PANoptosis in the pathogenesis of myelodysplastic syndromes

Molecular Oncology, EarlyView.
PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...

Multi-site passivation agent for efficient tandem solar cells: Simultaneously suppressing defect recombination in NiOx surface, perovskite buried interface, and silicon edge

eScience
Wide-band gap perovskites combined with silicon (Si) in tandem solar cells offer a cost-effective path to industrialization. However, surface recombination at the buried interface of perovskite solar cells (PSCs) and the edge surface of Si solar cells ...

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

New Route for “Cold-Passivation” of Defects in Tin-Based Oxides [PDF]

The Journal of Physical Chemistry C, 2018
Transparent conductive oxides (TCOs) are essential in technologies coupling light and electricity. For Sn-based TCOs, oxygen deficiencies and undercoordinated Sn atoms result in an extended density of states below the conduction band edge. Although shallow states provide free carriers necessary for electrical conductivity, deeper states inside the band

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

FEBS 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 ...

Defect Passivation of CsPbBr3 with AgBr for High‐Performance All‐Inorganic Perovskite Solar Cells

Advanced Energy & Sustainability Research, 2021
CsPbBr3‐based perovskite solar cells possess both high humidity and temperature tolerance, and also have excellent long‐term stability in air, but the defect states in the bulk perovskite are always an obstacle for further improvement of their efficiency.
