miR-486-5p regulates cell proliferation and migration in breast cancer

In this study, the miR-86-5p was induced in breast cancer cells (MDA-MB-231) and the effect of miR-86-5p replacement on the expression level of VEGF, FOX, MMP3, SIRT1, and OLFM4 genes was investigated.Material and methodsThe miR-86-5p mature sequence was designed, synthesized and transfected into the MDA-MB-231 cells via jetPRIME® transfection reagent. The optimal concentration of miRNA was determined using qRT-PCR post-transfection. MTT assay was performed to evaluate the cell toxicity of miR-86-5p replacement. For finding the role of miR-86-5p in apoptosis, the annexin V/Propidium iodid (PI) assay was performed by flow cytometry analysis. A wound-healing assay (scratch assay) was performed to assess the effect of miR-86-5p on cell migration. The qRT-PCR method was used for measuring the expression level of miR-86-5p, VEGF, FOX, SIRT1, MMP3, and OLFM4.ResultsThe results showed that the optimal concentration of miRNA was 7.5 nM. The result of MTT and apoptosis assays revealed that miR-86-5p decreased cell viability and induced apoptosis. The wound healing assays showed that the miR-86-5p inhibited cell migration. Our results also showed that the miR-86-5p reduced VEGF, MMP3, OLFM4, and SIRT1 expression compared to the negative control cells. Thus, the miR-486 may act as a tumor suppressor and plays a vital role in cell apoptosis, cell growth and migration during breast cancer development. Our results showed that miR-86-5p could be a promising candidate to be used as a t...

A novel 20(S)-Rh2 derivative, 2-Deoxy-Rh2 was synthesized and hybridized with protopanaxadiol and 2-deoxy-glucose in an attempt to enhance the anticancer activity. Through screening the antitumor effect against various cell lines by MTT assay, 2-Deoxy-Rh2 especially resulted in a concentration-dependent and ti...

Authors: Kang YJ, Lee HB, Kim YG, Han J, Kim Y, Yoo TK, Lee ES, Moon HG, Noh DY, Han W Abstract Objective: While the value of Ki-67 has been recognized in breast cancer, controversy also exists. The goal of this study is to show the prognostic value of Ki-67 according to progesterone receptor (PgR) expression in patients who have estrogen receptor- (ER-) positive, human epidermal growth factor receptor 2- (HER2-) negative early breast cancer. Methods: The records of nonmetastatic invasive breast cancer patients who underwent surgery at a single institution between 2009 and 2012 were reviewed. Primary end point ...

Authors: Geng W, Dong K, Pu Q, Lv Y, Gao H Abstract SHOC2 leucine rich repeat scaffold protein (SHOC2) has been identified as a positive regulator of the Ras pathway; however, the function of SHOC2 in breast cancer has rarely been explored. The current study investigated the effects of SHOC2 on breast cancer cell growth and evaluated its prognostic value in patients with breast cancer. The effects of SHOC2 on MCF‑7 and MDA‑MB‑231 breast cancer cells were studied using short hairpin RNA. In total, 120 pairs of formalin‑fixed, paraffin‑embedded breast cancer tissue specimens were compared to normal tis...

Mol Med Rep. 2020 Feb;21(2):557-566 Authors: Zhong G, Lou W, Shen Q, Yu K, Zheng Y Abstract Triple‑negative breast cancer (TNBC) accounts for the worst prognosis of all types of breast cancers due to a high risk of recurrence and a lack of targeted therapeutic options. Extensive effort is required to identify novel targets for TNBC. In the present study, a robust rank aggregation (RRA) analysis based on genome‑wide gene expression datasets involving TNBC patients from the Gen...

CONCLUSION: Mammography was more accurate than ultrasonography in measuring the largest cancer diameter in DCIS of breast cancer. The correlation coefficient improved in the group of almost entirely fatty/ scattered areas of fibroglandular dense breast or in microcalcification negative group.
