Abstract
Purpose: Organic extracts of plant Annonaceae enhances apoptosis in animal cells and get the drives to reach a new homeostasis. The incidence rate of nasopharyngeal cancer in Indonesia is quite high. Protein 53Kd (p53) play a role in apoptosis process, being heat shock protein 70 (hsp70) play a role in homeostasis. The aim of this research is to identify the apoptotic effects of Annona muricata Linn leaf toward Raji cells by observing the p53 and hsp70 expression. Methods : Apoptotic assay was performed in 24 wells micro-culture plate. Raji cells were prepared as 2 × 10 4 cells in 100 ml RPMI media per well. Roswell Park Memorial Institute (RPMI) medium was created and solvent was controlled with Dimethyl Sulfoxide (DMSO) solvent 0.25. Apoptotic test was performed by calculating trypan-blue-dye exclution. The cells were then grown in micro-culture plate with media plus extract non-lethal concentration of partition and fractionation of Annona muricata Linn leaf. The sampling was performed for 24 hours. The number of living cells was calculated in each of these well and incubation time were determined. Immunohistochemical staining was done to identify the expression of p53 and hsp70. Results: The results showed that Raji cells treated with partition of Annona muricata Linn leaf in ethyl acetate solvent 133.00 % resulted in higher apoptosis. Another results showed that Raji cells treated with fractionation Annona muricata Linn leaf in ethyl acetate solvent 103.20 % resulted in higher apoptosis. The expression of p53 after treatment with fractionation Annona muricata Linn leaf was higher than before while hsp70 expression after treatment with fractionation Annona muricata Linn leaf was lower. Conclusion : The conclusion is the higher the dose of Annona muricata Linn the higher the p53 expression thereby activates apoptosis process The higher dose of Anonna muricata Linn also leads to lower hsp70 expression indicating stable homeostasis of Raji cells. ---------------------------------------------- Cite this article as: Astirin OP, Prayitno A, Artanti AN, Fitria MS, Witianingsih DA, Pranatami DA, Putra ST.

Highlights
Drug substance from herbs interacted with virus in the development of cancer do not so by interacting by the agent but rather through a direct effect on cell transformed apoptosis and proliferation
Raji cells were prepare as 2 × 104cells in 100ml Roswell Park Memorial Institute (RPMI) Media
This was followed by the creation of RPMI control and solvent plus Dimethyl Sulfoxide (DMSO) 0.25 %
Summary
Drug substance from herbs interacted with virus in the development of cancer do not so by interacting by the agent but rather through a direct effect on cell transformed apoptosis and proliferation. Considering the high potential herbs in managing various disease, need to be researched the Annona muricata Linn, especially in kill nasopharyngeal cancer cells
