Abstract
Objective: Aloin, the main active component in Aloe vera (L.) Burm. f., has shown promising anti-tumor effects. This study investigated the impact of aloin in lung squamous cell carcinoma (LUSC) and explored its functional mechanism.
Methods: We analyzed the viability, migration, invasion, proliferation, and apoptosis of two LUSC cell lines after treatment with aloin. Target molecules of aloin and downstream target transcripts of nuclear receptor subfamily 3 group C member 2 (NR3C2) were predicted by bioinformatics. The biological functions of NR3C2 and metallothionein 1 M (MT1M) in the malignant properties of LUSC cells were determined. A co-culture system of LUSC cells with monocyte-derived macrophages was constructed. Mouse xenograft tumor models were generated to analyze the functions of aloin and NR3C2 in the tumorigenic activity of LUSC cells and macrophage polarization in vivo.
Results: Aloin suppressed malignant properties of LUSC cells in vitro. However, these effects were negated by the silencing of NR3C2. NR3C2 was found to activate MT1M transcription by binding to its promoter. Additional upregulation of MT1M suppressed the malignant behavior of LUSC cells augmented by NR3C2 silencing. Analysis of the M1 and M2 markers/cytokines in the macrophages or the culture supernatant revealed that aloin treatment or MT1M overexpression in LUSC cells enhanced M1 polarization while suppressing M2 polarization of macrophages, whereas NR3C2 silencing led to reverse trends. Consistent findings were reproduced in vivo.
Conclusion: This study demonstrated that aloin activates the NR3C2/MT1M axis to suppress the malignant behavior of LUSC cells and M2 macrophage polarization.

期刊介绍:
The predecessor of JIM is the Journal of Chinese Integrative Medicine (Zhong Xi Yi Jie He Xue Bao). With this new, English-language publication, we are committed to make JIM an international platform for publishing high-quality papers on complementary and alternative medicine (CAM) and an open forum in which the different professions and international scholarly communities can exchange views, share research and their clinical experience, discuss CAM education, and confer about issues and problems in our various disciplines and in CAM as a whole in order to promote integrative medicine.
JIM is indexed/abstracted in: MEDLINE/PubMed, ScienceDirect, Emerging Sources Citation Index (ESCI), Scopus, Embase, Chemical Abstracts (CA), CAB Abstracts, EBSCO, WPRIM, JST China, Chinese Science Citation Database (CSCD), and China National Knowledge Infrastructure (CNKI).
JIM Editorial Office uses ThomsonReuters ScholarOne Manuscripts as submitting and review system (submission link: http://mc03.manuscriptcentral.com/jcim-en).
JIM is published bimonthly. Manuscripts submitted to JIM should be written in English. Article types include but are not limited to randomized controlled and pragmatic trials, translational and patient-centered effectiveness outcome studies, case series and reports, clinical trial protocols, preclinical and basic science studies, systematic reviews and meta-analyses, papers on methodology and CAM history or education, conference proceedings, editorials, commentaries, short communications, book reviews, and letters to the editor.
Our purpose is to publish a prestigious international journal for studies in integrative medicine. To achieve this aim, we seek to publish high-quality papers on any aspects of integrative medicine, such as acupuncture and traditional Chinese medicine, Ayurveda medicine, herbal medicine, homeopathy, nutrition, chiropractic, mind-body medicine, taichi, qigong, meditation, and any other modalities of CAM; our commitment to international scope ensures that research and progress from all regions of the world are widely covered. These ensure that articles published in JIM have the maximum exposure to the international scholarly community.
JIM can help its authors let their papers reach the widest possible range of readers, and let all those who share an interest in their research field be concerned with their study.
