  • Patent number: 11873533
    Abstract: Disclosed is a method of detecting and quantifying genomic and gene expression alterations using RNA in a biological sample. The disclosed method may include determining presence or absence of the genomic alteration and/or determining presence or absence of the gene expression and/or quantifying the level of the gene expression, by performing variant calling of the sequence alignment obtained from the disclosed method. Variant calling may comprise the steps of identifying differences between a consensus read and a reference genome based on the sequence alignment from the disclosed method; and determining the read count of sequence alignments comprising genomic alteration. The genomic alteration may be an insertion (such as a duplication), a deletion, a single nucleotide variant, or combinations thereof. Also disclosed is a kit for detecting and quantifying genomic and gene expression alterations using RNA in a biological sample.

  • Patent number: 9901649
    Abstract: Amphiphilic block copolymers (BCPs) were prepared comprising a poly(ethylene oxide) block and a biodegradable polycarbonate block functionalized with disulfide groups and carboxylic acid groups. The BCPs form self-assembled micellar particles in aqueous solution that can be loaded with hydrophobic drugs for therapeutic drug delivery. The loaded particles have small particle sizes (<100 nm), narrow particle size distributions, and high drug loading capacity (up to about 50 wt %) based on total dry weight of the loaded particles. Particles loaded with DOX released the DOX in response to changes in pH and glutathione (GSH) redox chemistry. The loaded particles efficiently delivered and released DOX within tumor cells, effectively suppressing growth of the tumor cells at a similar or even lower drug concentration than free DOX. Blank particles containing no DOX did not induce cytotoxicity to cells.
