Background. Despite recent advances in scientific knowledge and clinical practice, management, and treatment of breast cancer, as one of the leading causes of female mortality, breast cancer remains a major burden. Recently, methods employing stem cells and their derivatives, i.e., exosomes, in gene-based therapies hold great promise. Since these natural nanovesicles are able to transmit crucial cellular information which can be engineered to have robust delivery and targeting capacity, they are considered one of the modes of intercellular communication. miR-145, one of the downregulated microRNAs (miRNAs) in various cancers, can regulate tumor cell invasion, metastasis, apoptosis, and proliferation and stem cell differentiation. Objectives. The aim of this study was to investigate the role of exosomes secreted from adipose tissue-derived mesenchymal stem cells (MSCs) for miR-145 transfection into breast cancer cells in order to weaken their expansion and metastasis. Methods. Here, we exploited the exosomes from adipose tissue-derived mesenchymal stem cells (MSC-Exo) to deliver miR-145 in the T-47D breast cancer cell line. Lentiviral vectors of miR-145-pLenti-III-enhanced green fluorescent protein (eGFP) and empty pLenti-III-eGFP as the backbone were used to transfect MSCs and T-47D cells. In order to find the efficiency of exosomes as a delivery vehicle, the expression level of some miR-145 target genes, including Rho-Associated Coiled-Coil Containing Protein Kinase 1 (ROCK1), Erb-B2 Receptor Tyrosine Kinase 2 (ERBB2), Matrix Metalloproteinase 9 (MMP9), and Tumor Protein p53 (TP53), was compared in all treatment groups (T-47D cells treated by miR-145-transfected MSCs and their derivatives or their backbone) and control group (untransfected T-47D cells) using real-time PCR. Results. The obtained data represented the inhibitory effect of miR-145 on apoptosis induction and metastasis in both direct miR-treated groups. However, exosome-mediated delivery caused an improved anticancer property of miR-145. Conclusion. Restoration of miR-145 using MSC-Exo can be considered a potential novel therapeutic strategy in breast cancer in the future.

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.
