Role of Glucosamine and Chondroitin in the Prevention of Cancer: A Meta-Analysis.
The anti-inflammatory properties of glucosamine and chondroitin suggest that they may have potential effects in cancer prevention. We performed this meta-analysis to assess the protective function of glucosamine and/or chondroitin intake against cancer risk. We searched the PubMed, Embase, Web of Science, and China National Knowledge Infrastructure (CNKI) databases. The odds ratio (OR), corresponding to the 95% confidence interval (95% CI), was used to assess the association between chondroitin and/or glucosamine intake and cancer risk. Thirteen studies met the inclusion criteria, with 1,690,918 participants and 55,045 cancer cases. Overall, chondroitin and/or glucosamine intake was associated with a lower risk of colorectal cancer (OR = 0.91, 95% CI, 0.87-0.94) and lung cancer (OR = 0.84, 95% CI, 0.79-0.89). Subgroup analysis supported the protective effect of different SYSADOAs (chondroitin and/or glucosamine) intake. However, the protective effect was not observed in the only chondroitin intake group and in the NSAIDs group. Our meta-analysis found that the intake of glucosamine and/or chondroitin decreased the risk of colorectal and lung cancers. Moreover, NSAIDs use may have a synergistic protective effect.

[Hereditary Skeletal and Skin Disorders Caused by Defects in the Biosynthesis of Chondroitin/Dermatan Sulfate, and Molecular Mechanisms of Pulmonary Metastasis].
The roles of chondroitin sulfate (CS) and dermatan sulfate (DS) have been demonstrated in various biological events such as the construction of the extracellular matrix, tissue development, and cell signaling through interactions with extracellular matrix components, morphogens, and growth factors. Human genetic diseases, including skeletal abnormalities, connective tissue diseases, and heart defects, were reported to be caused by mutations in the genes encoding glycosyltransferases, epimerases, and sulfotransferases that are responsible for the biosynthesis of CS and DS. Glycobiological approaches revealed that mutations in CS- and DS-biosynthetic enzymes led to reductions in their enzymatic activities and in the levels of CS and DS. Furthermore, CS at the surface of tumor cells plays a key role in pulmonary metastasis. A receptor for advanced glycation end-products (RAGE) was predominantly expressed in the lung, and was identified as a functional receptor for CS chains. CS and anti-RAGE antibodies inhibited the pulmonary metastasis of not only Lewis lung carcinoma but also B16 melanoma cells. Hence, RAGE and CS are potential targets of drug discovery for pulmonary metastasis and a number of other pathological conditions involving RAGE in the pathogenetic mechanism. This review provides an overview of glycobiological studies on characterized genetic disorders caused by the impaired biosynthesis of CS, as well as DS, and on the pulmonary metastasis of Lewis lung carcinoma cells involving CS and RAGE.

Inhalable Lactoferrin/Chondroitin-Functionalized Monoolein Nanocomposites for Localized Lung Cancer Targeting.
Localized drug delivery to lung cancer can overcome the limitations of systemic nanocarriers including low drug amounts reaching lung tissues and severe off-target toxicity. The current work presented novel inhalable nanocomposites as noninvasive platforms for lung cancer therapy. Nanoparticulate liquid crystals (LCNPs) based on monoolein were developed for synergistic co-encapsulation of the cytotoxic chemotherapeutic drug, pemetrexed, and the phytoherbal drug, resveratrol (PEM-RES-LCNPs). For active tumor targeting, lactoferrin (LF) and chondroitin sulfate (CS), natural polymers with intrinsic tumor-targeting capabilities, were exploited to functionalize the surface of LCNPs using a layer-by-layer (LbL) self-assembly approach. To maximize their deep lung deposition, LF/CS-coated PEM-RES-LCNPs were then microencapsulated within various carriers to obtain inhalable nanocomposites via spray-drying techniques. The inhalable dry powder nanocomposites prepared using a mannitol-inulin-leucine (1:1:1 wt) mixture displayed superior in vitro aerosolization performance (2.72 μm of MMAD and 61.6% FPF), which ensured deep lung deposition. In lung cancer-bearing mice using urethane as a chemical carcinogen, the inhalable LF/CS-coated PEM-RES-LCNP nanocomposites showed superior antitumor activity as revealed by a considerable decrease of the average lung weight, reduced number and diameter of cancerous lung foci, decreased expression of VEGF-1, and increased expression of active caspase-3 as well as reduced Ki-67 expression compared to the spray-dried free PEM/RES powder mixture and positive control. Moreover, the in vivo fluorescence imaging confirmed successful lung deposition of the inhalable nanocomposites. Conclusively, the inhalable liquid crystalline nanocomposites elaborated in the current work could open new avenues for noninvasive lung cancer treatment.

