We have isolated 14 differentially displayed and 10 further expressed sequence tags (ESTs) from Musculus biceps femoris of newborn healthy and splay leg piglets. By comparison with EMBL/GenBank data we could identify nine porcine homologues to human genes (TATA box binding protein associated factor B TAF1B; B-cell CLL/lymphoma 7B BCL7B; pyruvate dehydrogenase kinase, isoenzyme 4 PDK4; ribosomal protein S10 RPS10; SPARC-like 1 SPARCL1; epithelial protein lost in neoplasm beta EPLIN; N-myc downstream-regulated gene 2 NDRG2; pleiomorphic adenoma gene like 2 PLAGL and, BCL-2 associated transcription factor short form BTFS). Eight fragments correspond to uncharacterized ESTs and 7 ESTs had no significant match with database sequences. These data provide the first expression profiles in skeletal muscle of neonatal piglets and are a basis for candidate gene investigations for congenital splay leg in piglets. Eleven ESTs were physically mapped to porcine chromosomes 1, 3, 4, 5, 7, 8, 9 and 10 and contribute to the comparative map of humans and pigs.

Colorectal carcinoma is among the most common malignancies. The tumour cells may arise from mutations in genes encoding proteins involved in the regulation of cell survival and proliferation. Recent evidence disclosed the sensitivity of colon carcinoma to the expression of ubiquitous serum and glucocorticoid inducible kinase-1 (SGK1). The kinase is activated by insulin and growth factors via the phosphatidylinositide-3-kinase (PI3K) and the 3-phosphoinositide dependent kinase (PDK1). SGK1 regulates channels, carriers and Na(+)/K(+)-ATPase, enzymes such as glycogen-synthase-kinase-3 (GSK3) and ubiquitin-ligase Nedd4-2, as well as several transcription factors. SGK1 regulates transport, hormone release, neuroexcitability, inflammation, cell proliferation and apoptosis. SGK1 contributes to metabolic syndrome and the pathophysiology of neurodegeneration, allergy, peptic ulcer, fibrosing disease and response to ischemia. SGK1 is upregulated in some tumours but downregulated in others. SGK1-sensitive mechanisms fostering tumour growth include activation of K(+) channels and Ca(2+) channels, Na(+)/H(+) exchanger, amino acid transporters and glucose transporters, upregulation of the nuclear factor NFkappaB and beta-catenin as well as downregulation of the transcription factors Foxo3a/FKHRL1 and p53. SGK1 enhances survival, invasiveness, motility, epithelial to mesenchymal transition and adhesiveness of tumour cells. Following deficiency of APC (adenoma polyposis coli) or chemical cancerogenesis, SGK1 knockout mice develop less intestinal tumours than their wild-type littermates and pharmacological SGK1 inhibition counteracts growth of prostate cancer cells.

Targeting mitochondrial energy metabolism is a novel approach in cancer research and can be traced back to the description of the Warburg effect. Dichloroacetate, a controversially discussed subject of many studies in cancer research, is a pyruvate dehydrogenase kinase inhibitor. Dichloroacetate causes metabolic changes in cancerous glycolysis towards oxidative phosphorylation via indirect activation of pyruvate dehydrogenase in mitochondria. Canine mammary cancer is frequently diagnosed but after therapy prognosis still remains poor. In this study, canine mammary carcinoma, adenoma and non-neoplastic mammary gland cell lines were treated using 10 mM Dichloroacetate. The effect on cell number, lactate release and PDH expression and cell respiration was investigated. Further, the effect on apoptosis and several apoptotic proteins, proliferation, and microRNA expression was evaluated. Dichloroacetate was found to reduce cell proliferation without inducing apoptosis in all examined cell lines.
