Studies of tyrosine phosphorylation in the human duodenum have indicated that proliferating cells in the middle portion of the duodenal crypt were devoid of this feature, suggesting that tyrosine kinase activation is not a dominant factor in crypt cell proliferation, and that consequently tyrosine phosphatase activity may be a more critical factor in crypt cell development. We investigated the ...
Focal adhesions are complex multi-molecular structures that link the actin cytoskeleton to the extracellular matrix through integrin adhesion receptors and play a key role in regulation of many cellular functions. LAR (also known as PTPRF) is a receptor protein tyrosine phosphatase that regulates PDGF signalling and localises to focal adhesions. We have observed that loss of LAR phosphatase act...
OBJECTIVE To understand how a pilot intervention combining SMS reminders with real-time adherence monitoring improved adherence to HIV antiretroviral therapy (ART) for adults initiating treatment in rural Uganda. DESIGN Qualitative study, conducted with a pilot randomized controlled trial. METHODS Sixty-two pilot intervention study participants took part in qualitative interviews on: prefer...
In a randomized, double-blind, Phase III study, we compared pasireotide long-acting release (pasireotide LAR) with octreotide long-acting repeatable (octreotide LAR) in managing carcinoid symptoms refractory to first-generation somatostatin analogues. Adults with carcinoid tumors of the digestive tract were randomly assigned (1:1) to receive pasireotide LAR (60 mg) or octreotide LAR (40 mg) eve...
Receptor-linked tyrosine phosphatases regulate cell growth by dephosphorylating proteins involved in tyrosine kinase signal transduction. The leukocyte common antigen-related (LAR) tyrosine phosphatase receptor has sequence similarity to the neural cell adhesion molecule N-CAM and is located in a chromosomal region (1p32-33) frequently altered in neuroectodermal tumors. To understand the functi...
This commentary uses Paul Gilroy’s controversial claim that new technoscientific processes are instituting an ‘end to race’ as a provocation discuss the epistemological transformation of race in algorithmic culture. We situate within context abolitionist agenda against racial-thinking, underscoring relationship between his post-race polemic and post-visual discourse. then challenges studying re...
The follicle cell monolayer that encircles each developing Drosophila oocyte contributes actively to egg development and patterning, and also represents a model stem cell-derived epithelium. We have identified mutations in the receptor-like transmembrane tyrosine phosphatase Lar that disorganize follicle formation, block egg chamber elongation and disrupt Oskar localization, which is an indicat...
Synaptic adhesion molecules orchestrate synaptogenesis. The presynaptic leukocyte common antigen-related receptor protein tyrosine phosphatases (LAR-RPTPs) regulate synapse development by interacting with postsynaptic Slit- and Trk-like family proteins (Slitrks), which harbour two extracellular leucine-rich repeats (LRR1 and LRR2). Here we identify the minimal regions of the LAR-RPTPs and Slitr...
CONTEXT Chronic abdominal pain is the most difficult management issue in patients with chronic pancreatitis. Recently, a long-acting depo-formulated version of octreotide has been developed that can be given as a once monthly intramuscular injection, Octreotide LAR(R) (O-LAR) rather than as a thrice daily subcutaneous injection (octreotide short-acting, O-SA). OBJECTIVE To see if O-LAR is sim...
Local Allergic Rhinitis (LAR) is an emerging disease. However, its incidence in the pediatric population has not yet been studied. The gold-standard for the diagnosis is the nasal provocation test that is not everywhere available and difficult to apply in children. The aim of our study is to evaluate the nasal lavage fluid IgE as a biomarker of LAR in children. 54 pediatric patients [IQR 4.0-12...
