Description
Solid tumors are less oxygenated than normal tissues, and for this reason the cancer cells have developed several molecular mechanisms of adaptation to hypoxic environment. Moreover, his poor oxygenation is a major indicator of an adverse prognosis and leads resistance to standard anticancer treatment. Previous reports from this laboratory showed an involvement of Che-1/AATF (Che-1) in cancer cell survival under stress conditions, and on the basis of these observations, we hypothesized that Che-1 might have a role in the response of cancer cells to hypoxia. Methods: The human colon adenocarcinoma cell line HCT116 depleted or not for Che-1 by siRNA, was subjected to normoxic and hypoxic conditions to perform studies about the role of this protein in metabolic adaptation and cell proliferation. The expression of Che-1 under normoxia or hypoxia was detected using western blot assays; cell metabolism was assessed by NMR spectroscopy and functional assays. Further molecular studies were performed by RNA seq, qRT-PCR and ChIP analysis. Results: In this paper we report that Che-1 expression is required for the adaptation of the cells to hypoxia, playing and important role in metabolic modulation. Indeed, Che-1 depletion impacted on glycolysis by altering the expression of several genes involved in the response to hypoxia by modulating the levels of HIF-1alpha. Conclusions: These data demonstrate a novel player in the regulation of a HIF1alpha in response to hypoxia. We found that the transcriptional down-regulation of a members of E3 ubiquitin ligase family SIAH2 by Che-1, produces a failure in the degradation by the hydroxylase PHD3 with a decrease in HIF-1alpha levels during hypoxia. Overall design: The human colon adenocarcinoma cell line HCT116 depleted or not for Che-1 by siRNA was profiled for mRNA high-troughput sequencing (RNA-seq)

Description
Che-1 is a RNA Polymerase II binding protein involved in the regulation of gene transcription. We have observed that Che-1 depletion induces apoptosis in several cancer cells expressing mutated forms of p53. We used microarrays to investigate classes of genes regulated by Che-1 in one of these cell lines.
Publication Title
Che-1 promotes tumor cell survival by sustaining mutant p53 transcription and inhibiting DNA damage response activation.

Description
The effectiveness of new cancer therapies such as checkpoint blockade and adoptive cell transfer of activated anti-tumor T cells requires overcoming immunosuppressive tumor microenvironments. We found that the activation of tumor-infiltrating myeloid cells to produce local nitric oxide is a prerequisite for adoptively transferred CD8+ cytotoxic T cells to destroy tumors. These myeloid cells are phenotypically similar to Tip-DCs or nitric oxide- and TNF-producing dendritic cells. The nitric oxide-dependent killing was tempered by coincident arginase 1 expression, which competes with iNOS for arginine, the substrate for nitric oxide production. Depletion of immunosuppressive CSF-1R-dependent arginase 1+ myeloid cells enhanced nitric oxide-dependent tumor killing. Tumor killing via iNOS was independent of the microbiota but dependent on the CD40-CD40L pathway and, in part, lymphotoxin alpha. We extended our findings in mice to uncover a strong correlation between iNOS, CD40 and TNF expression and survival in colorectal cancer patients. Our results identify a network of anti-tumor targets to boost the efficacy of cancer immunotherapies.

Description
MEN1 is a tumor suppressor gene loss of which causes lipoma (fatty tumors under the skin) and many other endocrine and non-endocrine tumors. It's target genes in fat cells (adipocytes) are unknown. Gene expression in adipocytes that were in vitro differentiated from mouse embryonic stem cells (mESCs) of Men1-nul l(Men1-KO) and WT mice were compared to assess the expression of genes upon menin loss in adipocytes that could lead to the deveopment of lipoma.
