It is shown that daily oral administration of 5--10 mg of an antidiabetic biguanide-phenformin (phenethyl-biguanide) for 2.5--5 months suppressed DMBA-induced mammary tumour development in rats considerably. Phenformin-treated rats revealed-a tendency towards a decrease in blood insulin level (radioimmunoassay). The obtained data are regarded as additional evidence for the proposed existence of the same metabolic background of diseases of compensation, i.e. adult-onset diabetes, artherosclerosis and cancer, and suggest studies on possible antitumour effect of phenformin in man.

UI MeSH Term Description Entries
D007328 Insulin A 51-amino acid pancreatic hormone that plays a major role in the regulation of glucose metabolism, directly by suppressing endogenous glucose production (GLYCOGENOLYSIS; GLUCONEOGENESIS) and indirectly by suppressing GLUCAGON secretion and LIPOLYSIS. Native insulin is a globular protein comprised of a zinc-coordinated hexamer. Each insulin monomer containing two chains, A (21 residues) and B (30 residues), linked by two disulfide bonds. Insulin is used as a drug to control insulin-dependent diabetes mellitus (DIABETES MELLITUS, TYPE 1).

D010629 Phenformin A biguanide hypoglycemic agent with actions and uses similar to those of METFORMIN. Although it is generally considered to be associated with an unacceptably high incidence of lactic acidosis, often fatal, it is still available in some countries.
