The function of belayed vesicles as productive transporters for drugs, immunizations, indicative specialists, and other bioactive operators has prompted a fast headway in the liposomal drug conveyance system. The pharmacy- elements and pharmacokinetics properties are altered for the liposomal delivery system,which on thewholeleads to an increased the rapeutic index with decreased toxicity. The liposome can be named multilamellar vesicles or unilamellar vesicles, which can be additionally named large unilamellar vesicles (LUV) or small unilamellar vesicles (SUV). The part of liposome as a medication conveyance framework is to convey drug in a controlled way, diminishing unfortunate reactions improving it is in vitro and in vivo action, just as lessening the harmfulness of the medication and upgrading the viability of the exemplified drug. This article gives a review of techniques to the planning of liposome, just as diagnostic strategies for control physical, concoction, and organic boundaries for various kinds of medications.

MiRNAs are important regulators of gene expression and changes in their levels are linked with various pathological states, including solid tumors. MiR-215 has been identified as a tumor suppressor in colorectal cancer (CRC). Following our previous in vitro and in vivo experiments, the aim of this project was to study the possibility of increasing the levels of miR-215 in tumor cells by systemic administration of miRNA mimics in liposomal delivery system in vivo. By subcutaneous xenotransplantation of human cancer cells to NSG mice, CRC model was established. The treatment [miR-215 mimics in liposomes (20 and 40 μg/mouse), control oligonucleotide in liposomes, or saline] was administered repeatedly by i.v. injection via tail-vein. Animals were sacrificed, tumor were dissected and measured by a caliper. Expression of miR-215 in tumors, lungs and liver was quantified by RT-PCR. There was no significant differences in tumor volume and miR-215 expression between all three treatment groups. Therefore, the decrease in tumor volume was not achieved. By comparing the levels of miR-215 in lungs, liver and tumors after the treatment, we suggest that the liposomes are accumulated in the lungs and do not concentrate sufficiently in the tumor site to exert significant tumor-suppressive effect.
