Notably absent from the existing literature is an explicit biomechanical model linking limb design to the energy cost of locomotion, COL. Here, I present a simple model that predicts the rate of force production necessary to support the body and swing the limb during walking and running as a function of speed, limb length, limb proportion, excursion angle and stride frequency. The estimated rat...
Lpar3 is upregulated in the preimplantation uterus, and deletion of Lpar3 leads to delayed uterine receptivity in mice. Microarray analysis revealed that there was higher expression of Col3a1 and Col6a3 in the Preimplantation Day 3.5 Lpar3(-/-) uterus compared to Day 3.5 wild-type (WT) uterus. Since extracellular matrix (ECM) remodeling is indispensable during embryo implantation, and dynamic s...
Selective serotonin reuptake inhibitors reduce the attack frequency in familial mediterranean Fever.
Familial Mediterranean Fever (FMF) is characterized by recurrent acute attacks of fever and serositis, and colchicine is the primary treatment. The pathogenesis of the disease has not been fully understood. Resistance to colchicine remains to be a problem in up to 30% of the patients and yet there seems to be no alternative treatment. In this study our objective was to investigate whether a sel...
Segments of epididymal adipose tissue from normal male rats were incubated with micromolar concentrations of colchicine for different periods of time up to 4 hr, and the mobilization of free fatty acids (FFA) was measured during a subsequent reincubation. Although pretreatment with colchicine did not alter basal unstimulated FFA release, mobilization of FFA in the presence of epinephrine or the...
Colchicine, a plant alkaloid, is a potent inhibitor of mitosis and other physiological processes that involve microtubules. These effects are mediated by the specific binding of colchicine to a high-affinity receptor site on tubulin, the major protein of microtubules. It seemed possible that the colchicine site on tubulin might also be the receptor for endogenous cellular molecules. We now repo...
In spite of the many papers published on colchicine and its influence on cell division, an ac ceptable explanation for the mode of action of this drug is not yet available. There is also still much uncertainty about the action of colchicine and its derivatives on tumors. Ludford (13), using tumors and tissue culture, suggests that colchicine increases the viscosity of cell protoplasm. Northen (...
Tubulin, the subunit protein of microtubules, undergoes a time-dependent loss of functional properties known as decay. We have previously shown that the drug 2-(4-fluorophenyl)- -(2-chloro-3,5-dimethoxyphenyl)-3-methyl-6-phenyl-4(1H)-pyridinone (IKP104) accelerates decay, but that in the presence of colchicine, IKP104 becomes a stabilizer of tubulin. To see if this is due to conformational effe...
Colchicine, is an old and well-known drug, used for treatment of rheumatic diseases. Nausea, vomiting, abdominal pain, and diarrhea are the clinical symptoms of colchicine poisoning. Cardiotoxicity can lead to mortality. We report a case of colchicine intoxication complicated with complete heart block. A 9-year-old patient ingesting colchicine 0.4-0.5 mg/kg was transferred because of elevation ...
MicroRNA-185 regulates transforming growth factor-β1 and collagen-1 in hypertrophic scar fibroblasts
Transforming growth factor-β1 (TGF-β1) and collagen type I (Col-1) serve a critical role in the development and progression of hypertrophic scarring (HS). The present study hypothesized that a post‑translational mechanism of microRNAs (miR) regulated the expression of TGF‑β1 and Col‑1 in HS fibroblasts (HSFBs). A collection of 20 HS tissues was compared with corresponding normal tissues from cl...
Collier, the single Drosophila COE (Collier/EBF/Olf-1) transcription factor, is required in several developmental processes, including head patterning and specification of muscle and neuron identity during embryogenesis. To identify direct Collier (Col) targets in different cell types, we used ChIP-seq to map Col binding sites throughout the genome, at mid-embryogenesis. In vivo Col binding pea...
