic agents in small animal practice. The use of doxorubicin can cause cardiotoxicity, hepatotoxicity, neurotoxicity, and nephrotoxicity. OBJECTIVES: This study was carried out to evaluate the effects of ascorbic acid on doxorubicin hepatotoxicity in mice. METHODS: Twenty-four Balb/c mice were randomly divided into four groups. Group one received normal saline, group two received 100 mg/kg ascorbic acid, group three received 8 mg/kg doxorubicin and group four received ascorbic acid and doxorubicin intraperitoneally, with the same doses of groups 2 and 3. Twenty-one days after injection, the mice were euthanized. The activities of ALP, ALT, AST enzymes and total bilirubin levels in the serum samples were measured. Liver samples were evaluated histopathologically. RESULTS: The activities of ALP, ALT, AST, and total bilirubin levels and histopathologic scores of hepatotoxicity were significantly lower in the group that received ascorbic acid + doxorubicin in comparison to those of the doxorubicin group. CONCLUSIONS: Ascorbic acid may be useful in the prevention of doxorubicin hepatotoxicity in mice. Further studies are recommended for evaluation of the use of ascorbic acid in small animals.

Appendicular osteosarcoma (OSA) is a highly aggressive and metastatic primary bone tumour in dogs. Standard therapy is amputation and adjuvant chemotherapy (e.g. with doxorubicin). Liposomal drug delivery may augment therapeutic efficacy and reduce negative side effects. Polyethylene glycol (PEG)-liposomal doxorubicin treats human metastatic cancers effectively. The study aimed was to evaluate PEG-liposomal doxorubicin’s inhibitory effect on canine metastatic proliferation and migration in vitro. It also aimed to appraise the drug’s extravasation inhibition in vivo using the human medicine–proven chick embryo chorioallantoic membrane ex ovo model.

Phytoestrogens are non-steroid polyphenolic materials present in 300 plants. Regarding their structural similarities to estradiol, phytoestrogens attach to estrogen receptors and display anti-or pro-estrogenic activities. This review explored phytoestrogens' potential advantages and autophagy properties in light of their future application for disease management, highlighting how phytoestrogens could modulate autophagy. Research has examined the prospective benefits of phytoestrogens for the anticipation and management of various conditions, including signs of menopause, tumors, skin deterioration, osteoporosis, heart disease, neurodegenerative conditions, disorders of the immune system, and metabolic syndrome, owing to their therapeutic effects. As phytoestrogens can activate or inhibit autophagy, which has antioxidant, apoptotic, anti-mutagenic, anticancer, transcriptional, and genomic impacts on cancer and aging illnesses, phytoestrogens could influence diseases through the modulation of autophagy. The collaborative research on animal models, utilization of genetic techniques, and administration of pharmacolog¬ically active substances has indicated the possible therapeutic benefits of autophagy modulation in various illnesses. Further research is required to illustrate the pathways by which phytoestro¬gens modulate autophagy and the possible therapeutic effects on these diseases.
