MMCT-mediated chromosome engineering technique applicable to functional analysis of lncRNA and nuclear dynamics

Recent evidence implicated several long noncoding RNA (lncRNA) in gene expression in cis or trans through regulating the local chromosomal architecture. However, the mechanisms underlying the lncRNA mediated silencing of multiple genes remain unknown. We believe that Microcell Mediated Chromosome Transfer (MMCT) is a suitable approach for functional analysis of lncRNAs and nuclear dynamics. MMCT is a unique research technique that can be generally used to transfer a single chromosome from one mammalian cell to another. Transferred chromosomes can be stably maintained as functioning in the recipient cells. Since there is no size limit to introducing genomic locus, an approach using the chromosome transfer technique is suitable for functional analysis of a large chromosomal domain. Here we describe a general strategy of MMCT, applications of which have potential to be an alternative tool of existing gene delivery system.
