Lamin A/C is phosphorylated at serine 22 upon HS. (A) Western blot (WB) analysis of lamin A/C (LAC), phospho-serine 22 lamin A/C (pSer22 LAC), phospho-serine 392 lamin A/C (pSer392 LAC) and heat shock <t>factor</t> <t>1</t> (HSF1) after 1–4 h heat shock (HS) at 42°C, and 3 h and 24 h recovery at 37°C in HeLa cells and primary human and mouse fibroblasts. Whole D. melanogaster flies were heat-shocked for 30 min at 37°C and left to recover for 3 or 7 h at 22°C. The average numerical values of signal intensities relative to loading control (GAPDH or actin) from individual experiments are shown below each blot. pSer22 and pSer392 lamin A/C levels were normalized to GAPDH and lamin A/C. (B) Quantification of pSer22 lamin A/C WB intensities upon HS and recovery in HeLa cells ( n =5), human fibroblasts, mouse fibroblasts and D. melanogaster fruit flies ( n =4). Plots show mean±s.d. and the individual datapoints. The shapes of the datapoints indicate each individual replicate. * P <0.05; ** P <0.01 (Mann–Whitney test). (C) Heat shock experiment with synchronized HeLa cells. Aphidicolin was used to synchronize cells to G1/S phase and nocodazole to synchronize cells to mitosis (positive control). GAPDH was used as a loading control ( n =2). (D) HeLa cells, human and mouse fibroblasts were cultured either in normal culture conditions or exposed to 4 h HS at 42°C, fixed and stained for lamin A/C (green), pSer22 lamin A/C (magenta) and DAPI (gray). The narrow panels show the orthogonal views of the yz -plane. Scale bars: 10 μm.
