Expression of identical X and Y chromosome genes differentially expressed in males following ischemic stroke. RNA expression (log2-transformed intensity values) is shown on the Y axis for CSF2RA (A), VAMP7 (B), SPR3(C) and DHRSX (D). Control males and male patients at different time points following ischemic stroke (≤ 3h, 5h, 24h) are shown on the X axis, each circle represents a single patient. Note: * = significantly changed following stroke compared to control (C) (p <0.05, FC>∣1.2∣).
