Research Associate
Used molecular biology, cell biology, tissue culture, histology, flow cytometry and imaging techniques. Used viral production (shRNA mediated lentivirus, and lentiCRISPR-Cas9 methodology) /or delivery, gene modulation (lentiCRISPR –Cas9, siRNA, shRNA mediated lentivirus) and animal models.
CRISPR-Cas9 knockout screening and its validation: Rift Valley Fever Virus (RVFV)
CRISPR (clustered regularly interspaced short palindromic repeats) - associated nuclease Cas9 used to genetically modify specific genomic loci.
Used lentiviral delivery of a genomic-scale CRISPR-Cas9 knockout (GeCKO) library targeting 18,080 genes enabling both negative and positive selection in human lung cells (A549 cell line).
Human lung A549 cells were screened for resistance to RVFV infection. Used next generation sequencing to identify candidate genes essential for RVFV replication.
To validate these results, inhibited these gene expression (sgRNAs) by lentiCRISPR-Cas9 system, and created knockout stable cell line. The established methodology was used to knockout for prion protein expression by using lentiCRISPR-Cas9 in deer brain cell line
