Background: Human mesenchymal stromal cells (MSCs) possess regenerative potential due to pluripotency and paracrine functions. However, their stemness and immunomodulatory capabilities are sub-optimal in conventional two-dimensional (2D) culture.

Aim: To enhance the efficiency and therapeutic efficacy of MSCs, an -like 3D culture condition was applied.

HEK293T cells are extensively utilized for therapeutic protein production due to their human origin, which enables accurate post-translational modifications. This study aimed to enhance membrane protein production in HEK293T cells by knocking out the ATF4 gene using CRISPR-Cas9 technology. The ATF4 gene was edited by infecting HEK293T cells with a lentivirus carrying optimized single-guide RNA (ATF4-KO-3) and Cas9 genes.

Although pancreatic cancer presents with one of the most unfavorable prognoses, its treatment options are very limited. Mitochondria-targeting moieties, considered a new and prominent treatment modality, are expected to demonstrate synergistic anticancer effects due to their distinct mechanism compared to conventional chemotherapeutic approaches. This study evaluated the therapeutic potential of mitochondria-accumulating self-assembly peptides, referred to as Mito-FFs, utilizing both in vitro and in vivo pancreatic cancer models.

Background: Previous studies reported significant relationships between obesity and pulmonary dysfunction. Here, we investigated genetic alterations in the lung tissues of high fat diet (HFD) induced obese mouse through transcriptomic and molecular analyses.

Methods: Eight-week-old male C57BL/6J mice were fed either a normal chow diet (NCD) or HFD for 12 weeks.

This study aims to assess the feasibility of expanding the powder size distribution (PSD) of Ti-6Al-4V grade 5 powder for LPBF to achieve cost reduction. Parameter optimization to minimize the degradation of mechanical properties due to the expanded particle size distribution was conducted. Mechanical tests for specimens built using optimized parameters revealed minor reductions in strength: 3.
