Project description:In this study we examined the effects of loss of the MYST histone acetyltransferase TIP60 (KAT5) in mouse embryonic fibroblasts (MEFs), human embryonic kidney cells 293 (HEK293), and human osteosarcoma cells (U2OS) on cell proliferation, BrdU incorporation, cell cycle progression, apoptotic and other forms of cell death, DNA damage, histone acetylation at specific lysine residues and RNA expression levels. This dataset relates to MEFs. To assess the effects of loss of TIP60 on RNA levels, RNA-seq was performed on MEFs, where the TIP60 gene was deleted using Cre/loxP technology. Nuclear translocation was induced with 4-OH-tamoxifen treatment for 3 and 5 days to induce TIP60 gene deletion in the samples also containing the loxP sited in the Tip60 locus.

This dataset relates to U2OS cells. To assess the effects of loss of TIP60 on RNA levels, RNA-seq was performed on U2OS cells, where the TIP60 gene was mutated by CRISPR/Cas9 technology using single guide RNA #1 (g1/C9), single guide RNA #2 (g2/C9), or guide-only controls (g1 or g2). The expression of the guide RNA was induced with doxycycline treatment for 4 days to induce TIP60 gene mutation in the samples also expressing the Cas9 enzyme.

Project description:The Tip60 (also known as Kat5) lysine acetyltransferase functions broadly as a transcriptional co-activator that acetylates histones. In contrast, Tip60 functions in embryonic stem cells (ESCs) both to silence genes that promote differentiation and to activate genes required for proliferation. The mechanism by which Tip60 functions as a repressor is unknown. Here we show that the class II histone deacetylase Hdac6 co-purifies with Tip60-p400 complex from ESCs and is necessary for complete silencing of most differentiation genes targeted by Tip60. In contrast to differentiated cells, where Hdac6 is mainly cytoplasmic and does not interact with Tip60, Hdac6 is largely nuclear in ESCs and neural stem cells (NSCs) and interacts with Tip60-p400 in both cell types. Hdac6 is enriched at promoters bound by Tip60-p400 in ESCs, but while Tip60 binds on both sides of transcription start sites (TSSs), Hdac6 binding overlaps with only the downstream Tip60 peak. Surprisingly, Hdac6 does not deacetylate histones at these sites, but rather is required for Tip60 binding. These data suggest that nuclear exclusion of Hdac6 during differentiation plays a major role in modulation of Tip60-p400 function. We determined the genome-wide localization of Tip60 and Hdac6 in mouse ES cells, and examined genomic binding profiles of Tip60 and Hdac6 upon indicated knockdown by ChIP-seq. We examined genomic binding profiles of p400 upon indicated knockdown by ChIP-seq.

Project description:Genome-wide mapping of TIP60 complex subunits in K562 cells. The objectives of this study are to describe TIP60 genome wide localization, confirm MBTD1 co-localization with already known unique subunits and observe the impact of MBTD1 on TIP60 complex targeting to chromatin. The TIP60 acetyltransferase complex is a key regulator of genome expression and stability. Here, we identified MBTD1 as a new stable subunit of the complex and revealed interesting insights about TIP60 function during the repair of DNA double strand breaks. MBTD1 binds H4K20me1/2, helping TIP60 association to specific promoters but also the DNA repair process by homologous recombination. While pro-end joining factor 53BP1 engages chromatin through simultaneous binding of H4K20me2 and H2AK15ub, TIP60 regulates the resolution of 53BP1 foci after DNA damage through a related bivalent mechanism. MBTD1 competes with 53BP1 for the H4K20me2 mark, affecting its retention at the break cooperatively with H4 acetylation by TIP60. In addition, we show that H2AK15ub deposition by RNF168 inhibits chromatin acetylation by TIP60, whereas H2AK15 can also be acetylated by TIP60 in vivo, therefore blocking its ubiquitylation. Altogether, these results uncover an intricate mechanism orchestrated by the TIP60 complex to regulate 53BP1-dependent repair pathway selection, through incompatible bivalent binding/action on chromatin.

Project description:Histone modifications play crucial roles in transcriptional activation, and aberrant epigenetic changes are associated with oncogenesis. Lysine (K) acetyltransferases 5 (TIP60, also known as KAT5) is reportedly implicated in cancer development, although its function in lung cancer remains unclear. Here we demonstrate that TIP60 knockdown in non-small cell lung cancer cells decreased tumor cell progression. Furthermore, analysis of a mouse lung cancer model with lung-specific conditional Tip60 knockout revealed suppressed tumor formation relative to controls, but no apparent effects on normal lung homeostasis. RNA-seq and ChIP-seq analyses of inducible TIP60 knockdown H1975 cells relative to controls revealed transglutaminase enzyme (TGM5) as downstream of TIP60. In addition, a candidate TIP60 inhibitor suppressed tumor growth in cell culture and in vivo. Taken together, suppression of TIP60 activity shows tumor-specific efficacy against lung cancer, with no overt effect on normal tissues. Our work suggests that targeting TIP60 could be a promising approach in treating lung cancer.
