Dual native G‐quadruplex folding is associated with chromatin looping at the MYC locus

FEBS Open Bio, EarlyView.
BG4‐detectable G‐quadruplex (G4) in HaCaT and NHEK keratinocytes identified folded and unfolded G4s enriched at promoters/TSSs and active enhancers, whereas unfolded G4s also overlapped weak/poised enhancers. At MYC–PVT1, 3C‐qPCR detected enhancer–promoter looping only when G4s were simultaneously folded at both regulatory elements under native ...

Modification of Silk Fibers via β-cyclodextrin – Empirical Modeling and Process Optimization Using Response Surface Methodology

Journal of Natural Fibers, 2020
Modification of silk fabric via grafting with β-cyclodextrin (β-CD) using citric acid (CA) as a cross-linking agent was studied and optimized. A four-factor central composite design combined with response surface methodology (RSM) was employed to ...

GelMA‐based 3D spheroids recapitulate transcriptomic and functional hallmarks of myeloid sarcoma

FEBS Open Bio, EarlyView.
GelMA 5% hydrogels support the formation of myeloid leukemia spheroids that recapitulate MS‐specific features, including G1 arrest, apoptosis, and ECM‐driven transcriptomic reprogramming. The 3D model mimicked soft‐tissue‐like stiffness and oxygen conditions, and transcriptomic convergence with primary MS samples confirmed its utility as a preclinical ...

Photo-enzymatic dityrosine crosslinking for bioprinting [PDF]

, 2022
In this research work, we demonstrate photo-triggering of the horseradish peroxidase (HRP) dityrosine crosslinking. The photo-enzymatic crosslinking of tyramine modified alginate was obtained by introducing riboflavin as a photosensitizer, and by ...

The effects of crosslinking byproducts on the electrical properties of low density polyethylene

, 2011
Crosslinked polyethylene (XLPE) is widely used for high voltage insulation in power transmission systems. However, it has been found that, after crosslinking with Dicumyl Peroxide (DCP), the crosslinking byproducts such as acetophenone, ?-methylstyrene ...

Accelerating the crosslinking process of hyperbranched polycarbosilane by UV irradiation

, 2017
A liquid hyperbranched polycarbosilane (LHBPCS) with stoichiometric C/Si ratio but without unsaturated groups was synthesized. Different from traditional thermal crosslinking, ultraviolet (UV) irradiation crosslinking was taken. The molecular weight, the

Keratoconus: A biomechanical perspective on loss of corneal stiffness

Indian Journal of Ophthalmology, 2013
Keratoconus (KC) is progressive disease of corneal thinning, steepening and collagen degradation. Biomechanics of the cornea is maintained by the intricate collagen network, which is responsible for its unique shape and function.
