Therapeutic potential of clinical-grade human induced pluripotent stem cell-derived cardiac tissuesCentral MessagePerspective

open access: yesJTCVS Open, 2021
Objectives: To establish a protocol to prepare and transplant clinical-grade human induced pluripotent stem cell (hiPSC)-derived cardiac tissues (HiCTs) and to evaluate the therapeutic potential in an animal myocardial infarction (MI) model.

A stepwise emergence of evolution in the RNA world

open access: yesFEBS Letters, EarlyView.
How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

Interplay between cell growth and cell cycle in plants.

open access: yesJournal of Experimental Botany, 2014
The growth of organs and whole plants depends on both cell growth and cell-cycle progression, but the interaction between both processes is poorly understood.

Generation of HIV-Resistant Macrophages from IPSCs by Using Transcriptional Gene Silencing and Promoter-Targeted RNA

open access: yesMolecular Therapy: Nucleic Acids, 2018
Highly active antiretroviral therapy (HAART) has markedly prolonged the prognosis of HIV-1 patients. However, lifelong dependency on HAART is a continuing challenge, and an effective therapeutic is much desired.

AMPK activation reverts mouse epiblast stem cells to naive state

open access: yesiScience, 2021
Summary: Despite increasing knowledge on primed and naive pluripotency, the cell signaling that regulates the pluripotency type in stem cells remains not fully understood.

The TSC1-TSC2 complex: a molecular switchboard controlling cell growth.

open access: yesBiochemical Journal, 2008
TSC1 and TSC2 are the tumour-suppressor genes mutated in the tumour syndrome TSC (tuberous sclerosis complex). Their gene products form a complex that has become the focus of many signal transduction researchers. The TSC1-TSC2 (hamartin-tuberin) complex,

Modifications in FLAP's second cytosolic loop influence 5‐LOX interaction, inhibitor binding, and leukotriene formation

open access: yesFEBS Letters, EarlyView.
The enzyme 5‐lipoxygenase (5‐LOX) catalyzes the first step in the biosynthesis of leukotrienes (LTs) involved in inflammatory pathophysiology. After cellular stimulation, 5‐LOX translocates to the nucleus, interacting with the 5‐LOX‐activating protein (FLAP) to form LTA4 from arachidonic acid (AA).

Modified poloxamer 407 and hyaluronic acid thermosensitive hydrogel-encapsulated keratinocyte growth factor 2 improves knee osteoarthritis in rats

open access: yesMaterials & Design, 2021
Osteoarthritis (OA) is one of the most common chronic diseases, causing degenerative changes in articular cartilage and subchondral bones. To date, there is no effective drug to delay the progression of OA in clinical practice.
