  1. p-21 activated kinase 4 promotes proliferation and survival of pancreatic cancer cells through AKT- and ERK-dependent activation of NF-κB pa...

    Oncotarget 5(18):8778 (2014) PMID 25238288

    We investigated the expression and pathobiological significance of p21-activated kinase 4 (PAK4), a gene that was earlier shown to be amplified in a sub-set of PC. Our data demonstrate PAK4 overexpression in PC tissues and cell lines with little or no expression in the normal pancreas. PAK4 silencin...
  2. TALEN-mediated Nanog disruption results in less invasiveness, more chemosensitivity and reversal of EMT in Hela cells.

    Oncotarget 5(18):8393 (2014) PMID 25245189

    Emerging evidence suggests that Nanog is involved in cervical tumorigenesis. However, the regulating role of Nanog in tumorigenesis and chemosensitivity are still poorly understood. In this study, Nanog was disrupted by transcription activator-like effector nucleases (TALEN) in Hela cells and its ex...
  3. Selective JAK2/ABL dual inhibition therapy effectively eliminates TKI-insensitive CML stem/progenitor cells.

    Oncotarget 5(18):8637 (2014) PMID 25226617

    We have recently identified an AHI-1-BCR-ABL-JAK2 protein complex that contributes to the transforming activity of BCR-ABL and IM-resistance in CML stem/progenitor cells. JAK2 thus emerges as an attractive target for improved therapies, but off-target effects of newly developed JAK2 inhibitors on no...
  4. Induced cancer stem-like cells as a model for biological screening and discovery of agents targeting phenotypic traits of cancer stem cell.

    Oncotarget 5(18):8665 (2014) PMID 25228591

    We recently established a CSC-like model using induced pluripotent stem cell (iPSC) technology to reprogram and partially differentiate human mammary epithelial MCF-10A cells. Using the induced CSC-like (iCSCL) model, we developed a phenotypic drug assay system to identify agents that inhibit the st...
  5. Regulatory roles of LINE-1-encoded reverse transcriptase in cancer onset and progression.

    Oncotarget 5(18):8039 (2014) PMID 25327556

    LINE-1 retrotransposons encode the reverse transcriptase (RT) enzyme, required for their own mobility, the expression of which is inhibited in differentiated tissues while being active in tumors. Experimental evidence indicate that the inhibition of LINE-1-derived RT restores differentiation in canc...
  6. Targeting STAT6 in PMBL.

    Oncotarget 5(17):7216 (2014) PMID 25277174

  7. TRIM8 anti-proliferative action against chemo-resistant renal cell carcinoma.

    Oncotarget 5(17):7446 (2014) PMID 25277184

    We identified TRIM8 as a new p53 modulator, which stabilizes p53 impairing its association with MDM2 and inducing the reduction of cell proliferation. In this paper we demonstrated that TRIM8 deficit dramatically impairs p53-mediated cellular responses to chemotherapeutic drugs and that TRIM8 is dow...
  8. Chemoprevention of metastasis.

    Oncotarget 5(16):6556 (2014) PMID 25179303

    Comment on: Xu L, et al. COX-2 inhibition potentiates antiangiogenic cancer therapy and prevents metastasis in preclinical models. Sci Transl Med. 2014 25; 6:242ra84.
  9. MiR-497 downregulation contributes to the malignancy of pancreatic cancer and associates with a poor prognosis.

    Oncotarget 5(16):6983 (2014) PMID 25149530

    We screened miRNAs associated with drug resistance in pancreatic cancer, and identified a panel of miRNAs dysregulated in gemcitabine-resistance pancreatic cancer cells, including 13 downregulated miRNAs and 20 upregulated miRNAs. Further studies focusing on miR-497 demonstrated that miR-497 suppres...
  10. A generic cycling hypoxia-derived prognostic gene signature: application to breast cancer profiling.

    Oncotarget 5(16):6947 (2014) PMID 25216520

    We exposed 20 tumor cell lines to repeated periods of hypoxia/reoxygenation to determine a transcriptomic CycHyp signature and used clinical data sets from 2,150 breast cancer patients to estimate a prognostic Cox proportional hazard model to assess its prognostic performance. The CycHyp prognostic...
