Abstract
Oxidized low density lipoprotein (oxLDL)-induced endothelial oxidative damage promotes the development of atherosclerosis. Caveolae play an essential role in maintaining the survival and function of vascular endothelial cell (VEC). It is reported that the long coiled-coil protein NECC2 is localized in caveolae and is associated with neural cell differentiation and adipocyte formation, but its role in VECs needs to be clarified. Our results showed NECC2 expression increased in the endothelium of plaque-loaded aortas and oxLDL-treated HUVECs. Down-regulation of NECC2 by NECC2 siRNA or compound YF-307 significantly inhibited oxLDL-induced VEC apoptosis and the adhesion factors expression. Remarkably, inhibition of NECC2 expression in the endothelium of apoE-/- mice by adeno-associated virus (AAV)-carrying NECC2 shRNA or compound YF-307 alleviated endothelium injury and restricted atherosclerosis development. The immunoprecipitation results confirmed that NECC2 interacted with Tyk2 and caveolin-1(Cav-1) in VECs, and NECC2 further promoted the phosphorylation of Cav-1 at Tyr14 b y activating Tyk2 phosphorylation. On the other hand, inhibiting NECC2 levels suppressed oxLDL-induced phosphorylation of Cav-1, uptake of oxLDL by VECs, accumulation of intracellular reactive oxygen species and activation of NF-κB. Our findings suggest that NECC2 may contribute to oxLDL-induced VEC injury and atherosclerosis via modulating Cav-1 phosphorylation through Tyk2. This work provides a new concept and drug target for treating atherosclerosis.

Tyrosine kinase nonreceptor 1 (TNK1) knockdown ameliorates hemorrhage shock-induced kidney injury via inhibiting macrophage M1 polarization. 3 Biotech 2021; 11:501. [PMID: 34881164 DOI: 10.1007/s13205-021-03042-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2021] [Accepted: 10/29/2021] [Indexed: 12/20/2022] Open
Abstract
Hemorrhage shock (HS) is a major threat to patients with trauma and spontaneous bleeding, resulting in multi-organ failure including the kidney. Tyrosine kinase nonreceptor 1 (TNK1) has been shown to be upregulated in the kidney of experimental HS and patients with severe trauma. The study aims to investigate the role of TNK1 and the underlying mechanism in HS-induced kidney injury. A model of HS was established with femoral artery bloodletting, followed by resuscitation in Sprague-Dawley rats. Renal expression of TNK1 was abnormally induced by HS in rats. Knockdown of TNK1 alleviated HS-induced cell apoptosis and the level of proinflammatory cytokines (TNF-α, IL-6 and IL-1β) in the kidney. The expression of M1 macrophage markers (CD86 and iNOS) and the activation of STAT1 were inhibited by TNK1 knockdown in HS rats. In vitro, human monocyte THP-1 cells were treated with 20 ng/mL interferon-gamma plus 100 ng/mL lipopolysaccharide to induce M1 polarization. TNK1 knockdown exerted inhibitory effect on macrophage M1 polarization, M1-type inflammatory cytokine production and STAT1 activation in THP-1 cells. In conclusion, downregulation of TNK1 alleviates HS-induced kidney injury by suppressing macrophage M1 polarization, inflammation and kidney cell apoptosis, in which the deactivation of STAT1 signaling may be involved.

Abstract
Activated Cdc42-associated kinase 1 (ACK1/TNK2) is a nonreceptor tyrosine kinase with a unique structure. It not only can act as an activated transmembrane effector of receptor tyrosine kinases (RTKs) to transmit various RTK signals but also can play a corresponding role in epigenetic regulation. A number of studies have shown that ACK1 is a carcinogenic factor. Blockage of ACK1 has been proven to be able to inhibit cancer cell survival, proliferation, migration, and radiation resistance. Thus, ACK1 is a promising potential antitumor target. To date, despite many efforts to develop ACK1 inhibitors, no specific small molecule inhibitors have entered clinical trials. This Perspective provides an overview of the structural features, biological functions, and association with diseases of ACK1 and in vitro and in vivo activities, selectivity, and therapeutic potential of small molecule ACK1 inhibitors with different chemotypes.
