The dichloromethanolic fraction of keladi tikus (Typhonium flagelliforme) extract and the expression of p21 and caspase-3 of MCF-7 breast cancer cell-line Background: Breast cancer has a high degree of heterogeneity and problems in therapy, such as insensitive to antiproliferation signal and able to escape from apoptosis program. Typhonium flagelliforme (Lodd), Blume (Araceae) more commonly known as keladi tikus in Indonesia, often used as alternative in treating cancer, including breast cancer. The objective of study is proving the dichloromethanolic fraction of Typhonium flagelliforme tuber extracts influence on the expression of caspase-3 and p21 of MCF-7 cell-line that have deletion in CASP-3 gene. Methods: This study adapts laboratory experimental in-vitro in cells-line MCF-7, with “post test control group only design” and divided into two groups, were incubated in 5h, 10h and 20h. The control group received no other treatment. The treatment group received the dichloromethanolic fraction of Typhonium flagelliforme tuber extracts in IC50. Starting with cytotoxicity assay using MTT to determine the IC50, followed by Immunocytochemical analysis to observe the expression of p21 and caspase-3. Results: Paired sample T test shows a significant differences in treatment groups compared with the controls (p<0.05), namely an increase in the expression of nuclear p21 and caspase-3 on 20h incubation. Conclusion: There were increased in the expression of caspase-3 and nuclear p21, as well as depleted the cytoplasmic of p21 on MCF-7 cell-line that have deletion in CASP-3 in treatment by tuber extract of Typhonium flagelliforme dichloromethanolic fraction.
