Ugonin P facilitates chondrogenic properties in chondrocytes by inhibiting miR-3074-5p production: implications for the treatment of arthritic disorders.

Arthritis is a chronic inflammatory disease that causes joint damage, with osteoarthritis (OA) and rheumatoid arthritis (RA) being the most common types. Both conditions are characterized by cartilage degradation due to an imbalance between repair and breakdown processes. Chondrocytes, the key cells in articular cartilage, maintain its structure by producing an extracellular matrix rich in aggrecan and type II collagen (COL2).

Ugonin inhibits chondrosarcoma metastasis through suppressing cathepsin V via promoting miR-4799-5p expression.

Chondrosarcoma is a rare type of bone cancer that develops in cartilage cells. In recent years, the incidence of chondrosarcomas has steadily increased worldwide. During the advanced stages, chondrosarcoma carries a significant risk of metastasis and exhibits resistance to both chemotherapy and radiation therapy.

Vector-Free Deep Tissue Targeting of DNA/RNA Therapeutics via Single Capacitive Discharge Conductivity-Clamped Gene Electrotransfer.

Viral vector and lipid nanoparticle based gene delivery have limitations around spatiotemporal control, transgene packaging size, and vector immune reactivity, compromising translation of nucleic acid (NA) therapeutics. In the emerging field of DNA and particularly RNA-based gene therapies, vector-free delivery platforms are identified as a key unmet need. Here, this work addresses these challenges through gene electrotransfer (GET) of "naked" polyanionic DNA/mRNA using a single needle form-factor which supports "electro-lens" based compression of the local electric field, and local control of tissue conductivity, enabling single capacitive discharge minimal charge gene delivery.

Development of an optimized SEC method for characterization of genome DNA leakage from adeno-associated virus products.

Adeno-associated virus (AAV) vectors are widely used to deliver therapeutic transgenes due to their superior safety, relatively low immunogenicity, and ability to target diverse tissues. AAV gene therapy products are typically formulated as frozen liquid and stored below - 60 °C, and therefore are subjected to multiple freeze/thaw cycles during manufacturing and administration. Recent studies have shown that genome DNA leakage could be induced by freeze/thaw stress.
