A SNARE protein Syntaxin 17 captures CFTR to potentiate autophagosomal clearance under stress FASEB J. (IF 4.966) Pub Date : 2020-11-15 Kavisha Arora; Pramodha Liyanage; Qing Zhong; Anjaparavanda P. Naren
Autophagy, a cellular stress response to starvation and bacterial infection, is executed by double‐membrane‐bound organelles called autophagosomes. Autophagosomes transfer cytosolic material to acidified lysosomes for degradation following soluble N‐ethylmaleimide‐sensitive factor attachment receptor (SNARE)‐dependent fusion processes. Many of the autophagy‐related disorders stem from defective end‐step

(IF 4.966) Pub Date : 2020-12-24 Yanwen Mao; Xiaohuan Zhang; Wei Peng; Huiming Liu; Xingchen Zhou; Luqun Liang; Jiayi Xiang; Huifang Zhang; Dan Wang; Lingling Liu; Yuxia Zhou; Fan Zhang; Ying Xiao; Mingjun Shi; Yuanyuan Wang; Bing Guo
Etoposide‐induced 2.4 (EI24) exerts tumor suppressor activity through participating in cell apoptosis, autophagy, and inflammation. However, its role in renal diseases has not been elucidated. This study showed that the EI24 level decreased gradually in the kidneys of mice with unilateral ureteral obstruction (UUO) and in another fibrosis model induced by diabetic kidney disease. The overexpression

The tumor suppressor LATS2 reduces v‐Src‐induced membrane blebs in a kinase activity‐independent manner FASEB J. (IF 4.966) Pub Date : 2020-12-24 Masayoshi Ikeuchi; Ryuzaburo Yuki; Youhei Saito; Yuji Nakayama
When cells with excess DNA, such as tetraploid cells, undergo cell division, it can contribute to cellular transformation via asymmetrical chromosome segregation‐generated genetic diversity. Cell cycle progression of tetraploid cells is suppressed by large tumor suppressor 2 (LATS2) kinase‐induced inhibitory phosphorylation of the transcriptional coactivator Yes‐associated protein (YAP). We recently

Stimulation of endogenous pulsatile growth hormone secretion by activation of growth hormone secretagogue receptor reduces the fat accumulation and improves the insulin sensitivity in obese mice FASEB J. (IF 4.966) Pub Date : 2020-12-24 Zhengxiang Huang; Xuehan Lu; Lili Huang; Chunhong Zhang; Johannes D. Veldhuis; Michael A. Cowley; Chen Chen
Obese individuals often show low growth hormone (GH) secretion, which leads to reduced lipid mobilization and further fat accumulation. Pharmacological approaches to increase GH levels in obese individuals by GH injection or GH‐releasing hormone receptor agonist showed promising effects on fat reduction. However, side effects on glucose metabolism and the heavy costs on making large peptides hindered

Deletion of delta‐like 1 homologue accelerates renal inflammation by modulating the Th17 immune response FASEB J. (IF 4.966) Pub Date : 2020-12-24 Laura Marquez‐Exposito; Raul R. Rodrigues‐Diez; Sandra Rayego‐Mateos; Marta Fierro‐Fernandez; Raquel Rodrigues‐Diez; Macarena Orejudo; Laura Santos‐Sanchez; Eva Maria Blanco; Jorge Laborda; Sergio Mezzano; Santiago Lamas; Carolina Lavoz; Marta Ruiz‐Ortega
Preclinical studies have demonstrated that activation of the NOTCH pathway plays a key role in the pathogenesis of kidney damage. There is currently no information on the role of the Delta‐like homologue 1 (DLK1), a NOTCH inhibitor, in the regulation of renal damage. Here, we investigated the contribution of DLK1 to experimental renal damage and the underlying molecular mechanisms. Using a Dlk1‐null

27‐Hydroxycholesterol regulates human SLC22A12 gene expression through estrogen receptor action FASEB J. (IF 4.966) Pub Date : 2020-12-23 Masaya Matsubayashi; Yoshihiko M.

The excretion and reabsorption of uric acid both to and from urine are tightly regulated by uric acid transporters. Metabolic syndrome conditions, such as obesity, hypercholesterolemia, and insulin resistance, are believed to regulate the expression of uric acid transporters and decrease the excretion of uric acid. However, the mechanisms driving cholesterol impacts on uric acid transporters have been

The duration of food withdrawal affects the intestinal structure, nutrients absorption, and utilization in broiler chicken FASEB J. (IF 4.966) Pub Date : 2020-11-15 Youli Wang; Yuqin Wu; Jing Chen; Xiaorui Guo; Lei Yan; Yuming Guo; Bo Wang; Jianmin Yuan
Food withdrawal is usually used for accurate feed metabolizable energy (ME) assessment in poultry, but its effects on intestinal structure and the absorption of nutrients are unclear. In this study, broilers were fed ad libitum (CT) or withdrew food for 12 (FH12), 24 (FH24), 36 (FH36), or 48 hours (FH48). We showed that food withdrawal increased the energy assimilation when compared with the CT. Food

