Epithelial–mesenchymal transition (EMT) has been linked to cancer stem-like (CD44+) cell in the prostate cancer (PCa) metastasis. However, the molecular mechanism remains elusive. Here, we found EMT contributed to metastasis in PCa patients failed in androgen deprivation therapy (ADT). Castration TRAMP model also proved PCa treated with ADT promoted EMT with increased CD44+ stem-like cells. Switched CD44+ cell to EMT cell is a key step for luminal PCa cell metastasis. Our results also suggested ADT might go through promoting TGFβ1-CD44 signaling to enhance swift to EMT. Targeting CD44 with salinomycin and siRNA could inhibit cell transition and decrease PCa invasion. Together, cancer stem-like (CD44+) cells could be the initiator cells of EMT modulated by TGFβ1-CD44 signaling. Combined therapy of ADT with anti-CD44 may become a new potential therapeutic approach to battle later stage PCa. 相似文献

Hyaluronan-binding protein 1 (HABP1) is a protein with high affinity for HA, and has been reported to be upregulated in cancer cells. In this study, we show that silencing HABP1 inhibits proliferation, and suppresses the migration and invasion ability of breast cancer cell lines. In addition, silencing HABP1 remarkably slows down tumor growth in mice. We examined the correlation between HABP1 expression and clinicopathological parameters using immunohistochemistry in patients with breast cancer. The results indicate that HABP1 is overexpressed in cancer tissue, and its high levels are related to lymph node metastasis (P = 0.032) and tumor stage (P = 0.041). Moreover, high HABP1 expression is correlated with poor overall survival in breast cancer patients (P = 0.018), and is a signifi cant independent prognostic indicator. Our fi ndings suggest that HABP1 regulates proliferation and migration of breast cancer cells. HABP1 may be a useful independent predictor of outcomes in patients with breast cancer. 相似文献

骨质疏松是一种渐进性的代谢性疾病,中医认为肝脾肾的亏虚和血瘀均可诱发骨质疏松。其最主要病因是肾虚累及肝脾导致气血不足而血瘀,加上先天禀赋不足后天调养失宜致使筋脉失养骨枯髓减而致骨痿。本文详细地分析了中医对骨质疏松病因病机的认识,探索了中医药在治疗骨质疏松方面面临的机遇与挑战。中药的药食同源性和骨质疏松病程的长期性决定了中医药在治疗骨质疏松方面具有无可比拟的优势。而科学研究中医药,合理评价其安全性,是中医药发挥其临床治疗优势的关键。 相似文献

Vascularization remains a critical challenge in dermal tissue regeneration. In this study, a vascular endothelial growth factor (VEGF165) and angiopoietin‐1 (Ang‐1) dual gene coexpression vector that encoded green fluorescent protein (GFP) was constructed from an arginine–glycine–aspartic acid‐modified adenovirus. Silk fibroin (SF) scaffolds loaded with adenovirus vectors were fabricated by freeze‐drying method. In vitro, the human endothelial‐derived cell line EA.hy926 was infected with adenovirus vectors and then expressed GFP, secreted VEGF165 and Ang‐1, and promoted cell proliferation effectively. The VEGF165 and Ang‐1 genes loaded in the SF scaffolds significantly promoted the formation of abundant microvascular networks in the chick embryo chorioallantoic membrane. In vivo, angiogenic genes loaded in the scaffolds promoted vascularization and collagen deposition in scaffolds, thus effectively accelerating dermal tissue regeneration in a dorsal full‐thickness skin defect wound model in Sprague–Dawley rats. In conclusion, SF scaffolds loaded with arginine–glycine–aspartic acid‐modified adenovirus vectors encoding VEGF165 and Ang‐1 could stimulate the formation of vascular networks through the effective expression of target genes in vascular endothelial cells, thereby accelerating the regeneration of dermal tissue. 相似文献

Based on first-principles calculations, the properties of B-doped graphane under high pressure up to 380 GPa are investigated. We find that B-doped graphane undergoes a phase transition from phase-α to phase-β at 6 GPa. Different from pristine graphane (X. Wen, L. Hand, V. Labet, T. Yang, R. Hoffmann, N. W. Ashcroft, A. R. Oganov and A. O. Lyakhov, Graphane sheets and crystals under pressure, Proc. Natl. Acad. Sci. U. S. A., 2011, 108, 6833–6837), phase-γ of B-doped graphane is kinetically unstable. The calculated superconducting transition temperature of B-doped graphane at ambient pressure is 45 K, and pressurization can increase the transition temperature notably, e.g., 77 K at 100 GPa. Both the electronic states at the Fermi level and the electron–phonon coupling are mainly contributed by B–C characteristics, indicating that the B-doping plays a key role in the superconductivity.Under high-pressure, the most stable two configurations of B-doped graphane are phase-α and phase-β, and pressurization can increase their Tc significantly. 相似文献
