Pseudomonas aeruginosa lectin LecB impairs keratinocyte fitness by abrogating growth factor signalling

Life Science Alliance, 2019
This study provides a novel function of the bacterial lectin LecB, which dampens cell proliferation and survival by targeting the insulin-like growth factor-1 for degradation, without receptor activation.

Binding of mutants of human insulin-like growth factor II to insulin-like growth factor binding proteins 1-6

Journal of Biological Chemistry, 1993
A family of six specific insulin-like growth factor binding proteins (IGFBPs) modulates the biological actions of the insulin-like growth factors, IGF-I and IGF-II. In the present study, we determined the binding affinity of purified human IGFBPs 1-6 for recombinant human IGF-II mutants whose binding to IGF-I, IGF-II/mannose 6-phosphate, and insulin ...

Spatial Control of Light‐Responsive Proteins and Optogenetics Within Hydrogels via Volumetric Bioprinting

Advanced Materials, EarlyView.
Spatiotemporal control over cell behavior within bioprinted constructs remains a key challenge in biofabrication. Volumetric bioprinting using multi‐wavelength light sources permits to activate light‐sensitive intracellular proteins as well as optogenetic gene and protein expression circuits in bioprinted cells, in addition to enabling fast printing of

Advanced Materials for Biologics Delivery to Brain Tumors

Advanced Materials, EarlyView.
Material innovation is central to unlocking the therapeutic potential of biologics against many central nervous system diseases, including brain cancer. By engineering carriers with controlled transport, targeting, and release properties, advanced materials can overcome the blood–brain barrier and tumor microenvironment, improving the delivery of ...

Controlling Insulin-Like Growth Factor Activity and the Modulation of Insulin-Like Growth Factor Binding Protein and Receptor Binding

Journal of Dairy Science, 1998
The insulin-like growth factors (IGF) and insulin perform seemingly unique roles by causing the same metabolic effect: cellular hypertrophy. Although overlapping, there are different consequences to cellular hypertrophy induced by IGF and that induced by insulin. The IGF enhance the cell hypertrophy that is requisite for cell survival, hyperplasia, and

Sex steroids, growth factors and mammographic density: a cross-sectional study of UK postmenopausal Caucasian and Afro-Caribbean women. [PDF]

, 2009
INTRODUCTION: Sex steroids, insulin-like growth factors (IGFs) and prolactin are breast cancer risk factors but whether their effects are mediated through mammographic density, one of the strongest risk factors for breast cancer, is unknown.

Insulin growth factor binding protein 7 is a novel target to treat dementia

Neurobiology of Disease, 2014
Alzheimer's disease (AD) is the most common form of dementia in the elderly but effective therapeutic strategies to treat AD are not yet available. This is also due to the fact that the pathological mechanisms that drive the pathogenesis of sporadic AD ...

Insulin-Like Growth Factor Binding Proteins Modulate Müller Cell Responses to Insulin-Like Growth Factors

Investigative Opthalmology & Visual Science, 2004
Müller cells are consistently identified in diabetic fibrocontractive ocular tissues and, in response to insulin-like growth factor I, generate tractional forces of the type that cause retinal detachment. Recent studies suggest that diabetes-associated increases in vitreous insulin-like growth factor activity cannot be attributed to simple increases in
