RITA, the RBP‐J interacting and tubulin‐associated protein, has been reported to be related to tumor development, but the underlying mechanisms are not understood. Since RITA interacts with tubulin and coats microtubules of the cytoskeleton, we hypothesized that it is involved in cell motility. We show here that depletion of RITA reduces cell migration and invasion of diverse cancer cell lines and mouse embryonic fibroblasts. Cells depleted of RITA display stable focal adhesions (FA) with elevated active integrin, phosphorylated focal adhesion kinase, and paxillin. This is accompanied by enlarged size and disturbed turnover of FA. These cells also demonstrate increased polymerized tubulin. Interestingly, RITA is precipitated with the lipoma‐preferred partner (LPP), which is critical in actin cytoskeleton remodeling and cell migration. Suppression of RITA results in reduced LPP and α‐actinin at FA leading to compromised focal adhesion turnover and actin dynamics. This study identifies RITA as a novel crucial player in cell migration and invasion by affecting the turnover of FA through its interference with the dynamics of actin filaments and microtubules. Its deregulation may contribute to malignant progression.

Background Psoriasis is a frequent chronic inflammatory cytokine‐mediated skin disease and was identified to be an independent risk factor for the occurrence of myocardial infarction (MI). However, data about the impact of psoriasis on mortality and other in‐hospital adverse events in the setting of MI are sparse and inconsistent. Methods and Results The nationwide German inpatient sample of the years 2005 to 2016 was used for statistical analysis. Hospitalized patients with MI were stratified for the presence of psoriasis and the impact of psoriasis on in‐hospital events was investigated. Overall, 3 307 703 patients with MI (37.6% females, 56.8% aged ≥70 years) were treated in Germany (2005–2016); among them 9028 (0.3%) were diagnosed with psoriasis. Patients with MI with psoriasis were significantly younger (68.0 [58.0–76.0] versus 73.0 [62.0–81.0] years; P
