Nanoparticle-Delivered microRNA-153-3p Alleviates Myocardial Infarction-Induced Myocardial Injury in a Rat Model
Although
microRNA-153-3p (miR-153-3p) has been demonstrated to
confer protective roles in ischemia/reperfusion injury, its potential
role in myocardial infarction (MI) remains undefined. Small-molecule
modifiers and nanoparticles loaded with microRNAs (miRNAs) have emerged
as potential therapeutic reagents for MI treatment. In this study,
we prepared liposome nanoparticles, hyaluronic acid (HA)-cationic
liposomes (CLPs) complex, for the delivery of miR-153-3p and delineated
the mechanistic actions of miR-153-3p modified by nHA-CLPs in MI-induced
injury. Our data suggested that nHA-CLPs-loaded miR-153-3p protected
cardiomyocytes against MI-induced cardiomyocyte apoptosis and myocardial
injury. miR-153-3p was bioinformatically predicted and experimentally
verified to bind to Krüppel-like factor 5 (KLF5) 3’UTR
and negatively regulate its expression. Hypoxia was adopted to stimulate
MI-induced injury to cardiomyocytes in vitro, in which miR-153-3p
presented anti-apoptotic potential. However, restoration of KLF5 reversed
this anti-apoptotic effect of miR-153-3p. Furthermore, KLF5 was demonstrated
to be an activator of the NF-κB pathway. KLF5 enhanced cardiomyocyte
apoptosis and inflammation under hypoxic conditions through NF-κB
pathway activation, while nHA-CLPs-loaded miR-153-3p suppressed inflammation
by blocking the NF-κB pathway. Collectively, our findings suggested
the cardioprotective role of miR-153-3p against MI and the successful
delivery of miR-153-3p by nHA-CLPs. The identification of KLF5-mediated
activation of NF-κB pathway as an apoptotic and inflammatory
mechanism aids in better understanding of the biology of MI and development
of novel therapeutic strategies for MI

Aggregation-Induced Enhancement Effect of Gold Nanoparticles on Triplet Excited State
Remarkable
optical properties are posed with gold nanoparticles (AuNPs) due to
the excitation of localized surface plasmon resonances, which makes
AuNPs affect strongly both the ground state and the excited state
of adjacent organic molecules. Compared with the ground state, the
effect of AuNPs on excited state of organic molecules is not always
fully understood. Here, we performed transient UV–vis absorption
experiments to monitor the triplet excited state formation of three
cationic dyes and one anionic dye in the presence of two types of
gold nanoparticles: the citrate-stabilized AuNPs and ATP-protected
AuNPs. It is found that the three cationic dyes can cause efficient
aggregation of citrate-stabilized AuNPs, leading to AuNPs aggregates
with varied size, whereas the ATP-protected AuNPs can be sustained
in the monodispersed state. By comparing the circumstances of aggregated
AuNPs and monodispersed AuNPs, we demonstrate that the enhancement
effect on triplet excited state formation results from the aggregation
of gold nanoparticles and depends on the aggregation size. These findings
reveal the aggregation induced plasmon field interaction of AuNPs
with excited state population dynamics and may enable new applications
of aggregated metal nanoparticles, where aggregates can serve as stronger
plasmonic nanoantennas
The XVP/ NAC003 protein associates with the plasma membrane through KR rich regions and translocates to the nucleus by changing phosphorylation status
Membrane localized transcription factors play essential roles in various plant developmental processes. The XVP/NAC003 protein is a NAC domain transcription factor associated with the plasma membrane and involved in the TDIF-PXY signaling during vascular development. We report here the mechanisms of XVP membrane localization and its nuclear translocation. Using a transient transformation approach, we found that XVP is associated with the plasma membrane through positively charged KR-rich regions. Mutagenesis studies found that the threonine amino acid at position 354 (T354) is critical for XVP translocation to the nucleus. In particular, the threonine to alanine mutation (T354A) resulted in a partial nucleus localization, while threonine to aspartic acid (T354D) mutation showed no effect on protein localization, indicating that dephosphorylation at T354 may serve as a nucleus translocation signal. This research sheds new light on the nucleus partitioning of plasma membrane-associated transcription factors.</p
Energy Storage System Based on Recycled Polypropylene and Its Use in Lithium–Sulfur and Lithium-Ion Batteries
Nontoxic, eco-friendly,
and high-energy-density sulfurated
poly(propylene)
(S/PP-waste) has been prepared in a one-step vulcanization process
from recycled poly(propylene) waste and used as a cathode material
in lithium–sulfur (Li–S) batteries. A sulfur loading
of up to 50.4 wt % was achieved. In S/PP-waste, the sulfur is covalently
bound to the polymer matrix, selectively resulting in a solid phase
transition during charge and discharge. Consequently, the polysulfide
shuttle can be avoided, which results in satisfactory electrochemical
performance with ultralong cycle life and a low capacity decay per
cycle of ∼0.018% at 0.5C. S/PP-waste was also explored for
the first time as an anode material in LiMn2O4-based Li-ion full cells. Its good electrochemical performance as
well as its recycled nature make it a promising energy storage material
for the future
Oxygen Self-Production Red Blood Cell Carrier System for MRI Mediated Cancer Therapy: Ferryl-Hb, Sonodynamic, and Chemical Therapy
Hypoxia
in tumors can lead to insufficient oxygen supply during sonodynamic
therapy (SDT), which in turn strengthens tumor resistance to sonodynamic
efficacy. To conquer hypoxia in tumors and improve the treatment effectiveness,
we developed oxygen self-production red blood cell (RBC) carrier system
to decompose tumor endogenic H2O2 into O2 and combine triplex cancer therapy: ferryl-hemoglobin (ferryl-Hb),
sonodynamic, and chemical therapy. Both hydrophilic sonosensitizer
and doxorubicin (DOX) were encapsulated inside RBCs (DOX/Mn-TPPS@RBCs).
