DECORIN EFFECTS ON PROTEOMIC PROFILING OF BREAST CANCER CELLS: AN UPDATED STUDY

2015

The malignant carcinomas are characterized by several capabilities acquired by the neoplastic cells, among which the ability to invade the extracellular matrix (ECM) and to establish a crosstalk with several ECM components. Under this respect, the extracellular microenvironment is an entity extraordinarily rich of information with opposite signals. Our group has long undertaken the study of the effects of ECM molecules on the behavior of cancer cells in vitro. Among the studied molecules, the decorin was found to exert a non-permissive effect on the growth and motility of the transfected tumor cells. The decorin, belongs to the family of small leucine-rich proteoglycans (SLRP) and is involv…

Synthesis of the New Ring System Bispyrido[4',3':4,5]pyrrolo [1,2-a:1',2'-d]pyrazine and Its Deaza Analogue

2014

Derivatives of the new ring systems bispyrido[4',3':4,5]pyrrolo[1,2-a:1',2'-d] pyrazine-6,13-dione and its deaza analogue pyrido[4'',3'':4',5']pyrrolo-[1',2':4,5]pyrazino [1,2-a]indole-6,13-dione were conveniently synthesized through a four-step sequence. Symmetrical derivatives of the former ring system were obtained through self condensation. On the other hand, condensation of 6-azaindole carboxylic acid with indole 2-carboxylic acid afforded the deaza analogue ring system. Derivatives of the title ring system were tested by the National Cancer Institute (Bethesda, MD, USA) and four of them exhibited modest activity against MCF7 (a breast cancer cell line) and/or UO-31 (a renal cancer cel…

Pure anti-oestrogens

2000

Pure anti-oestrogens are a group of at least five new compounds which are able to antagonize the effects of oestrogen in all tissues and species studied. The mechanism by which the pure anti-oestrogens produce their effects remains in question, but all of them are competitive antagonists of the oestrogen receptors and, moreover, have been proposed to block the shuttling of oestrogen receptors into the cell nucleus. When studied in vitro, these compounds are able to block the oestrogen-stimulated growth of breast cancer cells. In animals, their ability to block the effects of oestrogen on breast, uterus, bone, cardiovascular system and other reproductive-associated tissues has been demonstra…

The synergistic effect exerted by the HDAC inhibitor SAHA and the sesquiterpene lactone parthenolide on triple negative breast canc er cells

2014

Triple-negative breast cancer (TNBC) is a subtype o f breast cancer, insensitive to endocrine therapy. Chemotherapy is the main form of treatment, but is accompanied by a high rate of recidivism. The sesquiterpene lactone Parthenolide (PN) exerts a cy totoxic effect on MDA-MB231 cells, a TNBC cell line (1), but was ineffective at low doses (2-5μM). This repr esents an obstacle for a therapeutic utilization of PN. We supposed, in line with other authors (2), that PN c auses a protective response, which at low doses pre vails on the cytotoxic effect. With the aim of inhibiting this protective effect we have shown that pre-trea tment of MDA-MB231 cells with SAHA (2-5μM), an histone deace tylat…
