Project description:Here we addressed the genome-wide DNA binding profile of Helios transcription factor in early hematopoietic progenitor cells. We reported Helios DNA target sites by performing Chromatin Immuno-Precipitation (ChIP) assay on genomic DNA from the early hematopoietic progenitor cells line HPC7.

Project description:Given the potential role of the helios transcription factor in postnatal outer hair cell gene regulation indicated by our RiboTag translatome analyses, our next goal was to identify and validate genes that are regulated by helios in outer hair cells by performing RNA-seq on P8 cello mutant animals compared to wild-type littermates.

Project description:Lenalidomide achieves its therapeutic efficacy by recruiting and removing proteins of therapeutic interest through the E3 ligase substrate adapter cereblon. Here, we report the rational design and characterization of 81 cereblon ligands for their ability to degrade the transcription factor Helios (IKZF2) and casein kinase 1 alpha (CK1α) in acute myeloid leukemia MOLM-13 cells. Using a structure-based approach, we identified a key naphthamide scaffold that depleted both intended targets. Structure-activity relationship studies for degradation of the desired targets over other targets (IKZF1, GSPT1) afforded an initial lead compound, termed DEG-35. A subsequent scaffold replacement campaign informed by degradation profiles against a panel of substrates identified DEG-77, which selectively degrades IKZF2 and CK1α, and possesses suitable pharmacokinetic properties, solubility, and selectivity for in vivo studies. Finally, we show that DEG-77 has antiproliferative activity in diffuse large B cell lymphoma (DLBCL) cell line OCI-LY3 and ovarian cancer cell line A2780, indicating that these dual degraders and their targets may have efficacy against additional cancer types.

Project description:Estrogen Receptor alpha (ERα) is a key driver of most breast cancers, and it is the target of endocrine therapies used in the clinic to treat women with ERα positive (ER+) breast cancer. The two methods ChIP-seq (chromatin immunoprecipitation coupled with deep sequencing) and RIME (Rapid Immunoprecipitation of Endogenous Proteins) have greatly improved our understanding of ERα function during breast cancer progression and in response to anti-estrogens. A critical component of both ChIP-seq and RIME protocols is the antibody that is used to pull down the bait protein. To date, most of the ChIP-seq and RIME experiments for the study of ERα have been performed using the sc-543 antibody from Santa Cruz Biotechnology. However, this antibody has been discontinued, thereby severely impacting the study of ERα in normal physiology as well as diseases such as breast cancer and ovarian cancer. Here, we compare the sc-543 antibody with other commercially available antibodies, and we show that 06-935 (EMD Millipore) and ab3575 (Abcam) antibodies can successfully replace the sc-543 antibody for ChIP-seq and RIME experiments.

Project description:The maintenance of immune homeostasis requires regulatory T cells (Tregs). Given their intrinsic self-reactivity, Tregs must stably maintain a suppressive phenotype to avoid autoimmunity. We report that impaired expression of the transcription factor (TF) Helios by FoxP3+ CD4 and Qa-1-restricted CD8 Tregs results in defective regulatory activity and autoimmunity in mice. Helios-deficient Treg develop an unstable phenotype during inflammatory responses characterized by reduced FoxP3 expression and increased effector cytokine expression secondary to diminished activation of the STAT5 pathway. CD8 Treg also require Helios-dependent STAT5 activation for survival and to prevent terminal T cell differentiation. Definition of Helios as a key transcription factor that stabilizes regulatory T-cells in the face of inflammatory responses provides a genetic explanation for a core property of regulatory T-cells.

Project description:This experiment aimed to determine Helios contribution in chromatin accessibility in hematopoietic stem and progenitor cells. Thus, we examined the change in chromatin accessibility in purified hematopoietic stem cells (LSK, Lin-Sca1+ckit+) from 10 weeks old WT and Helios deficient mice using the ATAC-seq approach. We found that Helios null LSK an affected Open Chromatin Region (OCR) landscape, overall in the proximity of genes regulating platelets functions.

Project description:IKZF2 is an important nuclear matrix protein and plays a pivotal role in T cell development and differentiation, while its expression and function in Cutaneous T cell lymphoma (CTCL) remain ambiguous. Our study aimed to investigate the expression pattern, biological function of IKZF2 in a large clinical cohort. IKZF2 is specifically over-expressed in malignant T cells with MF tumor-stage. In order to explore the function of IKZF2 in the pathogenesis of CTCL, transcriptome sequencing was performed among Hut78 cells transfected with shRNAs targeting IKZF2 (shIKZF2) and scrambled shRNA(sh0) to investigate genes regulated by IKZF2 in CTCL cells .
