Figure 7Proposed working model of CARM1-USP7-LSD1 axis involved in breast cancer metastasis. CARM1 methylates LSD1, which promotes its binding with and de-ubiquitylation by USP7, leading to LSD1 stabilization. The stabilization of LSD1 enhances the demethylation of H3K4me2 at E-cadherin promoter and H3K9me2 at vimentin promoter, resulting in repression of E-cadherin and activation of vimentin gene expression, respectively, which consequently promotes breast cancer metastasis.

CA VII and CA II similarly enhance GABAAR-mediated depolarization in CA1 pyramidal neurons.Figure 3Excitatory GABAergic response in WT, but not in CAVII KO neurons. Picrotoxin blocked the biphasic response (PiTX 90 μM; n=3/genotype). The mean initial slope of the depolarizing shift was faster in WT than in CAVII KO (13.53±1.27 versus 6.39±0.96 mV/s, P<0.001, Student's t-test). The resting membrane potential of WT and CAVII KO neurons did not differ (−71.0±1.1 versus −72.3±1.4 mV, respectively; n=15 neurons for both genotypes, P=0.47, Student's t-test). *P<0.05, **P<0.01 and ***P<0.001. Error bars denote s.e.m. and n is the number of slices (C) or cells tested (one cell per slice) (A, B and D) Microinjection of GABA (5 mM for 100 ms, sr/slm border in the presence of CGP55845/TTX, arrowheads) induced a pronounced depolarization in WT neurons (black) that was abolished in the absence of CO2/HCO3− (grey). The depolarization was smaller in CA VII KO (red).

In the presence of AP5/CNQX/CGP55845, microinjection of GABA (5 mM, sr/slm border) triggered SR 95531-sensitive field potential spikes in WT slices already upon 8-ms injection, while even 16-ms injection evoked hardly any spikes in CAVII KO (left). Mean number of spikes was plotted against GABA puff duration in P12-16 WT and CAVII KO (P<0.01 and P<0.001, Student's t-test; right). *P<0.05, **P<0.01 and ***P<0.001.
