Sonic hedgehog (Shh) signal transduction via the G-protein-coupled receptor, Smoothened, is required for proliferation of cerebellar granule neuron precursors (CGNPs) during development. Activating mutations in the Hedgehog pathway are also implicated in basal cell carcinoma and medulloblastoma, a tumor of the cerebellum in humans. However, Shh signaling interactions with cell cycle regulatory ...
Accumulating evidence shows that androgen receptor (AR) activation and signaling plays a key role in growth and progression in all stages of prostate cancer, even under low androgen levels or in the absence of androgen in the castration-resistant prostate cancer. Sustained activation of AR under androgen-deprived conditions may be due to its interaction with co-activators, such as p52 NF-κB sub...
Medulloblastoma (MB) is the most common malignant tumor of the central nervous system in children. Accumulating evidence suggests a major role for the activation of the sonic hedgehog (SHH) signaling pathway in the development of MB cells; however, the mechanisms underlying the effect of this pathway on tumor survival and growth remain poorly understood. The Gli family zinc finger 1 (Gli1) tran...
BACKGROUND AND OBJECTIVES To evaluate the long-term prognostic value of the combination of the EORTC risk calculator and proapoptotic, antiapoptotic, proliferation, and invasiveness molecular markers in predicting the outcome of intermediate- and high-risk non-muscle-invasive bladder cancer (NMIBC) treated with intravesical Bacille Calmette-Guérin (BCG) therapy. MATERIALS AND METHODS This stu...
Somatic stem cells can divide to generate additional stem cells (expansion) or more differentiated cell types (differentiation), which is fundamental for tissue formation during embryonic development and tissue homeostasis during adulthood (1). Currently, great efforts are invested towards controlling the switch of somatic stem cells from expansion to differentiation because this is thought to ...
Virtually all cases of mantle cell lymphoma (MCL) carry the t(11;14)(q13;q32) translocation, leading to the juxtaposition of the CCND1/CYCLIND1 gene to the immunoglobulin heavy chain (IGH) joining region, resulting in cyclin D1 mRNA and protein overexpression.1-3 The existence of “true” MCL negative for cyclin D1 has been controversial but was recently substantiated by gene expression profiling...

A survivin siRNA expression vector was transfected into glioma U-87MG cells and these cells were then treated with paclitaxel. The results showed that survivin-specific siRNA combined with paclitaxel treatment synergistically inhibited glioma U-87MG cell proliferation and promoted apoptosis. This treatment also inhibited the expression of the cell cycle regulatory proteins, survivin, cyclinD1, ...
