RESUMO

The objective of this study was to investigate the effect of low-molecular-weight fish collagen (valine-glycine-proline-hydroxyproline-glycine-proline-alanine-glycine; LMWCP) on H2O2- or LPS-treated primary chondrocytes and monoiodoacetate (MIA)-induced osteoarthritis rat models. Our findings indicated that LMWCP treatment exhibited protective effects by preventing chondrocyte death and reducing matrix degradation in both H2O2-treated primary chondrocytes and cartilage tissue from MIA-induced osteoarthritis rats. This was achieved by increasing the levels of aggrecan, collagen type I, collagen type II, TIMP-1, and TIMP-3, while simultaneously decreasing catabolic factors such as phosphorylation of Smad, MMP-3, and MMP-13. Additionally, LMWCP treatment effectively suppressed the activation of inflammation and apoptosis pathways in both LPS-treated primary chondrocytes and cartilage tissue from MIA-induced osteoarthritis rats. These results suggest that LMWCP supplementation ameliorates the progression of osteoarthritis through its direct impact on inflammation and apoptosis in chondrocytes.

RESUMO

To target benign prostatic hyperplasia (BPH) as a common urinary disease in old men, in the current study, the antiproliferative and apoptotic mechanism of SH-PRO, a mixture of Angelica gigas and Astragalus membranaceus (2:1), was evaluated in BPH-1 cells and rats with testosterone-induced BPH. Herein, SH-PRO significantly reduced the viability of BPH-1 cells and dihydrotestosterone (DHT)-treated RWPE-1 cells. Also, SH-PRO increased the sub-G1 population in BPH-1 cells and consistently attenuated the expression of pro-PARP, pro-caspase 3, Bcl2, FOXO3a, androgen receptor (AR), and prostate-specific antigen (PSA) in BPH-1 cells and DHT-treated RWPE-1 cells. Of note, SH-PRO generated reactive oxygen species (ROS) in BPH-1 cells, while ROS inhibitor N-acetyl-l-cysteine (NAC) disturbed the ability of SH-PRO to reduce the expression of pro-PARP, FOXO3a, catalase, SOD, and increase sub-G1 population in BPH-1 cells. Furthermore, oral treatment of SH-PRO significantly abrogated the weight of the prostate in testosterone-treated rats compared to BPH control with the reduced expression of AR, PSA, and DHT and lower plasma levels of DTH, bFGF, and EGF with no toxicity. Overall, these findings highlight the antiproliferative and apoptotic potential of SH-PRO via ROS-mediated activation of PARP and caspase 3 and inhibition of FOXO3a/AR/PSA signaling as a potent anti-BPH candidate.

RESUMO

We evaluated the effect of artichoke leaf extract (ALE) on the livers of mice with non-alcoholic fatty liver disease (NAFLD) induced by high-fat/high-fructose diet and H2O2-treated HepG2 cells, as well as the mechanism underlying its hepatoprotective effects. Supplementation with ALE suppressed the NAFLD-induced increases in serum lipids, bilirubin, gamma-glutamyl transferase, aspartate transaminase (AST), and alanine aminotransferase. In addition, we observed that supplementation with ALE attenuated the increases in antioxidant enzyme activity, mRNA levels of proinflammatory cytokines, and apoptosis signaling pathways caused by a high-fat/high-fructose diet. We found that ALE treatment suppressed inflammation and apoptosis caused by H2O2-induced oxidative stress in HepG2 cells. These findings suggest that ALE supplementation directly suppresses inflammation and apoptosis in hepatocytes during the development of NAFLD. Based on these results, we suggest that supplementation with ALE may be useful for preventing the progression of liver diseases, including hepatic steatosis and non-alcoholic steatohepatitis.

RESUMO

BACKGROUND: Systemic treatments for advanced non-small cell lung cancer (NSCLC) have modest survival benefits but high toxicity. Rhus verniciflua Stokes (RVS), the lacquer tree, is an ancient traditional medicine being used for the treatment of cancer. We investigated the efficacy and safety of allergen-removed RVS extract (aRVS) for the prolongation of survival in NSCLC after the failure of first-line or second-line chemotherapy. PATIENTS AND METHODS: We reviewed the medical records of 40 patients who were treated with aRVS for previously treated, advanced NSCLC at the M×µ Integrative Cancer Center, Korea, between June 2006 and June 2009. The primary objective of this study was to assess overall survival. Secondary objectives included assessments of disease control rates, progression-free survival, and the safety of aRVS treatment. RESULTS: The median survival time was 8.4 months with a 1-year survival of 40%. The disease control rate was 63.6%, and the median progression-free survival interval was 3.9 months. Patients who had better performance status and adenocarcinoma experienced more favorable outcomes in terms of overall survival. in aRVS treatment were negligible, with the most common drug-related adverse events being mild epigastric pain and itching skin. Hematologic toxicity was absent. CONCLUSIONS: Survival data and favorable levels of tolerability suggest the potential of aRVS treatment in previously treated patients with advanced NSCLC. Treatment with aRVS might be a viable alternative in patients for whom chemotherapy is not feasible, or who refuse chemotherapy.

RESUMO

There is no established protocol proven to be beneficial for treatment of hepatocellular carcinoma recurrence after liver transplantation. Only a few reports have shown direct treatment by surgery or ablation to be independent predictors of survival for localized recurrence. Moreover, the necessity of immunosuppression to prevent allograft rejection makes many physicians hesitate to administer systemic chemotherapy. This case report documents a case in which the administration of an herbal product, an extract of the lacquer tree, Rhus verniciflua Stokes, was associated with a decrease in the size of lung metastases in a patient with recurrent hepatocellular carcinoma after liver transplantation refractory to doxorubicin. This patient experienced prolonged survival compared with average survival times and little toxicity.

RESUMO

An unexpected outbreak of boll weevils, Anthonomus grandis, an insect pest of cotton, across the Southern Rolling Plains (SRP) eradication zone of west-central Texas, USA, was detected soon after passage of Tropical Storm Erin through the Winter Garden district to the south on 16 August 2007. The synchrony and broad geographic distribution of the captured weevils suggest that long-distance dispersal was responsible for the reinvasion. We integrated three types of assessment to reconstruct the geographic origin of the immigrants: (i) DNA fingerprinting; (ii) pollen fingerprinting; and (iii) atmospheric trajectory analysis. We hypothesized the boll weevils originated in the Southern Blacklands zone near Cameron, or in the Winter Garden district near Uvalde, the nearest regions with substantial populations. Genetic tests broadly agree that the immigrants originated southeast of the SRP zone, probably in regions represented by Uvalde or Weslaco. The SRP pollen profile from weevils matched that of Uvalde better than that of Cameron. Wind trajectories supported daily wind-aided dispersal of weevils from the Uvalde region to the SRP from 17 to 24 August, but failed to support migration from the Cameron region. Taken together the forensic evidence strongly implicates the Winter Garden district near Uvalde as the source of reinvading boll weevils.
