The efficacy of chimeric antigen receptor (CAR) immunotherapy in animal models for solid tumors: A systematic review and meta-analysis
<div><p>Background</p><p>Most recently, an emerging theme in the field of tumor immunology predominates: chimeric antigen receptor (CAR) therapy in treating solid tumors. The number of related preclinical trials was surging. However, an evaluation of the effects of preclinical studies remained absent. Hence, a meta-analysis was conducted on the efficacy of CAR in animal models for solid tumors.</p><p>Methods</p><p>The authors searched PubMed/Medline, Embase, and Google scholar up to April 2017. HR for survival was extracted based on the survival curve. The authors used fixed effect models to combine the results of all the trials. Heterogeneity was assessed by I-square statistic. Quality assessment was conducted following the Stroke Therapy Academic Industry Roundtable standard. Publication bias was assessed using Egger's test.</p><p>Results</p><p>Eleven trials were included, including 54 experiments with a total of 362 animals involved. CAR immunotherapy significantly improved the survival of animals (HR: 0.25, 95% CI: 0.13–0.37, P < 0.001). The quality assessment revealed that no study reported whether allocation concealment and blinded outcome assessment were conducted, and only five studies implemented randomization.</p><p>Conclusions</p><p>This meta-analysis indicated that CAR therapy may be a potential clinical strategy in treating solid tumors.</p></div

Characterization of a Novel Butachlor Biodegradation Pathway and Cloning of the Debutoxylase (Dbo) Gene Responsible for Debutoxylation of Butachlor in Bacillus sp. hys‑1
Bacillus sp. strain hys-1, which
was isolated from active sludge, could degrade >90% butachlor at
a
concentration of 100 mg/L within 7 days. The present work revealed
that strain hys-1 could mineralize butachlor via the following pathway:
butachlor was initially metabolized to 2-chloro-<i>N</i>-(2,6-diethylphenyl)-<i>N</i>-methylacetamide by debutoxylation
and then transformed to form 2-chloro-<i>N</i>-(2,6-diethylphenyl)Âacetamide
by N-demethylation. Subsequently, it was converted to 2,6-diethylaniline
and further mineralized into CO<sub>2</sub> and H<sub>2</sub>O. In
addition, the catalytic efficiency of crude cell extracts descended
as follows: alachlor > acetochlor > butachlor. Furthermore,
a novel
744 bp gene responsible for transforming butachlor into 2-chloro-<i>N</i>-(2,6-diethylphenyl)-<i>N</i>-methylacetamide
was cloned from strain hys-1 and the encoding debutoxylase was designated
Dbo. Then Dbo was expressed in Escherichia coli BL21 (DE3) and purified using Ni–nitrilotriacetic acid affinity
chromatography. Dbo displayed the highest activity against butachlor
at pH 6.5 and 30 °C. Metal ions played an important role in Dbo
activity. To the best of the authors’ knowledge, this is the
first report that strain hys-1 can mineralize butachlor by a novel
metabolic mechanism and the first identification of a gene encoding
butachlor debutoxylase
