Quantitative trait locus mapping of Populus bark features and stem diameter

BMC Plant Biology, 2017
Background Bark plays important roles in photosynthate transport and storage, along with physical and chemical protection. Bark texture varies extensively among species, from smooth to fissured to deeply furrowed, but its genetic control is unknown. This

IRF8 Drives Conventional Type 1 Dendritic Cell Differentiation and CD8+ T Cell Activation to Aggravate Abdominal Aortic Aneurysm Development

Advanced Science, EarlyView.
This study highlights the critical role of IRF8 in the development of AAA. IRF8 activation promotes the differentiation of cDC1s, which in turn recruit and activate CD8+ T cells, contributing to aortic wall degradation. The study identifies the IRF8‐cDC1‐CD8+ T cell axis as a key pathway in AAA progression, offering new potential therapeutic targets to

Structured Input-Output Lasso, with Application to eQTL Mapping, and a Thresholding Algorithm for Fast Estimation [PDF]

arXiv, 2012
We consider the problem of learning a high-dimensional multi-task regression model, under sparsity constraints induced by presence of grouping structures on the input covariates and on the output predictors. This problem is primarily motivated by expression quantitative trait locus (eQTL) mapping, of which the goal is to discover genetic variations in ...

Nanoparticle Delivery of Antisense miR162 Inhibits Invasive Habitat Adaption of Alternanthera Philoxeroides

Advanced Science, EarlyView.
This study demonstrates that the miRNA pathway plays a key role in the invasive growth of Alternanthera philoxeroides in aquatic habitats. Specifically, miR162 is critical for its invasive success, facilitating stem elongation and enhancing survival during submergence.

LMM-Lasso: A Lasso Multi-Marker Mixed Model for Association Mapping with Population Structure Correction [PDF]

arXiv, 2012
Exploring the genetic basis of heritable traits remains one of the central challenges in biomedical research. In simple cases, single polymorphic loci explain a significant fraction of the phenotype variability. However, many traits of interest appear to be subject to multifactorial control by groups of genetic loci instead.

Wnt Inhibition Safeguards Porcine Embryonic Stem Cells From the Acquisition of Extraembryonic Endoderm Cell Fates

Advanced Science, EarlyView.
The study reports that Wnt inhibitors safeguard porcine embryonic stem cells (ESCs) from acquiring the extraembryonic endoderm (XEN) lineage, and further develop an efficient strategy to derive XEN cells from ESCs. The XEN cells from ESCs exhibit similar transcriptome and chromatin accessibility features to XEN cells from embryos and contribute to ...

The neural correlates of retrieval and procedural strategies in mental arithmetic: A functional neuroimaging meta‐analysis

Human Brain Mapping, Volume 44, Issue 1, Page 229-244, January 2023., 2023
The current study used activation likelihood estimation (ALE) to identify, compare, and contrast brain regions that respond to mental arithmetic typically solved using retrieval and procedural strategies at the meta‐analytic level. Collapsing across retrieval and procedural problems, we replicate previous meta‐analytic findings to show that arithmetic ...

Mechanisms and Therapeutic Strategies for Minority Cell‐Induced Paclitaxel Resistance and Tumor Progression Mediated by Mechanical Forces

Advanced Science, EarlyView.
This study provides new perspectives into the interactions between mechanical forces and cellular dynamics within the tumor microenvironment, particularly elucidating how minority Paclitaxel‐resistant cancer cells (MRCs) promote tumor progression and treatment resistance through mechanical forces and also providing effective treatment strategies for ...

Malignant progression of liver cancer progenitors requires lysine acetyltransferase 7–acetylated and cytoplasm‐translocated G protein GαS

Hepatology, EarlyView., 2022
KAT7‐acetylated and cytoplasm‐translocated G‐protein GαS enhances IL‐6 effect and drives HCC progenitor cell progression. Abstract Background and Aims Hepatocarcinogenesis goes through HCC progenitor cells (HcPCs) to fully established HCC, and the mechanisms driving the development of HcPCs are still largely unknown.
