Comparative Genomics and Functional Evidence for Convergent Adaptation to Hypoxia in Mammals

open access: yesIntegrative Zoology, EarlyView.
This study reveals convergent selection in mammals adapted to hypoxia. Functional assays demonstrate that amino acid mutations reduce oxidative stress, attenuate hypoxia‐induced injury, and modulate the hypoxia‐inducible transcription factor (HIF)‐driven hypoxic response.

Data‐driven thresholds for standardized classification of severe Alzheimer's disease neuropathology using digital neuropathology

open access: yesBrain Pathology, EarlyView.
We generated digital pathologic algorithms (AI‐based modules that can be freely shared) to: optimize the sampling (ROI) for diagnosis of ADNC‐related tau pathology; compare/transition between Aperio and HALO platforms; and rationalize severe Braak NFT staging, so that all Braak‐VI cases had dementia, and all Braak‐V cases had MCI or dementia.

ZmMADS47 Regulates Zein Gene Transcription through Interaction with Opaque2. [PDF]

open access: yesPLoS Genetics, 2016
Zeins, the predominent storage proteins in maize endosperm, are encoded by multiple genes and gene families. However, only a few transcriptional factors for zein gene regulation have been functionally characterized.

Non‐Alzheimer Aβ deposits in the human CNS: Implications with hypoxia and related conditions

open access: yesBrain Pathology, EarlyView.
An Aβ deposit in a non‐Alzheimer's brain from an individual who experienced hypoxia/energy failure. Abstract We recently reported the deposition of Aβ in the frontal cortex of individuals who died of acute coronavirus disease 2019 (COVID‐19), or who did not have COVID‐19 but had respiratory distress, or infants with severe cardiac malformations.

Targeting protein–protein interactions with reversible covalent modalities: Non‐cysteine chemistries

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Protein–protein interactions (PPIs) are central to diverse cellular functions, and represent a rapidly expanding class of therapeutic targets. Advancements in covalent drug design have enabled small‐molecule drugs to overcome challenges associated with engaging these targets, such as limited durations of action and difficult‐to‐drug (expansive,

Hypercortisolism: Causes, Consequences and Clinical Significance – A Review of Pathophysiology

open access: yesDiabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Hypercortisolism or Cushing syndrome is a heterogeneous clinical spectrum caused by chronic glucocorticoid excess, ranging from exogenous Cushing syndrome to rare endogenous aetiologies and the increasingly recognised entity of mild autonomous cortisol secretion (MACS). Physiological cortisol production is tightly regulated by the hypothalamic–

RAB4A acts as a negative feedback regulator of extracellular vesicle secretion during TGF‐β signaling

open access: yesThe FEBS Journal, EarlyView.
TGF‐β signaling regulates extracellular vesicle (EV) release in cancer cells by modulating the expression and activity of genes associated with EV biogenesis. The TGF‐β‐induced upregulation of RAB4A expression facilitates fast endosomal recycling, a process that limits the fusion of multivesicular bodies with the plasma membrane and EV secretion. Hence,

Iloperidone treatment mitigates the Juvenile Huntington's Disease phenotype possibly via Sigma‐1 Receptor Modulation

open access: yesThe FEBS Journal, EarlyView.
We investigated the potential of iloperidone as an activator of Sigma‐1 receptor (S1R) neuroprotective function in juvenile Huntington's disease (jHD). We tested iloperidone on cortical neurons differentiated from patient‐derived iPSCs, demonstrating that it acts as a S1R agonist, decreasing apoptosis, huntingtin aggregation, and oxidative stress ...

Mutual antagonism between auxin and diacylglycerol acyltransferase 2 regulates high‐temperature‐induced hypocotyl elongation

open access: yesNew Phytologist, EarlyView.
Proposed model for auxin–DGAT2 crosstalk regulating high‐temperature‐induced hypocotyl elongation. Summary Cell elongation is a fundamental process in plant growth and development, and it is significantly affected by temperature changes. While the signaling mechanisms driving high‐temperature‐induced cell elongation have been extensively studied, the ...

PISTILLATA paralogs in Tarenaya hassleriana have diverged in interaction specificity

open access: yesBMC Plant Biology, 2018
Background Floral organs are specified by MADS-domain transcription factors that act in a combinatorial manner, as summarized in the (A)BCE model.
