A multi-stage protocol for indirect somatic embryogenesis and plantlet regeneration from leaf explants of Quercus chungii

open access: yesIndustrial Crops and Products
Somatic embryogenesis (SE) is pivotal for mass clonal propagation in forestry, yet oak species remains recalcitrant. This study established an indirect SE protocol for Quercus chungii plantlet regeneration using leaf explants from two-year-old seedlings.

CLONAL FORESTRY OF Piptocarpha angustifolia: SURVIVAL AND GROWTH VIGOR IN FIELD CONDITIONS [PDF]

open access: yesCERNE, 2017
ABSTRACT Piptocarpha angustifolia is a potential native species for Brazilian forestry. However, a lot of challenges and technical constraints persist, hindering its expansion as a species for forest plantations, among them, the lack of evaluation of their survival and growth in field conditions.

Copper‐Driven Epithelial Barrier Disruption: A Novel Mechanism of COPD Acute Exacerbations Mediated by the TNF‐α/ATP7A Axis

open access: yesAdvanced Science, EarlyView.
This study reveals a copper‐driven mechanism of COPD acute exacerbations mediated by the TNF‐α/ATP7A axis. TNF‐α suppresses the copper transporter ATP7A via competitive NF‐κB/CREB1/CBP signaling, resulting in intracellular copper accumulation, mitochondrial oxidative stress, and epithelial barrier disruption.

Early Retinal UCHL1 Dysregulation Coupled With Synaptic Loss Reflects Alzheimer's Disease Severity

open access: yesAdvanced Science, EarlyView.
This study identifies synapse‐enriched deubiquitinase UCHL1 as an early Aβ‐responsive regulator of retinal synaptopathy in Alzheimer's disease. Retinal UCHL1 loss accompanies excitatory synapse degeneration, p75NTR activation, and neuroinflammation, and predicts Braak stage and cognitive decline. Aβ42 fibrils trigger synaptic and UCHL1 depletion before

The Natural Product Corramycin Acts as a DNA Gyrase Poison and Overcomes Fluoroquinolone Resistance in Mycobacterium tuberculosis

open access: yesAdvanced Science, EarlyView.
Corramycin, a myxobacterial natural product antibiotic, exhibits potent bactericidal activity against multidrug‐resistant Mycobacterium tuberculosis. The compound hijacks bacterial transporters such as BacA and OppABCD to enter the cell and inhibits DNA synthesis through a previously unrecognized mode of DNA gyrase poisoning, locking the enzyme in an ...
