Abstract

Carcinogenesis may resulted from the malfunctioning of programmed cell death. Most of the anticancer drugs incurrent use induce apoptosis in susceptible cells. The fact that disparate agent interacting with different targets seemto induce cell death through some common mechanisms suggest that anticancer activity is determined by the abilityof inhibiting cell growth. Pentagamavunon-1 (PGV-1) is one of the curcumin analogues which showed to havepotency in inhibiting proliferation of T47D human breast carcinoma cells. The effects on T47D cells growth isassociated with cell cycle arrest in G2/M phase at the concentration of 2.5 ?M, followed by hyperploidy. The data onpolymerization assay, indicated that PGV-1 interact with tubulin in different manner from taxol. PGV-1 inhibittubulin polymerization on cell culture while taxol stabilized tubulin polymerization. Immunostainning data onPGV-1 treated cells showed slightly tubulin condensation, while taxol treated cells showed tubulin condensationdistinctly at 12 minutes after releasing from depolymerizing agent.In conclusion, PGV-1 represent a new microtubule inhibitor and has the potential to be developed for antimitoticdrugKey words: Pentagamavunon-1, T47D, tubulin

Abstract

ABSTRACT Diabetets mellitus is a common desease which is caused by insulin secretion and action disorder. Prevelence of the desease was predicted to be increase 2,5 times in 2030, therefore, special treatment were needed to improve the quality of life diabetic patient. Recently, many natural drug has been developed for diabetic therapy. The objective of this research was to investigate the effect of boiled sponge gourd in reducing blood glucose dan lipid profile on male diabetic rats alloxan induced. Eighteen diabetic male wistar rats were divided into three groups, first grup were normal rats, second gorup were diabetic rats,and third gorup were diabetic rats that were treated with boiled sponge gourd for fourtheen days. The research showed that boiled sponge gourd was able to reduce blood glucose, total cholesterol and triglyceride. Keywords : Diabetes mellitus, gambas, anti diabetic drug, alloxan
