General description
Sigma′s Mission Lenti-miRs express miRNAs from a common backbone, whose structure meets requirements for accurate Dicer processing and a partially complementary strand is designed to mimic the base pairing pattern in the backbone structure using a proprietary algorithm. Oligos containing the microRNA sequences are cloned into the TRC2-pLKO-puro vector. Each miRNA construct has been cloned and sequence verified. Mature microRNA sequences are obtained from miRBase.
Lentiviral transduction particles are produced from sequence-verified lentiviral plasmid vectors. Oligos containing the microRNA sequences are cloned into the TRC2-pLKO-puro vector. Co-transfection of this vector into the appropriate cell line with compatible packaging plasmids produces viral particles that can be used to transduce mammalian cells. The polymerase II promoter, elongation factor 1 alpha (EF1A), was chosen to drive miRNA expression needed for reverse transcription of viral RNA and integration of viral DNA into the host cell genome. Additionally, the Woodchuck Hepatitis Post-Transcriptional Regulatory element allowing for enhanced expression of transgenes delivered by lentiviral vectors. This lentiviral vector also carries a puromycin resistance gene for selection of cells. Unlike murine-based MMLV or MSCV retroviral systems, lentiviral-based particles permit efficient infection and integration of the specific miRNA construct into differentiated and non-dividing cells, such as neurons and dendritic cells.

The breast cancer stem cells contribute to the initiation, progression, recurrence, metastasis as well as resistance of breast cancer. However, the mechanisms underlying the maintenance of breast cancer stemness have not been fully understood. TCGA and GEO data were used
