66430 - Veterinary General Pathology and Molecular Oncogenesis

Learning outcomes

The student knowscell and tissue pathologic processes, in particular molecular pathogenetic processesin regressive, difensive, neoplastic trasformation and in vascular disorders. The student is able torecognize a pathologic process.

Course contents

Veterinary General Pathology

Etiology, pathogenesis and morphology of atophy, necrosis, apoptosis andgangrene. Inflammation: changes in vascular flow and caliber, exudation and leukocyte extravasation, fluid and cellular components of inflammation, molecular basis of inflammation, acute and chronic inflammations. Anaemia: classification and pathogenesis. Radiation pathology. Hypersensitivity reaction I, II, III, and IV type

Molecular oncology

Biology of tumor growth: benign and malignant neoplasms (differentiation, anaplasia, rates of growth, cancer stem cells and cancer cell lineages, local invasion, metastasis). Molecular basis of cancer (essential alterations for malignant transformation, the normal cell cycle, self-sufficiency in growth signals, oncogenes, protooncogenes, oncoprotein, insensitivity to growth inhibitory signals, tumor suppressor genes, evasion of apoptosis, DNA repair defect and genomic instability in cancer cells, telomerase, development of sustained angiogenesis, invasion and metastasis, stromal microenvironment and carcinogenesis, dysregulation of cancer-associated genes). Molecular basis of multistep carcinogenesis. Carcinogenic agents and their cellular interaction (chemical carcinogenesis, radiation carcinogenesis, microbial carcinogenesis). Host defense against tumors, tumor immunity (tumor antigens, antitumor effector mechanisms, immune surveillance).Clinical characteristic of tumors. Effect of the tumour in the host. Tumoral grading and staging. Laboratory diagnosis of tumours
