NLRC5 is an important regulator in innate immune responses. However, the ability of NLRC5 to inhibit NF-κB activation is controversial in different cell types. How dynamic modification of NLRC5 shapes NF-κB signaling remains unknown. We demonstrated that NLRC5 undergoes robust ubiquitination by TRAF2/6 after lipopolysaccharide treatment, which leads to(More)
Cyclic GMP-AMP synthase (cGAS) is an essential DNA virus sensor that triggers type I interferon (IFN) signaling by producing cGAMP to initiate antiviral immunity. However, post-translational regulation of cGAS remains largely unknown. We report that K48-linked ubiquitination of cGAS is a recognition signal for p62-depdendent selective autophagic(More)
Panicle architecture is closely related to yield formation. The qPE9-1 gene has been proved to be widely used in high-yield rice cultivar developments, conferring erect panicle character in japonica rice. Recently, qPE9-1 has been successfully cloned; however, the genetic effect on grain yield per plant of the erect panicle allele qPE9-1 is controversial(More)
The Wx gene encoding granule-bound starch synthase is responsible for the biosynthesis of amylose, which plays an important role in determining rice eating and cooking quality. However, the functional evaluation of different Wx alleles remains unclear. In the present study, a set of near-isogenic lines (NILs) carrying four different Wx alleles—Wx a , Wx b ,(More)
Grasses display highly diversified inflorescence architectures that differ in the arrangement of spikelets and flowers and determine cereal yields. However, the molecular basis underlying grass inflorescence morphogenesis remains largely unknown. Here we investigate the role of a functionally diversified SEPALLATA MADS-box transcription factor, OsMADS34, in(More)
Background: Increasing evidence from recent studies has revealed the association of CA125 with the diagnosis of pancreatic cancer, but inconsistent findings have been reported. We aimed to evaluate the diagnostic value of a serum CA125-based diagnostic panel in predicting malignant pancreatic cancer. Materials and Methods: We searched EMBASE, MEDLINE and(More)
Interleukin-1β (IL-1β) secretion downstream of Toll-like receptor (TLR) activation is tightly controlled at the transcriptional and post-translational levels. NLRP3 inflammasome is involved in the maturation of pro-IL-1β, with NLRP3 expression identified as the limiting factor for inflammasome activation. Previously, we had demonstrated that the zinc-finger(More)
BACKGROUND Carcinoembryonic antigen (CEA) is one of the most widely used tumor markers and is increased in 30%-60% of patients with pancreatic cancer. Although carbohydrate antigen 19-9 (CA19-9) is the most important serum biomarker in pancreatic cancer, the diagnostic and prognostic value of CEA is gradually being recognized. MATERIALS AND METHODS The(More)
Pain management after total knee arthroplasty (TKA) remains among the most important challenges for patients with TKA. Intra-articular local anesthetic has been shown to reduce postoperative pain following TKA. However, studies report conflicting results. This meta-analysis evaluated the efficacy and safety of single-dose intra-articular local anesthetics(More)
N-myc downstream-regulated gene 1 (NDRG1) is known as tumor/metastasis suppressor in a variety of cancers including pancreas, being involved in angiogenesis, cancer growth and metastasis. However, the precise molecular mechanism how NDRG1 exerts its inhibitory function in pancreatic cancer remains unclear. In this investigation, we demonstrated that K-Ras(More)
