    Cell Signaling Technology Inc mouse anti phospho ser139 histone γh2ax antibody
    Dose-regime and efficacy studies of Pt(IV)-M13 reveal DNA-damage effects on GBM tumors. a) Percentage of weight variation of naïve nude mice administered after platinum compound tail-vein injection at the indicated concentrations. Black arrows indicate days of injection (d1, d4, d9, d13, d17, d19). Mean and standard deviation are shown, n = 5 animals per group. b) Average clinical score from study shown in a). Mice were monitored every 2 days for symptomatic changes. Symptoms were classified from no symptoms (0), visible (2), to fatal (4). Eye redness, eye twitching and weight loss were the most visible effects. c) Efficacy study of Pt(IV)-M13 (5 mg/kg, 0.3 mM) compared to cisplatin MTD (5 mg/kg, 3 mM). d) Immunostaining of ϒH2AX <t>(Ser139)</t> using anti-rabbit Alexa Fluor 647, and nuclei with Hoechst 33342.

    Cross talk with H2AK119ub1 drives H3K27me3 restoration (A) Illustration of the questions addressed. Does H2AK119ub1 stimulate H3K27me3 restoration on the lagging strand? Does H3K27me3 increase H2AK119ub1 deposition on the leading strand? (B) Experimental outline to assess H2AK119ub1-dependence of H3K27me3. AID-RING1B RING1A −/− MCM2-2A cells were treated for 2 h with Auxin or DMSO prior to 10 min EdU labeling and indicated chase time course. (C) Asymmetry plot showing restoration of H3K27me3 asymmetry across H3K27me3 peaks in DMSO and Auxin-treated cells over time. Positive values indicate leading strand bias. Negative values indicate bias toward lagging strand. (D) Asymmetry plot showing restoration of H3K27me3 asymmetry stratified by H2AK119ub1 co-occupancy in Auxin-treated cells over time. (E) JARID2 occupancy across JARID2 peaks on nascent chromatin in untreated and Auxin-treated cells. RRPM scale. (F) Average SCAR-seq profile of JARID2 in untreated or Auxin-treated cells.

(C, D, and G–I) Statistics by unpaired Wilcoxon test. Data are represented as average of three replicates. (J) Model. (Left) Recycling of H2A-H2B at replication forks transmits modifications on parental H2A-H2B to nascent chromatin. Parental H2A-H2B dimers are recycled to both daughter strands independent of H3-H4 tetramers through a pathway involving POLA1 on the lagging strand. Upon reincorporation on daughter strands, parental-modified H2A-H2B can form nucleosomes with new and parental H3-H4 tetramers and new H2A-H2B dimers. Fast restoration kinetics of H2A-H2B modification together with intra- and inter-nucleosomal PTM cross talk then contribute to establishment of modifications on new H3-H4 and H2A-H2B and maintenance of chromatin states across replication. (Right) We propose that recycled parental H2A-H2B PTMs guide the restoration of newly deposited H3-H4 and H2A-H2B in nascent chromatin. Vice versa, stable H3-H4 PTMs reinforce H2A-H2B modifications in mature chromatin responding to dynamic exchange of H2A-H2B. Replisome components involved in histone recycling are colored in blue for H3-H4 and yellow for H2A-H2B.
