Zafirlukast attenuates advanced glycation end-products (AGEs)-induced degradation of articular extracellular matrix (ECM)

Zafirlukast, a leukotriene receptor antagonist, has been shown to exert a wide range of effects including anti-asthmatic, anti-inflammatory and oral anti-bacterial. Osteoarthritis is one of the most prevalent age-related public health burdens in the modern world. In the present study, we applied zafirlukast in the treatment of human primary chondrocytes and found that it exerts potent anti-osteoarthritic effects. Zafirlukast inhibited AGEs-induced degradation of the articular extracellular matrix by suppressing expression of MMPs, ADAMTS, NOX-4, generation of ROS, and activation of NF-κB via the IκBα/JNK/AP-1 pathway through targeted inhibition of CysLTR1. These findings suggest that zafirlukast possesses a protective effect against AGEs- induced damage and dysfunction in human chondrocytes.

Reproductive toxicity of a single dose of 1,3-dinitrobenzene in two ages of young adult male rats

These studies evaluated the reproductive response and the possible influence of testicular maturation on the reproductive parameters, in male rats treated with 1,3-dinitrobenzene (m-DNB). Young adult male rats (75 or 105 days of age) were given a single oral dose of 0, 8, 16, 24, 32, or 48 mg/kg of m-DNB and killed at 14 days post-treatment. Mortality and neurotoxicity were observed at 48 mg/kg, but only in the older animals. Epididymis weight, testicular sperm head counts, cauda sperm reserves, and sperm morphology were affected at 16 and 24 mg/kg and higher in the older and younger animals, respectively. Testis weight and sperm motility were affected at 24 mg/kg and higher in both age groups. Histologic changes included maturation depletion of mid and late spermatids at 16 mg/kg and higher, atrophy of a few to many seminiferous tubules at 24 mg/kg and higher, and immature germ cells in the epididymis. The movement and/or mixing of luminal elements in the epididymis appeared to be influenced by severe testicular effects. In separate groups given only the 48 mg/kg dosage, fertilizing ability was lost by 5–6 weeks post-treatment and several animals failed to recover in 5 months. In the breeder males, minimal to extensive degrees of seminiferous tubule atrophy and sloughed germ cells in the epididymis were still present after 175 days. The studies indicated that the lowest dosage to produce reproductive changes was 16 mg/kg with a no-effect level of 8 mg/kg. A few animals suffered protracted or permanent reproductive damage. Since the older animals were more susceptible to both the general and the reproductive toxicity of m-DNB, the less severe reproductive changes in the younger animals cannot be attributed solely to maturational differences in the testis.     

LINC01207 promotes prostate cancer progression by sponging miR-1182 to upregulate AKT3

Prostate cancer (PC) is recognized as a common malignancy in male patients. Long non-coding RNA (lncRNA) has been implicated in the development of PC. Recently, long intergenic non-protein coding RNA 1207 (LINC01207) has been reported to regulate the carcinogenesis of multiple cancer types. However, its role in the progression of PC remains to be determined. The aim of the present study was to investigate the expression profile, clinicopathological implication and molecular mechanism of action of LINC01207 in the progression of PC. LINC01207 expression levels were compared between PC tumor and paired normal tissue samples from The Cancer Genome Atlas. The expression of LINC01207 was further analyzed in PC cell lines and a normal prostatic cell line. The role of LINC01207 in proliferation, migration and invasion of PC cells was examined using small interfering RNA-mediated silencing. Western blot analysis was used to investigate the changes in protein levels underlying the mechanism of action of LINC01207. The role of LINC01207 in tumorigenesis was evaluated in a xenograft model. LINC01207 was upregulated in PC tumor samples from TCGA data compared with paired normal tissue. LINC01207 expression was significantly increased in PC cells and tumor tissues compared with in normal prostate cells (RWPE1) and normal prostate tissues, respectively. Furthermore, LINC01207 silencing inhibited PC cell proliferation and colony formation and induced apoptosis. Mechanistic experiments showed that LINC01207 promoted carcinogenesis by sponging miR-1182 to regulate the protein levels of AKT3 in PC cell lines. Thus, the findings of the present study indicated that LINC01207 might play a role in the tumorigenesis of PC and may serve as a therapeutic target for PC treatment.
