Preconditioning of mesenchymal stromal cells with low-intensity ultrasound: influence on chondrogenesis and directed SOX9 signaling pathways [PDF]

open access: yes, 2020
Background: Continuous low-intensity ultrasound (cLIUS) facilitates the chondrogenic differentiation of human mesenchymal stromal cells (MSCs) in the absence of exogenously added transforming growth factor-beta (TGFβ) by upregulating the expression of ...

Photothermal Hydrogel with Mn3O4 Nanoparticles Alleviates Intervertebral Disc Degeneration by Scavenging ROS and Regulating Extracellular Matrix Metabolism

open access: yesAdvanced Functional Materials, EarlyView.
The MPTT‐nanozyme‐hydrogel system (Mn3O4@ChS‐HA) provides a multifunctional therapeutic strategy for intervertebral disc degeneration (IVDD), effectively targeting oxidative stress and enhancing AF repair by restoring extracellular matrix (ECM) and redox homeostasis.

Viral dynamics of acute HIV-1 infection. [PDF]

open access: yes, 1999
Viral dynamics were intensively investigated in eight patients with acute HIV infection to define the earliest rates of change in plasma HIV RNA before and after the start of antiretroviral therapy. We report the first estimates of the basic reproductive

Phenotypic mixing and hiding may contribute to memory in viral quasispecies [PDF]

open access: yes, 2003
Background. In a number of recent experiments with food-and-mouth disease virus, a deleterious mutant, was found to avoid extinction and remain in the population for long periods of time. This observation was called quasispecies memory.

Synthetic Strategy for mRNA Encapsulation and Gene Delivery with Nanoscale Metal‐Organic Frameworks

open access: yesAdvanced Functional Materials, EarlyView.
This research utilizes the ZIF‐8 for the encapsulation and intracellular delivery of nucleic acids, specifically mRNA, for applications in gene delivery. Integrating PEI addresses the issue of mRNA leakage from ZIF‐8, resulting in the delivery and expression of green fluorescent protein (GFP) in vitro and firefly luciferase in vivo.

Dynamics and clinical relevance of maternal mRNA clearance during the oocyte-to-embryo transition in humans

open access: yesNature Communications, 2020
How maternal RNA clearance is regulated in human preimplantation embryos is unclear. Here, the authors show there is a potential correlation between maternal mRNA decay defects and early developmental arrest from in vitro fertilized human embryos ...

Impact of HuR inhibition by the small molecule MS-444 on colorectal cancer cell tumorigenesis. [PDF]

open access: yes, 2016
Colorectal cancer (CRC) is the third most common cancer and a leading cause of cancer-related mortality. Observed during CRC tumorigenesis is loss of post-transcriptional regulation of tumor-promoting genes such as COX-2, TNFα and VEGF. Overexpression of

Fluorescence-based quantification of messenger RNA and plasmid DNA decay kinetics in extracellular biological fluids and cell extracts [PDF]

open access: yes, 2020
Extracellular and intracellular degradation of nucleic acids remains an issue in non-viral gene therapy. Understanding biodegradation is critical for the rational design of gene therapeutics in order to maintain stability and functionality at the target ...

Metal Nanoclusters for Cancer Imaging and Treatment

open access: yesAdvanced Functional Materials, EarlyView.
This review aims to provide a comprehensive summary and discussion of the core–shell design capabilities of metal nanoclusters (NCs) at the atomic level for cancer imaging and treatment. It offers essential insights into the design principles of metal NCs while also encouraging the exploration of other nanomaterials and their potential theranostic ...