Inhalable lactoferrin-chondroitin nanocomposites for combined delivery of doxorubicin and ellagic acid to lung carcinoma.
The use of inhalable nanomedicines can overcome the Enhanced permeation and retention effect (EPR)-associated drawbacks in lung cancer therapy via systemic nanomedicines.. We developed a lactoferrin-chondroitin sulfate nanocomplex for the co-delivery of doxorubicin and ellagic acid nanocrystals to lung cancer cells. Then, the nanocomplex was converted into inhalable nanocomposites via spray drying.. The resulting 192.3 nm nanocomplex exhibited a sequential faster release of ellagic acid, followed by doxorubicin. Furthermore, the nanocomplex demonstrated superior cytotoxicity and internalization into A549 lung cancer cells mediated via Tf and CD44 receptors. The inhalable nanocomposites exhibited deep lung deposition (89.58% fine particle fraction [FPF]) with powerful antitumor efficacy in lung cancer bearing mice.. Overall, inhalable lactoferrin-chondroitin sulfate nanocomposites would be a promising carrier for targeted drug delivery to lung cancer.

Use of glucosamine and chondroitin and lung cancer risk in the VITamins And Lifestyle (VITAL) cohort.
Inflammation plays an important role in lung carcinogenesis. Epidemiologic studies have reported inverse associations of non-steroidal anti-inflammatory drug (NSAID) use and lung cancer risk. Previously, we found that ever use of glucosamine and chondroitin, which have anti-inflammatory properties, were inversely associated with lung cancer risk. After an additional year of follow-up, we further examined the association including frequency/duration of use, interaction with factors associated with inflammation, and lung cancer histology.. Participants were members of the VITamins And Lifestyle cohort. Adults, aged 50-76 years, who were residents of western Washington State, completed a baseline questionnaire in 2000-2002 (n = 76,904). Participants were queried on their use of glucosamine and chondroitin, over the 10 years prior to baseline, and categorized as nonuser, low use < 4 days/week or < 3 years, or high use ≥ 4 days/week and ≥ 3 years. Lung cancer cases (n = 808) were ascertained through linkage to the Surveillance, Epidemiology, and End Results cancer registry.. High 10-year use of glucosamine [hazard ratio (HR), 0.77; 95% CI: 0.56-1.07; p trend = 0.04] but not chondroitin was associated with a reduction in lung cancer risk. The association with glucosamine was limited to adenocarcinoma (HR, 0.49; 95% CI: 0.27-0.90; p trend <0.01) and was not modified by NSAID use or smoking status.. Our results for glucosamine use are similar to the prior human studies of NSAID use and lung cancer, both in magnitude and the limitation of the association to adenocarcinoma. Unlike NSAIDs, glucosamine has no known adverse effects. Although confirmatory studies are needed, glucosamine is an attractive candidate for lung cancer chemoprevention.

Associations of herbal and specialty supplements with lung and colorectal cancer risk in the VITamins and Lifestyle study.
Millions of Americans use dietary supplements with little knowledge about their benefits or risks. We examined associations of various herbal/specialty supplements with lung and colorectal cancer risk. Men and women, 50 to 76 years, in the VITamins And Lifestyle cohort completed a 24-page baseline questionnaire that captured duration (years) and frequency (days per week) of use of commonly used herbal/specialty supplements. Dose was not assessed due to the lack of accurate potency information. Supplement exposure was categorized as "no use" or "any use" over the previous 10 years. Hazard ratios (HR) were estimated by multivariate Cox regression models. Incident lung (n = 665) and colorectal cancers (n = 428) were obtained from the Surveillance, Epidemiology, and End Results cancer registry. Any use of glucosamine and chondroitin, which have anti-inflammatory properties, over the previous 10 years, was associated with significantly lower lung cancer risk: HR 0.74 [95% confidence interval (95% CI), 0.58-0.94] and HR 0.72 (95% CI, 0.54-0.96) and colorectal cancer risk: HR 0.73 (95% CI, 0.54-0.98) and HR 0.65 (95% CI, 0.45-0.93), respectively. There were also statistically significantly inverse associations of fish oil: HR 0.65 (95% CI, 0.42-0.99), methylsulfonylmethane: HR 0.46 (95% CI, 0.23-0.93), and St. John's wort: HR 0.35 (95% CI, 0.14-0.85) with colorectal cancer risk. In contrast, garlic pills were associated with a statistically significant 35% elevated colorectal cancer risk. These results suggest that some herbal/specialty supplements may be associated with lung and colorectal cancer risk; however, these products should be used with caution. Additional studies examining the effects of herbal/specialty supplements on risk for cancer and other diseases are needed.
