Effect of BMP4 overexpression in MycCaP cells on TAMs in ostegenic prostate tumors

Project description:Tumor-associated macrophages (TAMs) play an important role in cancer progression and have been implicated to play a role in prostate cancer. However, TAMs in osteogenic prostate cancer bone metastasis have not been characterized. Here we used a novel osteogenic MycCaP-BMP4 model to study the unique cellular and molecular mechanisms in driving the tumor progression in osteogenic prostate cancer metastasis.

Noggin vs BMP4 overexpression Epidermis

Project description:The study was performed to determine if there were alterations in the total RNA pool among the epidermal keratinocytes of K14 promotor-driven noggin overexpression compared with K14 promotor-driven BMP4 overexpression transgenic animals, which will directly relate to cellular chemistry and immune and sensory function. The total study is also aimed at determining alterations of transcrption factors and/or regulation of gene function, including methylation states and micro RNA control in keratinocytes following sensory challenge, particularly neuropathic and chronic pain conditions. Keywords: Comparison of RNA expression between BMP4-oex and Nog-oex transgenic epidermal keratinocytes Eight-ten epidermis strips were laser captured per animal, and six (6) animals were used per transgenic condition. Recovered RNA samples were pooled from 2 groups of 3 noggin transgenics and 2 groups of 3 BMP4 transgnics to create four pools for hybridization.

Gene expression profiles of tumor-associated macrophages (TAMs) overexpressing miR-511-3p

Project description:Hematopoietic stem/progenitor cells (HS/PCs) were transduced with lentiviral vectors overexpressing OFP and either miR-511-3p or a control, mutated miRNA sequence (miR-511-3p-mut). The transduced HS/PCs were then transplanted in recipient C57BL/6 mice. Tumors (Lewis lung carcinomas, LLC) were injected s.c. 4 weeks after HS/PC transplant. Lentiviral vector-transduced (OFP+), tumor-associated macrophages (TAMs) were isolated 4 weeks after LLC injection by fluorescence-activated cell sorting. Gene expression profiles of TAMs overexpressing either miR-511-3p or miR-511-3p-mut were obtained from 3 independent biological samples/each. Gene expression profiles of miRNA-overexpressing TAMs were then compared with the gene expression profiles of wild-type TAMs isolated from LLCs grown in nontransplanted C57BL/6 mice; the latter TAMs were subfractioned into MRC1+CD11c(low) or CD11c+MRC1(low) subsets before RNA isolation and analysis. Comparison of gene expression profiles of TAMs revealed that miR-511-3p overexpression tunes down the expression of multiple genes that are classically upregulated in protumoral MRC1+CD11c(low) TAMs. TAMs were isolated from Lewis lung carcinomas grown s.c. in C57BL/6 mice.

Transcriptome sequencing analysis of CSF-1Rhigh TAMs and CSF-1Rlow TAMs in colon adenocarcinoma.

Project description:Tumor-associated macrophages (TAMs) are a major component of the leukocyte and a heterogenous population in tumors. Recent reports have increasingly suggested that manipulating the function of TAMs may serve as a promising therapeutic strategy against advanced tumors. Our present work indicates that CSF-1R+ TAMs are abundantly found in a significant proportion of COAD specimens. Therefore，to determine the role of the CSF-1Rhigh TAMs in COAD, we sorted the CSF-1Rhigh TAMs and the CSF-1R low TAMs from the colon adenocarcinomas for Smart-seq2. We found that CSF-1Rhigh TAM infiltration involved in multiple tumor immune signaling pathways. CSF-1Rhigh TAMs mostly exhibited a immunosuppressive phenotypes, and were associated with enhanced levels of Treg cells. CSF-1R high TAMs promotes COAD progression by modulating tumor immunity environment

The effect of imatinib therapy on tumor associated macrophages (TAMs) in human gastrointestinal stromal tumor (GIST)

Project description:The gene expression profile of TAMs microbead isolated from freshly obtained human GISTs were compared in tumors that were untreated, responding to imatinib (sensitive), or resistant to imatinib (resistant) The Affymetrix Human Genome U133A 2.0 platform was used TAMs were microbead isolated from 12 untreated, 5 sensitive, and 4 resistant tumors. Tumors were obtained freshly from the operating room from consenting patients using an IRB approved protocol. Tumors were digested using collagenase and TAMs isolated using microbead negative selection for KIT, CD3, and CD56 followed by positive selection for CD14.

Transcriptional analysis of forebrain plus optic cup from zebrafish embryos after BMP4 overexpression

Project description:Forebrain and optic cups were microdissected from zebrafish embryos at 21 hours post-fertilization (hpf) after heat-shock at 15 hpf to induce overexpression of BMP in heterozygous tg(hsp70l:bmp4) embryos vs wild type controls.

The effect of imatinib therapy on tumor associated macrophages (TAMs) in murine gastrointestinal stromal tumor (GIST)

Project description:The gene expression profile of TAMs sorted from vehicle control tumors in GIST mice (Sommer et al, PNAS 2003) was compared to TAMs sorted from mice after 2 weeks of imatinib therapy The Affymetrix Mouse Genome 430A 2.0 platform was used Each treatment group had 8 mice. After 2 weeks of treatment, mice were sacrificed and tumors digested with collagenase. TAMs were then FACS sorted and pooled by group. Pooled groups were run in duplicate for the gene expression array.

Expression data from in vitro-induced non-hypoxic tumour associated macrophages (TAMs)

Project description:Active immunotherapy is a promising strategy for anti-angiogenic cancer therapy. Recently, we have reported that a vaccine using human umbilical vein endothelial cells (HUVECs) induced specific anti-endothelial immune responses in the most of immunized patients, and resulted in tumor regression in some patients with recurrent malignant brain tumors, whereas not in colorectal cancer patients. In this study, we hypothesized that non-hypoxic perivascular tumor associated macrophages (TAMs) in colorectal cancer, but not in glioblastoma, might negatively alter the therapeutic efficacy of anti-angiogenic active immunotherapy. To test this hypothesis, we examined global gene expression profiles of non-hypoxic macrophages stimulated in vitro by soluble factors released from tumor cells of human glioblastoma U-87MG (‘brain TAMs’) or colorectal adenocarcinoma HT-29 (‘colon TAMs’). Murine non-hypoxic TAMs were induced in vitro by incubation with soluble factors released from human cancer cell lines U-87MG ('brain TAMs') or HT-29 ('colon TAMs'), for RNA extraction and subsequent hybridization on Affymetrix microarrays. To evaluate homogeneous macrophage populations at different tumour developmental stages, RNA aliquots of control macrophages and TAMs obtained at five different time-points, i.e. 8h, 16h, 24h, 32h and 40h, were pooled and used for screening of differentially expressed genes. The experiments for TAMs as well as for control unstimulated macrophages were performed in triplicates.
