Supervillin Reorganizes The Actin Cytoskeleton And Increases Invadopodial Efficiency, Jessica Lynn Crowley, Tara C. Smith, Zhiyou Fang, Norio Takizawa, Elizabeth J. Luna

Tumor cells use actin-rich protrusions called invadopodia to degrade extracellular matrix (ECM) and invade tissues; related structures, termed podosomes, are sites of dynamic ECM interaction. We show here that supervillin (SV), a peripheral membrane protein that binds F-actin and myosin II, reorganizes the actin cytoskeleton and potentiates invadopodial function. Overexpressed SV induces redistribution of lamellipodial cortactin and lamellipodin/RAPH1/PREL1 away from the cell periphery to internal sites and concomitantly increases the numbers of F-actin punctae. Most punctae are highly dynamic and colocalize with the podosome/invadopodial proteins, cortactin, Tks5, and cdc42. Cortactin binds SV sequences in vitro and contributes to the formation …
A Comparitive Study On Traumatic Reticuloperitonitis And Traumatic Pericarditis In Egyptian Cattle, Mohamed M. Ghanem
A Comparitive Study On Traumatic Reticuloperitonitis And Traumatic Pericarditis In Egyptian Cattle, Mohamed M. Ghanem
Turkish Journal of Veterinary & Animal Sciences
This study was carried out on 15 Holstein cows divided into 3 groups of 5. Group 1 was the control, group 2 had traumatic reticuloperitonitis (TRP), and group 3 had traumatic pericarditis (TP). Comparison between the groups included clinical, hematological, biochemical, and ultrasonographic changes. TRP cows had arched backs, a sharp decrease in milk yield, and a reluctance to move, with abduction of the fore limbs. TP cows had edema of the brisket and submandibular region, with jugular vein distension and pulsation. TRP cows had a significant increase in PCV, leukocytes, and neutrophils, and a significant decrease in RBC, hemoglobin, …

Frequency And Antibiotic Susceptibility Of Pasteurella Multocida And Mannheimia Haemolytica Isolates From Nasal Cavities Of Cattle, Kaan Önat, Serpi̇l Kahya, K. Tayfun Çarli
Turkish Journal of Veterinary & Animal Sciences
The aim of the present study was to determine the frequency of Pasteurella multocida and Mannheimia haemolytica from nasal cavities of cattle, and to find antibiotic susceptibility profiles of the isolates. Bilateral nasal swab samples were collected from 47 clinically healthy Holstein cattle, with no history of antimicrobial treatment prior to sampling. Respectively, 5 and 27 isolates were identified as M. haemolytica and P. multocida. Seventeen samples from cattle of 1 year or younger were found to have P. multocida. On the other hand, from 29 samples from cattle of 2 years or older, 10 P. multocida and 5 M. …
