Objective: Although azelaic acid is effective for treatment of acne and rosacea, the biological activity of azelaic acid and the effect of its combination therapy with minoxidil were not elucidated with regard to hair growth. Materials and Methods: In this study, mouse vibrissae follicles were dissected on day 10 after depilation. Then, the bulb and bulge...
Irx1 and Irx2 are members of the murine Iroquois homeobox (Irx) gene family. In this study, we describe the dynamic expression pattern of these genes during limb development with a focus on digit formation. We further present a comparative expression analysis with Gli genes (Gli1, Gli2, Gli3). Gli1, Gli2, and Gli3 were suggested for candidate regulators of the Irx genes. The expression was stud...
USP21 is a centrosome-associated deubiquitylase (DUB) that has been implicated in the formation of primary cilia - crucial organelles for the regulation of the Hedgehog (Hh) signaling pathway in vertebrates. Here, we identify KCTD6 - a cullin-3 E3-ligase substrate adapter that has been previously linked to Hh signaling - as well as Gli1, the key transcription factor responsible for Hh signal am...
The Sonic hedgehog (Shh) signaling pathway plays a critical role in normal cerebellar development and has been implicated in medulloblastomas, common malignant childhood tumors of the cerebellum. To test whether Shh mis-expression is sufficient for medulloblastoma formation, we used ultrasound biomicroscopy-guided in utero injection of a Shh-expressing retrovirus into the cerebellum of 13.5-day...
Zhi-Zhen-Fang (ZZR), a Traditional Chinese Medicine (TCM) formula, has been clinically used in China to treat drug-resistant colorectal cancer (CRC) patients as an adjuvant. In this study, the efficacy of ZZR in suppressing multidrug resistance (MDR) on CRC was evaluated in vitro and in vivo. We observed that ZZR enhanced the sensitivity of chemotherapeutic drugs and induced apoptosis in a dose...
Prostate cancer is the most common solid tumor in men, and it shares with all cancers the hallmark of elevated, nonhomeostatic cell proliferation. Here we have tested the hypothesis that the SONIC HEDGEHOG (SHH)-GLI signaling pathway is implicated in prostate cancer. We report expression of SHH-GLI pathway components in adult human prostate cancer, often with enhanced levels in tumors versus no...
Emerging studies have indicated that microRNAs are involved in the development and progression of cancer. Here we found that miR-202-3p was frequently down-regulated in gastric cancer tissues. Overexpression of miR-202-3p in gastric cancer cells MKN-28 and BGC-823, markedly suppressed cell proliferation and induced cell apoptosis both in vitro and in vivo. Furthermore, Gli1 expression was frequ...
Hedgehog (Hh) signaling plays an important role in embryonic development, cell maintenance and cell proliferation. Moreover, Hh signaling contributes to the growth of cancer cells. Physalins are highly oxidized natural products with a complex structure. Physalins (1-7) were isolated from Solanum nigrum (Solanaceae) collected in Bangladesh by using our cell-based assay. The isolated physalins in...
Lithium Inhibits Tumorigenic Potential of PDA Cells through Targeting Hedgehog-GLI Signaling Pathway
Hedgehog signaling pathway plays a critical role in the initiation and development of pancreatic ductal adenocarcinoma (PDA) and represents an attractive target for PDA treatment. Lithium, a clinical mood stabilizer for mental disorders, potently inhibits the activity of glycogen synthase kinase 3β (GSK3β) that promotes the ubiquitin-dependent proteasome degradation of GLI1, an important downst...
Activation of the Hedgehog pathway has been implicated in the pathogenesis of several tumor types including myeloid leukemia. Previously we demonstrated that overexpression of Hedgehog downstream mediators GLI1/2 confers an adverse prognosis to patients with acute myeloid leukemia (AML) and is correlated with a FLT3 mutated status. To analyze a possible non-canonical activation of the Hedgehog ...
