Xentry
Xentry is a cell-penetrating peptide (CCP) consisting of only 7 amino acids of hepatitis B virus: LCLRPVG. Xentry-linked anti-B-raf antibodies and siRNAs demonstrates the capability to kill B-raf-dependent melanoma cells. Xentry alone or conjugated to β-galactosidase leads to its delivery to most tissues in mice, except circulating blood cells. Xentry can be used for the delivery of large molecules (antibodies, siRNA, enzymes) .

Description
In Vitro
Xentry (10 μM) penetrates adherent cells energy-dependently, including HepG2 (liver), C32 (melanoma), DU145 (prostate), H441 (lung), BT474 (breast), Cos (kidney), and Rin-m5F (pancreatic b-cell) cell lines, but not nonadherent resting blood cells[1].
Xentry (10-20 μM, 4 h) conjugated to β-galactosidase is internalized by living HepG2 cells, and enters cells via a syndecan pathway[1].
Xentry (1 h) effectively delivers antibodies and siRNA to melanoma cells, inducing apoptosis of B-raf-dependent melanoma cells[1].

In Vivo
TAMRA-labelled Xentry (2-100 μg/mL, i.v., single dose) successfully delivers the macromolecular complex to multiple tissues in Balb/c mice, specifically enriching in small intestinal epithelial cells and marginal sinus of the spleen[1].

RNA interference technology
RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing gene transcription or activating RNA degradation. This mechanism was discovered in plants in 1998 by Andrew Fire and Craig Mello. Today, this phenomenon can be observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals.