The drug release can be improved by combining the effects of H2O2 and ultrasonic irradiation. Here, we introduced
a contrast agent, meso-tetra (4-sulfonatephenyl)
porphyrinate manganese(III) complex (Mn-TPPS), which could be used
to enhance the signal intensity of magnetic resonance imaging (MRI)
of the tumor site. The feasibility of Mn-TPPS as a sonosensitizer
was investigated during SDT. Importantly, DOX/Mn-TPPS@RBCs overcame
hypoxia in the tumor and improved the efficacy of SDT owing to the
O2 generation by the catalase-catalyzed decomposition of
tumor endogenic H2O2. Hemoglobin was simultaneously
oxidized into highly oxidative ferryl-Hb species by H2O2 and reactive oxygen species, resulting in cytotoxicity. Overall,
this drug delivery system is a promising therapeutic agent involving
in situ production of oxygen inside the tumor, triplex therapy, and
MRI
Identification of OLA1 as a Novel Protein Target of Vitexin to Ameliorate Dextran Sulfate Sodium-Induced Colitis with Tissue Thermal Proteome Profiling
Vitexin, which exists in various medicinal plants and
food sources,
has recently received increasing attention because of its anti-inflammatory
properties. This study aims to identify the protein target of vitexin
that ameliorates dextran sulfate sodium (DSS)-induced colitis. The
results showed that vitexin not only alleviated the clinical symptoms
and colonic damage in mice with DSS-induced colitis but also suppressed
the colonic production of inflammatory cytokines (IL-1β, IL-6,
ICAM, and VCAM) and enhanced the expression of barrier-associated
proteins (ZO-1, Occludin, and E-cadherin). Based on tissue thermal
proteome profiling (Tissue-TPP) and molecular docking, OLA1 was creatively
identified as a potential protein target for vitexin. Further siRNA-mediated
knockdown of the OLA1 gene in Caco-2 cells demonstrated the ability
of OLA1 to increase Nrf2 protein expression and, thus, mediated the
anti-inflammatory effects of vitexin. Interaction of the OLA1–vitexin
complex with Keap1 protein to disrupt the Keap1-Nrf2 interaction may
be required for activating Nrf2. Our findings revealed a novel role
for OLA1 as a protein target of vitexin that contributes to its anti-inflammatory
action by activating Nrf2, which may provide a promising molecular
mechanism for novel therapeutic strategies to treat colitis and the
associated systemic inflammation
Table1_PD-1 inhibitor-based adverse events in solid tumors: A retrospective real-world study.DOCX
Background & Aims: Immune checkpoint inhibitors (ICIs) have transformed the landscape of cancer treatment, and ICI-related toxicities (i.e., immune-related adverse events (irAEs) have been reported in many clinical studies. However, the toxicity data of real-world have not been fully assessed.Methods: Patients with histologically confirmed solid tumors who had been treated with PD-1 inhibitors were included in the study. Patient data were collected from electronic medical records, including basic characteristics, data of irAEs, management and outcome. Incidences of irAEs were pooled and compared, and the risk of irAEs was also analyzed.Results: A total of 362 solid tumor patients treated with sintilimab (n = 171), camrelizumab (n = 60), toripalimab (n = 72), and pembrolizumab (n = 59) were included. In total, any grade irAEs, grade 1–2 irAEs, and grade ≥3 irAEs accounted for 47.24%, 38.67% and 8.56% of cases, reapectively. Further, 29.24% of patients discontinued immunotherapy due to irAEs, with pneumonitis being the main reason for discontinuation. By comparing the toxicity profiles between different ICIs, we found that reactive capillary haemangiomas were camrelizumab-specific. Additionally, the frequency of irAEs was association with ICIs type, the pooled incidence (standardized rate) of irAEs related to sintilimab, camrelizumab, toripalimab and pembrolizumab were 55.56% (52.81%), 48.33% (55.55%), 33.33% (29.23%) and 38.98% (38.29%), respectively. Sintilimab and camrelizumab had higher incidences of any grade and grade 1–2 than toripalimab (55.56% vs. 33.33%, p = 0.002; 48.54% vs. 25.00%, p = 0.0001) and pembrolizumab (55.56% vs. 38.98%, p = 0.0028; 48.54% vs. 25.42%, p = 0.002), while the grade ≥3 irAEs of pembrolizumab (13.56%) were approximately 1.63- to 1.93-fold higher than other ICIs, and the standardized grade ≥3 of pembrolizumab was significantly higher than that of sintilimab (13.21% vs. 7.12%, p = 0.026), especially for grade ≥3 pneumonitis. Multivariate analysis found that cumulative cycles of ICI (OR = 1.081; 95% CI: 1.023–1.142; p = 0.006), and lung cancer (OR = 1.765; 95% CI: 1.105–2.820; p = 0.017) were independent risk factors for irAEs.Conclusion: The frequency of irAEs is associated with ICI type. The pooled incidence of irAEs related to sintilimab and pneumonitis caused by pembrolizumab were higher. These data indicate the importance of having different monitoring priorities for different PD-1 inhibitors.</p
