<p align="justify">Indonesia is an agricultural country that most of their society works as farmer. One of commodity in Indonesia is tea plantation which is located in Malang (Brawijaya University takes place). Malang is resited at 440-667 (mdpl) altitude, one of the tourist destinations in East Java because of the potential of natural and climatic owned. Malang climate conditions during 2008 temperatures recorded ranging from 22.7 ° C to 25.1 ° C. While the maximum temperature reached 32.7 ° C and minimum temperature of 18.4 ° C. The average air humidity range 79% - 86%. With a maximum moisture content of 99% and a minimum at 40%. These conditions favor the development of the tea plant (Camellia sinensis). <br>

Tea extract contain EGCG used as the most effective antioxidant to against cervical cancer. But, levels of EGCG (Epigallocathecin gallate) in tea is very slightly. So, we will increase the level of this EGCG compound using siRNA to knockdown gene non-EGCG with expectation it will produce high yield of antioxidant. The applications are for supplement or feminine hygiene.<br><br>

Epigallocatechin-3-gallate (EGCG) is a polyphenol constituent present in green tea to inhibit cancer growth and the effects of EGCG is a potential anti-proliferative and pro-apoptotic agent in the human ovarian cancer line.But, levels of EGCG (Epigallocathecin gallate) in tea is very slightly.

<p align="justify">Tea plant (Camelia sinensis) has catechin compounds that contains antioxidants.  Catechin family that most effective used as antioxidant is Epigallocathecin gallate (EGCG).  Based on research in vitro and in silico, EGCG is able to inhibit the proliferation of cancer cells with stop over-expression between L1 HPV 16- EGFR (Epithel Growth Factor Receptor) bond but there are few of EGCG content in tea plant.

EGCG is able to inhibit the proliferation of cancer cells (Cornelia, 2013) because stop over-expression between L1 HPV 16- EGFR (Epithel Growth Factor Receptor) bond but there are few of EGCG content in tea plant. Based on these problems, we would to over- expression EGCG by knockdown non-compound EGCG gene, so hopefully the content of EGCG on tea are more prominent.<br><br>

We design siRNA sequence from LAR gene (to inhibit non-EGCG compound) using bioinformatics tool to initiate expression in mammalian cell (using HeLa cell). That part will be insert into the pSB1C3 linear backbone. To checking performance of this part, should be react with sequence target of siRNA LAR into the plasmid pSB1C3. We also prepare for positive control containing siRNA for GFP, insert into pSB1C3. Each part will be growth in HeLa cell culture and observed the succeding by fluorescent microscope.<br><br>

Based on these problems, we would to over- expression EGCG by knockdown non-compound EGCG gene, so hopefully the content of EGCG on tea are more prominent.  We design siRNA sequence from LAR gene (to inhibit non-EGCG compound) using bioinformatics tool and use P97 promoter to initiate expression in mammalian cell (using HeLa cell). That part will be insert into the psB1C3 linear backbone. To checking performance of this part, we insert sequence target of siRNA into the plasmid Bba_E0240 and get the promoter CMV from Bba_K747096 part. We also prepare for positive control and negative control for this experiment. Positive control part containing siRNA for GFP, insert into Bba_K747096 part that contain CMV promoter, and negative control containing CMV promoter and insert to the Bba_E0240 part containing GFP. Each part will be growth in HeLa cell culture and observed the succeding by fluorescent microscope.
