Project description:Thymocyte selection-associated high mobility group box protein family member 2 (TOX2) is a transcription factor belonging to the TOX family that shares a highly conserved high mobility group DNA binding domain with the other TOX members. While TOX1 has been shown to be an essential regulator of T-cell and natural killer (NK) cell differentiation in mice, little is known about the roles of the other TOX family members in lymphocyte development, particularly in humans. In this study, we found that TOX2 was preferentially expressed in mature human NK cells and was upregulated during in vitro differentiation of NK cells from human umbilical cord blood (UCB)M-bM-^@M-^Sderived CD34+ cells. Gene silencing of TOX2 intrinsically hindered the transition between early developmental stages of NK cells, while overexpression of TOX2 enhanced the development of mature NK cells from UCB CD34+ cells. We subsequently found that TOX2 was independent of ETS-1 but could directly upregulate the transcription of TBX21 (encoding T-BET). Overexpression of T-BET rescued the TOX2 knockdown phenotypes. Given the essential function of T-BET in NK cell differentiation, TOX2 therefore plays a crucial role in controlling normal NK cell development by acting upstream of TBX21 transcriptional regulation. survey of NK cells over time

Project description:RNA-Seq was performed in human natural killer/T Cell Lymphoma cell line NKYS ells treated with TOX2-shRNA1, -shRNA2 or with scrambel shRNA. Total RNA was extracted using RNeasy mini kit (Qiagen). The decreased TOX2 expression was confirmed by RT-PCR. The RNA library construction and RNA-sequencing services were provided by Novogene Singapore.

Project description:T-BET and EOMES are key transcription factors in the development of mature Natural Killer (NK) cells in mice. However, the role of these transcription factors during human NK cell development is less well understood. Therefore, we overexpressed T-BET or EOMES in human umbilical cord blood-derived HPC and cultured them in vitro in an NK cell differentiation model. To evaluate the effect of early overexpression of T-BET and EOMES in HPC, transcriptome profiling was performed on T-BET and EOMES overexpressing HPC and compared to control transduced HPC by RNA sequencing on day 0 of culture.

Project description:T-BET and EOMES are key transcription factors in the development of mature Natural Killer (NK) cells in mice. However, the role of these transcription factors during human NK cell development is less well understood. Therefore, we overexpressed T-BET or EOMES in human umbilical cord blood-derived HPC and cultured them in vitro in an NK cell differentiation model. To evaluate the effect of early overexpression of T-BET and EOMES in HPC, the chromatin landscape was uncovered using assay for transposase-accessible chromatin (ATAC) sequencing. In this way, the regulatory effect of T-BET and EOMES overexpression on the epigenome of HPC was evaluated.
