Research topic 15: Biomolecules, Nutritional Regimen and Drugs Retask to Treat Diabesity Epidemic
Because of the rapidly escalating prevalence of diabesity (coexistence of both diabetes, mostly type 2 and obesity), there is an urgent need for new preventive and therapeutic approaches to treat this disease. Therefore, diabesity is a modern epidemic, linked by various pathophysiological mechanisms, revolving around insulin resistance and hyperinsulinemia, diabesity has important diagnostic and therapeutic implications. In this view, we study insulin secretion mechanism and using transcriptomic approaches we identify molecular signature by comparisons (estimating similarity) of biomolecules, nutritional regimen, and drug re-task- disease. The transcriptomic approach is performed on biological material, such as cells or tissue, before and after treatment. The difference of gene expression is then compared with a disease-associated expression profile that has been similarly obtained through differential expression analysis of disease versus healthy conditions.   
Keywords: Diabesity, Insulin secretion, Transcriptomic, Drug retask.

Research topic 16: Dissecting novel mechanisms fine tuning breast cancer progression toward drug discovery and more comprehensive therapeutic approaches.
Estrogens, growth factors and G protein-coupled receptors activate an intricate signalling network leading to a gene signature involved in the acquisition of aggressive features and therapy resistance in endocrine-related tumors, including breast cancer. Therefore, the research activity aims to dissect novel mechanisms triggering this complex scenario toward the identification of therapeutics that would be critical in more comprehensive clinical settings.
Keywords: Estrogens, Growth Factors, G protein-coupled receptors, Drug discovery, Precision medicine, Breast cancer.
Research Topic 17: Effect of valproic acid in ER?-positive and negative breast cancer cells
Valproic acid (VPA), a member of HDAC inhibitors, used as antiepileptic drug, raised interest for its antitumor activity. Our recent data, demonstrated that in LNCaP prostate tumor cells, VPA reduces proliferation, and drives neuroendocrine phenotype. We are now studying the VPA role in breast cancer cells. Our data evidenced a decrease of proliferation and cell cycle arrest. The molecular mechanisms involved in apoptosis and inflammation in VPA-treated breast cancer cells will be investigated.
Keywords: Valproic acid, Breast cancer, Proliferation, Cell cycle, Apoptosis, Inflammation.
Research topic 18: Obesity and Breast Cancer: Unraveling the Role of Adipose Tissue in Breast Cancer Growth and Progression
Obesity has an intricate connection to both risk and clinical behaviour of breast cancers providing a unique adipose tissue microenvironment that, along with systemic modifications, promotes breast carcinogenesis. Unraveling the role of the adipokine leptin and the adipocyte-derived exosomes, as well-established mediators of intercellular communication, may open a new molecular window on the connection between obesity and breast cancer and identify novel biomarkers and/or therapeutic targets.
Keywords: Obesity, Adipose tissue, Breast cancer, Tumor microenvironment, Leptin, Exosomes.
Research topic 19: PPARgamma in the breast tumor microenvironment: novel therapeutic strategies for breast cancer treatment
The tumour microenvironment plays a key role in breast cancer progression. PPARγ, a nuclear receptor involved in adipocyte differentiation and glucose metabolism, also functions as a tumor suppressor. Activation of PPARγ by natural or synthetic ligands, including omega-3-PUFAs or TZDs, exerts inhibitory effects on breast cancer growth. Unraveling the role of activated PPARγ in tumor microenvironment could be paramount for a rational design of new therapy schemes for breast cancer patients.
Keywords: Nuclear receptors, Peroxisome proliferator-activated receptor gamma, Breast cancer, Tumor microenvironment thiazolidinediones (TZDs), Omega-3 polyunsaturated fatty acids (PUFAs).
Research topic 20: Identification of diagnostic and prognostic gene-based biomarkers in neurodegenerative disorders and oncology
Both neurodegenerative disorders, including Amyotrophic Lateral Sclerosis, and cancer are characterized by a multifactorial etiology, meaning that the onset, progression and therapeutic response depend on a complex interaction among multiple genes, environmental factors, epigenetics and individual lifestyle. In this context, the identification of specific gene-based biomarkers appears to be extremely helpful to identify at-risk individuals, perform early diagnosis, select the most suitable therapy and counteract the progression and mortality of such public health issues.
Keywords: Multifactorial diseases, Mutations, Susceptibility genes.
Research topic 21: FoxO3a as a Prognostic Marker and a Therapeutic Target in Breast Cancer
In the past two decades, Prof. Sisci has focused his research interest on the cross-talk existing between growth factors (GF) and steroid hormones in breast cancer. Particular emphasis has been lately given to the transcription factor Forkhead Box 3a (FoxO3a), a downstream effector of the PI3K/AKT pathway, and to its potential role as a novel marker of good prognosis in estrogen receptor α (ERα) breast tumors. FoxO3a deregulation in tamoxifen resistant phenotypes is being investigated as well.
Keywords: Breast cancer; FoxO3a; Tumor suppressor; Growth factors signaling; Estrogen receptor; Tamoxifen resistance.