Thrombospondin 1‐induced exosomal proteins attenuate hypoxia‐induced paraptosis in corneal epithelial cells and promote wound healing FASEB J. (IF 4.966) Pub Date : 2020-12-20 Yu‐Hung Lai; Po‐Yen Lee; Chi‐Yu Lu; Yu‐Ru Liu; Shu‐Chi Wang; Ching‐Chih Liu; Yo‐Chen Chang; Yung‐Hsiang Chen; Chia‐Cheng Su; Chia‐Yang Li; Po‐Len Liu
Thrombospondin‐1 (TSP1) is involved in corneal wound healing caused by chemical injury. Herein, we examined the effects of TSP1 on hypoxia‐induced damages and wound‐healing activity in human corneal epithelial (HCE) cells. Exosomal protein expression was determined using liquid chromatography‐tandem mass spectrometry, and HCE cell migration and motility were examined through wound‐healing assay and

From structural resilience to cell specification — Intermediate filaments as regulators of cell fate FASEB J. (IF 4.966) Pub Date : 2020-11-17 Marika Sjöqvist; Daniel Antfolk; Freddy Suarez‐Rodriguez; Cecilia Sahlgren
During the last decades intermediate filaments (IFs) have emerged as important regulators of cellular signaling events, ascribing IFs with functions beyond the structural support they provide. The organ and developmental stage‐specific expression of IFs regulate cell differentiation within developing or remodeling tissues. Lack of IFs causes perturbed stem cell differentiation in vasculature, intestine

Long noncoding RNA H19 acts as a miR‐29b sponge to promote wound healing in diabetic foot ulcer FASEB J. (IF 4.966) Pub Date : 2020-11-10 Bo Li; Yue Zhou; Jing Chen; Tingting Wang; Zhijuan Li; Yili Fu; Aixia Zhai; Changlong Bi
Aberrant expression of long noncoding RNA (lncRNA) H19 and microRNA (miR)‐29b has been implicated in the complications of diabetes mellitus (DM). As a common and important complication of DM, diabetic foot ulcer (DFU) is characterized by high incidence and poor prognosis. Herein, we explored the role of lncRNA H19 in wound healing of DFU. Differentially expressed DM‐related lncRNAs were initially screened

SHP2 regulates the development of intestinal epithelium by modifying OSTERIX+ crypt stem cell self‐renewal and proliferation FASEB J. (IF 4.966) Pub Date : 2020-11-09 Lijun Wang; Douglas C. Moore; Jiahui Huang; Yuhong Wang; Hu Zhao; Jerry D‐H Yue; Cynthia L. Jackson; Peter J. Quesenberry; Weibiao Cao; Wentian Yang
The protein tyrosine phosphatase SHP2, encoded by PTPN11, is ubiquitously expressed and essential for the development and/or maintenance of multiple tissues and organs. SHP2 is involved in gastrointestinal (GI) epithelium development and homeostasis, but the underlying mechanisms remain elusive. While studying SHP2’s role in skeletal development, we made osteoblast‐specific SHP2 deficient mice using

LncRNA‐MAP3K4 regulates vascular inflammation through the p38 MAPK signaling pathway and cis‐modulation of MAP3K4 FASEB J. (IF 4.966) Pub Date : 2020-11-12 Haoyang Zhou; Viorel Simion; Jacob B. Pierce; Stefan Haemmig; Alex F. Chen; Mark W. Feinberg
Chronic vascular inflammation plays a key role in the pathogenesis of atherosclerosis. Long non‐coding RNAs (lncRNAs) have emerged as essential inflammation regulators. We identify a novel lncRNA termed lncRNA‐MAP3K4 that is enriched in the vessel wall and regulates vascular inflammation. In the aortic intima, lncRNA‐MAP3K4 expression was reduced by 50% during the progression of atherosclerosis (chronic

Death‐associated protein kinase 1 (DAPK1) controls CD8+ T cell activation, trafficking, and antitumor activity FASEB J. (IF 4.966) Pub Date : 2020-11-13 Zhengping Wei; Qiuyang Du; Pingfei Li; Huicheng Liu; Minghui Xia; Yufei Chen; Guoyu Bi; Zhao‐Hui Tang; Xiang Cheng; Youming Lu; Ran He; Arian Laurence; Jing Wang; Liu Huang; Huabin Li; Xiang‐Ping Yang
Appropriate migration of cytotoxic T effector cells into the tumors is crucial for their antitumor function. Despite the controversial role of PI3K‐Akt in CD8+ T cell mTORC1 activation, a link between Akt‐mTORC1 signaling and CD8+ trafficking has been demonstrated. We have recently discovered that TCR‐induced calcineurin activates DAPK1, which interacts with TSC2 via its death domain and phosphorylates
