Transcription profiling by array of 4T1 murine breast carcinoma cells and derived cell lines resistant to photodynamic therapy induced by novel porphyrin-based photosensitizers and temoporfin

Project description:The efficacy of photodynamic therapy for treating premalignant and malignant tumors is often limited by the emerging resistant tumor cells. We have developed experimental model systems to study the mechanisms associated with resistance to photodynamic therapy induced by structurally similar photosensitizers (two novel porphyrin-based photosensitizers and temoporfin) in mouse mammary carcinoma cell line 4T1. Photodynamic therapy resistant clones were obtained in vitro by exposure to constant photosensitizer concentration and irradiation with increasing light doses.

Effects of fucosylation inhibitors on ATRA differentiation in myeloid leukemia cells

Project description:Differentiation therapy with all-trans retinoic acid (ATRA) is well established for acute promyelocytic leukemia (APL). However, the narrow application and tolerance development of ATRA remain to be improved. In this study, we challenged glycosylation inhibitor to obtain better efficiency than ATRA alone. As a result, we found that the combination of fucosylation inhibitor 6-alkynylfucose (6AF) with ATRA have profound effect for differentiation, shown by expression changes of differentiation markers CD11b, CD11c, with significant morphological change in NB4 and HL-60 cells. From lectin blot assay, we found that ATRA or 6AF alone could decrease core fucosylation, the combination of these two agents efficiently decreases the expression of core fucosylation. To reveal molecular mechanisms to reveal 6AF effect for ATRA induced differentiation, we next performed microarray analysis using NB4 cells. From pathway analysis using DAVID software, we found that C-type lectin receptor (CLR) signaling pathway was enriched as high significance. From real time PCR analysis, using NB4 and HL-60 cells, FcRI, CLEC6A, CASP1, IL-1, EGR2/3, the components of CLR, and Akt, were indeed upregulated by 6AF in ATRA induced differentiation. These suggest that the involvement of CLR signaling pathway in 6AF effect of ATRA induced differentiation.

Expression profiling of myeloid leukemia cell treated with vibsanin A, PMA and ATRA

Project description:All-trans retinoic acid (ATRA)-based differentiation therapy has achieved success with the treatment of acute promyelocytic leukemia (APL), a unique subtype of acute myeloid leukemia (AML). However, other subtypes of AML display resistance to ATRA-based treatment. Here, we demonstrate that a novel natural vibsane-type diterpenoid vibsanin A promotes the differentiation of myeloid leukemia cell lines and primary AML blasts. To reveal how vibsanin A function on promoting myeloid leukemia cell differentiation, we analyzed and compared the gene expression profiles in myeloid leukemia HL-60 cells treated with vibsanin A, PMA, and ATRA.

Gene expression profiling of ATRA-resistant NB4-MR4 subclone (R4 cell line) treated with a CHK1 inhibitor i(MK-8776).

Project description:Acute promyelocytic leukemia (APL) is a hematological disease characterized by a balanced reciprocal translocation that leads to the synthesis of the oncogenic fusion protein PML-RARα. APL is mainly managed by a differentiation therapy based on the administration of all-trans retinoic acid (ATRA) and arsenic trioxide (ATO). However, therapy resistance, differentiation syndrome, and relapses require the development of new low-toxicity therapies based on the induction of blasts differentiation. Here, we performed a high-throughput gene expression profile of the ATRA-resistant acute promyelocytic leukemia (APL) cellline (aka R4) treated with a CHK1 inhibitor or DMSO as control.

Expression profiling of ATRA treated NB4 cells

Project description:NB4 is an APL derived cell line, carrying the t(15;17) translocation and expressing the PML/RARa fusion protein. Still, an important question that remains to be addressed is whether PML/RARa target genes are transcriptionally suppressed in primary APL cells and re-activated in all-trans retinoic acid (ATRA) treated NB4 cells. Gene expression of NB4 cells treated with ATRA at different time points were analyzed.
