The redevelopment of Thomond Park, Limerick
Thomond Park, the historic home of Munster Rugby, has undergone major redevelopment (fig. 1) which will see its capacity rise to 25 756. This paper describes the design and construction of the new stand and terrace structures. Particular emphasis is given to the development of the engineering and architectural concepts , the wind tunnel testing and dynamic analysis undertaken during detailed design, and the fabrication and erection of the two 150m span 'rainbow' trusses
HIRA is enriched in the vicinity of <i>Tnni2</i>/<i>Tnnt3</i>, which is upregulated in conditionally deleted <i>Hira</i> mutants, and binds GAGA rich DNA.

An intergenic region on chromosome 6 was used as a negative control. Data is normalized to the input (= 100) and is representative of 2 independent experiments.

HIRA interacts with WHSC1 and binds to the <i>TTe</i> in the cardiac lineage and heart, and is required for differentiation-associated H3.3 enrichment at this locus.
<p><b>A.</b> 20 E14.5 hearts from WT embryos were isolated, pooled and immunoprecipitated with HIRA Wc15 antibody and immunoblotted with WHSC1. Presence of HIRA in the IP was verified using Wc119 antibody. <b>B.</b> Mouse ESCs (control and <i>Hira</i><sup><i>-/-</i></sup> ES cells) were differentiated towards cardiomyocytes over 15 days in LIF free medium following the hanging drop method, and were subjected to RNA and protein isolation. qRT-PCR of <i>Brachyury (T)</i>, <i>Mesp1 and Nkx2</i>.<i>5</i> over the 15 days are presented and demonstrate sequential expression of the early mesoderm, cardiogenic mesoderm, and cardiac markers respectively. Data are shown as levels of mRNA normalized to <i>Gapdh</i> and are representative of five independent experiments. Errors bars represent the standard deviation of technical triplicates. <b>C.</b> Protein isolated from undifferentiated ESCs and 15 days differentiated control and <i>Hira</i><sup><i>-/-</i></sup> ESCs were immunoprecipitated with anti-HIRA Wc15 antibody and immunoblotted with anti-WHSC1 antibody. The results shown are all from the same western membrane but separated lanes are brought into proximity and separated by dashed bars. GAPDH is used as a control for input. <b>D.</b> HIRA and H3.3 qChIP on differentiating ESCs shows an enrichment of HIRA at the <i>TTe</i> at day 15. H3.3 enrichment at the <i>TTe</i> increases significantly in WT but not in <i>Hira</i> null ESCs following this differentiation. X6 is an intergenic negative control region. Unpaired t-test was used: p<0.05 *, p<0.01 **.</p
