Rhazya Stricta

Background: Rhazya stricta has been used as a folkloric medicinal herb for treating various diseases such as diabetes, inflammatory disorders, and sore throat. Several studies have revealed the potential of this plant as an important source of phytochemicals with anticancer properties. Objective: The present study was designed to isolate a novel anticancer compound from Rhazya stricta and elucidate its mechanism of action using genomics approach. Methods: Rhazya stricta leaves extract was prepared, and several alkaloids were purified and characterized. These alkaloids were screened for their anticancer potential. One of the alkaloids, termed as isopicrinine, showed efficient cytotoxicity against MCF7 breast cancer cell line and was selected for further analysis. RNA-Seq transcription profiling was conducted to identify the affected genes and cellular pathways in MCF7 cells after treatment with isopicrinine alkaloid. Results: In vitro studies revealed that newly identified isopicrinine alkaloid possess efficient anticancer activity. Exposure of MCF7 cells with isopicrinine affected the expression of various genes involved in p53 signaling pathway. One of the crucial proapoptotic genes, significantly upregulated in MCF7 after exposure to alkaloid, was PUMA (p53 upregulated modulator of apoptosis), which is involved in p53-dependent and -independent apoptosis. Moreover, exposure of sublethal dose of isopicrinine alkaloid in breast cancer cell line led to the downregulation of survivin, which is involved in negative regulation of apoptosis. Besides, several genes involved in mitosis and cell proliferation were significantly downregulated. Conclusion: In this article, we report the determination of a new alkaloid isopicrinine from the aerial parts of Rhazya stricta with anticancer property. This compound has the potential to be developed as a drug for curing cancer.

The present research work is designed to prepare and evaluate piperine liposomes and piperine–chitosan-coated liposomes for oral delivery. Piperine (PPN) is a water-insoluble bioactive compound used for different diseases. The prepared formulations were evaluated for physicochemical study, mucoadhesive study, permeation study and in vitro cytotoxic study using the MCF7 breast cancer cell line. Piperine-loaded liposomes (PLF) were prepared by the thin-film evaporation method. The selected liposomes were coated with chitosan (PLFC) by electrostatic deposition to enhance the mucoadhesive property and in vitro therapeutic efficacy. Based on the findings of the study, the prepared PPN liposomes (PLF3) and chitosan coated PPN liposomes (PLF3C1) showed a nanometric size range of 165.7 ± 7.4 to 243.4 ± 7.5, a narrow polydispersity index (>0.3) and zeta potential (−7.1 to 29.8 mV). The average encapsulation efficiency was found to be between 60 and 80% for all prepared formulations. The drug release and permeation study profile showed biphasic release behavior and enhanced PPN permeation. The in vitro antioxidant study results showed a comparable antioxidant activity with pure PPN. The anticancer study depicted that the cell viability assay of tested PLF3C2 has significantly (p < 0.001)) reduced the IC50 when compared with pure PPN. The study revealed that oral chitosan-coated liposomes are a promising delivery system for the PPN and can increase the therapeutic efficacy against the breast cancer cell line.

Kanker payudara yang paling banyak ditemukan adalah subtipe luminal A dengan karakteristik Estrogen Reseptor+. Subjek penelitian akan diwakili oleh cell line MCF-7 dan Umbilical Cord Blood Mesenchymal Stem Cell (UCBMSC). Over expression Myc pada kanker payudara mengakibatkan sel kanker menjadi lebih invasif dan terjadi resistensi terhadap terapi hormonal. Tujuan penelitian ini adalah mengidentifikasi ekspresi gen Myc pada cell line MCF-7 sebelum dan sesudah pemberian sel punca. Penelitian ini menggunakan desain experimental secara in vitro. Sampel menggunakan MCF-7 dan sel punca yang dibagi menjadi 4 kelompok, yaitu K1 (kelompok kontrol MCF-7), K2 (kelompok kontrol sel punca), P1 (perlakuan subkultur MCF-7 dengan sel punca inkubasi 24 jam), dan P2 (inkubasi 48 jam). Kemudian, dilakukan isolasi RNA, sintesis cDNA, dan ekspresi Myc diperiksa menggunakan PCR dan elektroforesis. Analisa data yang digunakan adalan One Way ANOVA dan post-hoc LSD. Hasil analisis bivariat didapatkan p<0,05. Dari uji post-hoc LSD tidak ditemukan perbedaan yang bermakna antara K1 dengan P1, K1 dengan P2, dan K2 dengan P2. Namun, tetap ditemukan perbedaan yang bermakna antara K2 dengan P1 dan P1 dengan P2. Simpulan penelitian ini adalah tidak terdapat perbedaan bermakna ekspresi gen Myc pada subkultur antara MCF-7 breast cancer cell line dengan pemberian sel punca mesenkimal.

Background: The lack of treatment options for patients with chemotherapy-resistant cancers is pushing the field toward the development of new therapies. 1,2,4,5-tetrazine derivatives are a class of heterocyclic compounds that exhibit a broad spectrum of antitumor activities. Objective: The purpose of this study was to assess the biological activity of four s-tetrazine derivatives by substitution of two chloride atom of 3,6-dichloro-1,2,4,5-tetrazine with long hydrophobic side chains. Methods: We analyzed the anti-proliferative effects of four s-tetrazine derivatives with MTT assay and their pro-apoptotic effect with AV/ IP flow cytometry analysis and Hoechst 33342 staining. Results: We demonstrated that 3,6-dichloro-1,2,4,5-tetrazine (compound (1)) has a cytotoxic effect and induces apoptosis. Conclusion: 3,6-dichloro-1,2,4,5-tetrazine presents a new cytotoxic drug against metastatic breast cancer cell line MDA-MB-231 in vitro.
