Abstract

Background: Breast cancer (BC) is the leading cause of death cancer in women. Cancer therapies using TNFα and IFNγ have been recently developed by direct effects and activation of immune responses. This study was performed to evaluate the effects of TNFα and IFNγ directly, and TNFα and IFNγ secreted by Conditioned Medium-human Wharton’s Jelly Mesenchymal Stem Cells (CM-hWJMSCs) toward apoptosis of BC cells (MCF7).Materials and Methods: BC cells were induced by TNFα and IFNγ in 175 and 350ng/mL, respectively. CM-hWJMSCs were produced by co-culture hWJMSCs and NK cells that secreted TNFα, IFNγ, perforin (Prf1), granzyme B (GzmB) for treating BC cells. The BC cells were treated with CM-hWJMSCs in 50%. The expression of apoptotic genes Bax, p53, and the antiapoptotic gene Bcl-2 were determined using RT-PCR.Results: TNFα and IFNγ at concentration of 350 ng/mL induced higher Bax expression compared to 175 ng/mL. TNFα and IFNγ 350 ng/mL, 175 ng/mL induced p53 expression, whilst TNFα and IFNγ at 350 ng/mL decreased Bcl-2 expression. Perf1, GzmB, TNFα and IFNγ-containing CM-hWJMSCs induced significantly apoptosis percentage, induced Bax expression, but did not effect p53, Bcl-2 expression.Conclusion: TNFα and IFNγ directly induce Bax, p53, decrease Bcl-2 gene expression. The Prf1, GzmB, TNFα, IFNγ-containing CM-hWJMSCs induce apoptosis and Bax expression.Keywords: breast cancer, Wharton’s Jelly mesenchymal stem cells, TNFα, IFNγ

Abstract

Zona pellucida is one of the protective layer of the egg cell and has a function as an intermediary species-specific fertilization. Glycoproteins of human and bovine zona pellucida is composed of three types, namely ZP1, ZP2 and ZP3. ZP3 gene has amino acid sequence homology with other mammals. Oligosaccharides components of the zona pellucida glycans are composed from units of asparagine residues (N -linked) and serine/threonine (O -linked). The aims of this study was to analyze the DNA sequences of human and bovine and further predicts glycans site on amino acid sequence of human and bovine ZP3. In this study, ZP3 gene fragments have been isolated from bovine and humans were analyzed in Silico. This work were conducted by comparing the data of DNA sequence from human and bovine PCR product using NCBI BLAST. The results showed that there were similarities at amino acid positions number 23-38. bZP3 sequence had three glycans site (Asn-X-Thr/Ser) and one site on hZP3 glycans. One of the sites was conserved between the two species.

Abstract

The purpose of the study was to determine the influence of the concentration of ethylene glycol (EG) and length of exposure to levels of bovine oocytes in vitro fertility. This research was conducted using a completely randomized design factorial 5x3 with 7 replicates. The first factor was the concentration of cryoprotectants EG 10, 20, 30, 40, and 50%. The second factor was the length of exposure 1, 3, and 5 minutes. The results showed that the concentration of EG and the length of exposure were effect on fertilized oocytes (P0.05). The level of oocytes in vitro fertility after vitrification in 30% EG and long exposure to 3 minutes did not different (P0.05) compared to fresh oocytes, while the EG treatment 10, 20, 40, and 50% significantly showed a lower fertility rate than the 30% EG (P0.05). It was concluded that the concentration of EG and length of exposure were effect on fertilized oocytes. The highest oocytes in vitro fertility level were found in 30% EG concentration with 3 minutes exposure time.

Abstract

Tujuan penelitian ini untuk mengetahui pengaruh induksi EGF terhadap lokalisasi Cx43 dan gap junction selama ekspansi sel kumulus. Hasil penelitian ini menunjukkan bahwa ekspansi sel kumulus mempunyai signifikansi dengan meningkatnya konsentrasi EGF dan waktu kultur. Ekspansi sel kumulus diindikasikan dengan perubahan bentuk sel menjadi memanjang dan menyebar. Ekspresi Cx43 meningkat pada kultur jam ke-5 dan semakin meningkat pada kultur jam ke-10 dengan semakin padatnya protein pada badan sel. Pada kultur jam ke-15 terjadi penurunan ekspresi Cx43 pada badan sel. EGF berpengaruh terhadap peningkatan ekspansi sel kumulus tetapi tidak pada ekspresi Cx43 dengan bertambahnya konsentrasi dan waktu kultur. Hal ini menunjukkan bahwa komunikasi antar sel kumulus menurun, karena jarak antar sel yang semakin jauh.
