The Activity of Hydrolyzed Virgin Coconut Oil to Increase Proliferation and Cyclooxygenase-2 Expression towards on...

This study aims to determine the effect of hydrolysed virgin coconut oil (HVCO) to increase cell proliferation, COX-2 expression of NIH 3T3.

The sample used was Virgin Coconut Oil (VCO). VCO was partially hydrolysed using lipase from Rhizomucor miehei (active on sn-1,3 position) to produce hydrolysed VCO (HVCO) composed of free fatty acids, 2-monoglycerides. Then acid value was determined. The effect of HVCO on proliferation was evaluated using the MTT method. Wound healing assay was established by a cell migration method, and COX-2 expression was determined using RT-PCR.

Acid value is 135.89 ± 0.12 mg NaOH/g oil and free fatty acids (FFA) is 48.50 ± 0.06%. The effect of HVCO 62.5 µg/mL on cell proliferation after 24h, 48h, and 72h incubation found as viable cells are 109.24 ± 0.52%; 118.26 ± 0.91% and 106.59 ± 0.74%. Percent of wound closed after 24 h and 48 h incubation are 69.94 ± 0.54% and 100.00 ± 0.00%, and expression of COX-2 increased from 1 (control) to 1.83 (HVCO).

The results suggest that HVCO is effective to increase cells proliferation and hence wound healing process.
