cRGD grafted siRNA nano-constructs for chemosensitization of gemcitabine hydrochloride in lung cancer treatment.
Article in Pharmaceutical research, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe aim of present investigation was to effectively deliver ribonucleotide reductase subunit 1 (RRM1) targeted siRNA and assess chemo-sensitization of lung cancer cells against Gemcitabine hydrochloride. It was hypothesised that effective and selective delivery of RRM1 siRNA will help in the treatment of lung cancer chemotherapy using Gemcitabine hydrochloride by reducing drug dose and thereby, reduces dose related toxicity of Gemcitabine hydrochloride.
methodsIn this investigation, cRGD grafted siRNA nano-constructs were developed for efficient and targeted intracellular delivery of siRNA. Developed formulations were characterized for gel retardation assay, particle size, zeta potential, cryo transmission electron microscopy, serum stability, in vitro cytotoxicity, qualitative and quantitative cell uptake, gene expression, and chemo-sensitization.
resultsComplete complexation of siRNA with cRGD grafted nano-constructs was found at N/P ratio of 2.0. Naked siRNA was found to degrade within 6 h in presence of 50% serum while nano-constructs protected the complexed siRNA even after 24 h. RRM1 level significantly reduced when siRNA was delivered in nano-construct form as compared to naked siRNA. Pre-exposure of RRM1 siRNA decreased the IC50 value of Gemcitabine hydrochloride 5 folds in A-549 cells compared to Gemcitabine hydrochloride alone.
conclusionThese results suggest the application of present siRNA delivery strategy to potentiate the chemotherapeutic effect by means of chemosensitization which may be utilized for effective and thorough remission of lung cancer.
