| Summary: | Cancer can be classified as a fourth leading cause of death in Malaysia. There is a continuous effort by scientists
in finding alternative cure to cancer due to the known side effects of chemotherapy and radiation therapy as well as
recurrences. One of the latest methods to kill cancerous cells is by using immune cells known as natural killer (NK) cells.
Flavonoids such as flavone and flavonol are also known for their antioxidant, anti-inflammatory, immunomodulatory
and anticancer properties. This study was carried out to determine the role of flavonoid compounds of apigenin, luteolin,
and quercetin to facilitate the growth of NK-92 cells. NK-92 cell line was grown in tissue culture flasks containing
α- Minimum Essential Medium (MEM) medium enriched with L-glutamine, 12.5% fetal bovine serum, 12.5% horse
serum, 0.2 mM myo-inositol, 0.02 mM folic acid, and 100 - 200 U/mL recombinant interleukin 2 (IL-2). The cell
viability was determined via trypan blue staining where the cells were manually counted by a haemocytometer. The
3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used to determine the cell viability of
NK-92 cells after treatment with apigenin, luteolin, and quercetin. Results showed a dose-dependent proliferative effects
of apigenin, luteolin, and quercetin on the proliferation of NK-92 cells showing the highest percentage of proliferation at
100 µg/mL for all compounds (*P < 0.05). However, exceeding the dose of 100 µg/mL had resulted in a decline of cell
proliferations percentage. Based on these findings, flavonoid compounds comprising apigenin, luteolin and quercetin
were able to induce proliferative effects on NK-92 cells. |
