Aquaporin‐3 and aquaporin‐5 impact the development of pancreatic ductal adenocarcinoma spheroids

open access: yesFEBS Open Bio, EarlyView.
Schematic representation of the role of aquaporin‐3 (AQP3) and aquaporin‐5 (AQP5) in pancreatic ductal adenocarcinoma (PDAC). Both proteins are upregulated in PDAC and are associated with tumor progression and metastatic potential. Silencing AQP3 or AQP5 in PDAC spheroids results in decreased diameter, area, and overall growth, underscoring their key ...

Research Progress on Reference Materials for in situ Elemental Analysis by Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry

open access: yesYankuang ceshi, 2015
Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry (LA-ICP-MS) is currently an important microanalysis technique in the geoscience field. Development of related reference materials is a key for this technique. In this paper, the types, elemental

Unbiasedness of Tests for Homogeneity of Variances

open access: yesThe Annals of Mathematical Statistics, 1971
Abstract : Consider the classical homogeneity of variances model. That is, suppose one has a one way layout, with independent random samples of equal sizes in each column. Assume the samples are from normal populations with unknown means and unknown variances. One wishes to test the hypothesis that all the variances are equal. R. V. Laue (1965) defined

Treatment with KCL‐286, a first‐in‐class retinoic acid receptor‐β (RARβ) agonist, ameliorates neuronal DNA damage and inflammation in a mouse model of Alzheimer's disease

open access: yesFEBS Open Bio, EarlyView.
Repair of neuronal DNA damage in Alzheimer's disease by KCL‐286. (A) Amyloid‐β oligomers and plaques impair neuronal DNA repair pathways, leading to DNA double‐strand breaks and glial activation. (B) KCL‐286 activates RARβ/RXR signalling via retinoic acid response elements (RAREs), associated with increased BRCA1 expression, enhanced DNA repair and ...

Study on the Elemental Fractionation Effect of CGSG Reference Materials and the Related Within-Unit Homogeneity of Major and Trace Elements

open access: yesYankuang ceshi, 2016
Studies on elemental fractionation and homogeneity of CGSG reference materials (CGSG-1, CGSG-2, CGSG-4 and CGSG-5) promote quality assessment and application.

Purification and preparation of Marchantia polymorpha Auxin Response Factor 2 for phase separation studies

open access: yesFEBS Open Bio, EarlyView.
We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...

Tests for Comparing Several Two-Parameter Exponential Distributions Based on Uncensored/Censored Samples

open access: yesJournal of Statistical Theory and Applications (JSTA), 2020
The problems of comparing several exponential distributions based on type II censored samples are considered. Likelihood ratio tests (LRTs) for comparing several location parameters, comparing several scale parameters and for homogeneity of distributions

De novo synthesis of short‐chain aldehydes and hydrocarbons secreted by the brown marmorated stink bug Halyomorpha halys

open access: yesFEBS Open Bio, EarlyView.
The brown marmorated stink bug, Halyomorpha halys, mainly secretes 4‐oxo‐(E)‐2‐hexenal, (E)‐2‐decenal, dodecane and tridecane, a mixture representative of that released by many heteropterans. We demonstrated that H. halys can synthesise these secretory components de novo using dietary glucose.
