Abstract

Pellucide zone 3 (ZP3) involves in fertilization mechanism. Moreover, antibody of ZP3 can develop to inhibit egg and sperm interaction. This study aims to determine the effect of hZP3 (mab-hZP3) monoclonal antibody on the expression of Bcl-2 and Bax in follicle granulosa cells of the mice ovary. Female mice BALB/c were divided into 12 groups which consisted of control and experimental treatment group. Each group was added with 30% of total mice as error sample (1 mice). Each groups were treated differently: 50 µl adjuvant Al(OH)3 in 50 µl Tris HCl, 20 µg Mab-hZP3, 40 µg Mab- hZP3, and 60 µg Mab-hZP3. Each group was dissected at day 10, 15 and 20. Measurement of Bcl-2 and Bax was performed with immunohistochemistry. Data was analyzed by Two-Way ANOVA. There was no significant effect of Mab-hZP3 administration in various doses on Bcl-2 (p=0.0825), and Bax (p=0.836). There was no significant effect of administration of Mab-hZP3 in time (p=0.807), neither on Bcl-2 expression (p=0.088) and Bax (p=0.227). The lowest Bcl-2 level was found in dose of 60 µg in day 15. There was no significant effect of Mab-hZP3 in various doses and time (p=0.691), neither to Bcl-2 and Bax. Such results obtained due to the specificity of a monoclonal antibody that recognizes specific antigen. Mab-hZP3 is proposed as immunocontraception for women causing no disturbance of folliculogenesis.

Abstract

Cervical cancer recurs in 90% cases and linked to cancer stem cells that able to self-renew and responsible for recurrence, metastasis, and mortality of cancer. Isolation and identification of cancer stem cells using serum-free medium needs expensive growth factors and consume time. This study try to grow tumor sphere using culture plate coated with 1% agarose as an efficient and economical alternative to non-adhesive culture plate. HeLa cell line was grew in culture plate coated with 1% agarose and non-adhesive culture plate using similar medium and culture condition. Tumor spheres morphology was observed and the colonies were counted in 7 days followed by single cell assay. Tumor spheres then counted for CD133+, CD34+, and Sox2 expression using flowcytometry. Culture plate coated with 1% agarose can be used as an economic and efficient alternative to culture tumor sphere. Using culture plate coated with 1% agarose, the tumor spheres formed in 7 days with similar morphology to non-adhesive culture plate. Tumorsphere had three dimensional – sphere shape that tightly attached, colonized, and overlapped. The tumor sphere colony counts of two plates were statistically have no significant difference (p=0,667). Single cell assay of a tumor sphere shows that it can grow new tumor spheres with similar morphology. The tumor sphere from culture plate coated with 1% agarose express CD133+ and CD34+ as much as 8.78% ± 2.14 and Sox2 as much as 35.30% ± 23.82 whereas tumor sphere from non-adhesive culture plate express CD133+ and CD34+ as much as 62.36% ± 1.06 and Sox2 as much as 98.86% ± 0.56 (p = 0000).
