1. Mutational landscape of head and neck squamous cell carcinomas in a South Asian population
Abstract Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer type globally and contributes significantly to burden of disease in South Asia. In Pakistan, HNSCC is among the most commonly diagnosed cancer in males and females. The increasing regional burden of HNSCC along with a unique set of risk factors merited a deeper investigati

2. The E3 ligase MuRF2 plays a key role in the functional capacity of skeletal muscle fibroblasts
Fibroblasts are a highly heterogeneous population of cells, being found in a large number of different tissues. These cells produce the extracellular matrix, which is essential to preserve structural integrity of connective tissues. Fibroblasts are frequently engaged in migration and remodeling, exerting traction forces in the extracellular matrix, which is

3. Trypanosoma cruzi down-regulates mechanosensitive proteins in cardiomyocytes
BACKGROUND Cardiac physiology depends on coupling and electrical and mechanical coordination through the intercalated disc. Focal adhesions offer mechanical support and signal transduction events during heart contraction-relaxation processes. Talin links integrins to the actin cytoskeleton and serves as a scaffold for the recruitment of other proteins, suc

4. Antitumoral effects of Amblyomma sculptum Berlese saliva in neuroblastoma cell lines involve cytoskeletal deconstruction and cell cycle arrest
Resumo As propriedades antitumorais de extratos de glândulas salivares de carrapatos ou proteínas recombinantes foram relatadas recentemente, mas pouco se sabe sobre as propriedades antitumorais dos componentes secretados da saliva. O objetivo deste estudo foi investigar o efeito in vitro da saliva bruta do carrapato duro Amblyomma sculptum sobre as linha

5. Glutathione depletion triggers actin cytoskeleton changes via actin-binding proteins
Abstract The importance of glutathione (GSH) in alternative cellular roles to the canonically proposed, were analyzed in a model unable to synthesize GSH. Gene expression analysis shows that the regulation of the actin cytoskeleton pathway is strongly impacted by the absence of GSH. To test this hypothesis, we evaluate the effect of GSH depletion via buthion

6. Morpho/Proteomic Comparative between High Grade Pleomorphic Sarcoma and Metastasis Diagnosed in an Old Captive Common Hippo
Old age is a risk factor for cancer development in humans and animals, and studies have shown that tumors in animals are acceptable models for studying human cancers, considering the similarities between their factors. This work was conducted in a 53-year-old captive female common hippo (Hippopotamus amphibious) with a left leg tumor and metastatic mass. His

7. Revealing potential long non-coding RNA biomarkers in lung adenocarcinoma using long non-coding RNA-mediated competitive endogenous RNA network
In our study, we aimed to reveal potential long non-coding RNAs (lncRNA) biomarkers in lung adenocarcinoma (LAD) using lncRNA-mediated competing endogenous RNAs (ceRNAs) network (LMCN). Competing lncRNA-mRNA interactions were identified using the hypergeometric test. Co-expression analysis for the competing lncRNA-mRNA interactions was implemented, and relyi

8. Numeric reconstruction of 2D cellular actomyosin network from substrate displacement
Introduction: One of the fundamental structural elements of the cell is the cytoskeleton. Along with myosin, actin microfilaments are responsible for cellular contractions, and their organization may be related to pathological changes in myocardial tissue. Due to the complexity of factors involved, numerical modeling of the cytoskeleton has the potential to

9. JVG9, a benzimidazole derivative, alters the surface and cytoskeleton of Trypanosoma cruzi bloodstream trypomastigotes
Trypanosoma cruzi has a particular cytoskeleton that consists of a subpellicular network of microtubules and actin microfilaments. Therefore, it is an excellent target for the development of new anti-parasitic drugs. Benzimidazole 2-carbamates, a class of well-known broad-spectrum anthelmintics, have been shown to inhibit the in vitro growth of many protozoa

10. Expressão das proteínas citoesqueléticas actina e tubulina em células osteogênicas cultivadas sobre vidro e vitrocerâmica bioativos / Expression of the cytoskeletal proteins actin and tubulin in osteogenic cells cultured on bioactive glass-based surfaces
Bioactive glasses and glass-ceramics have been successfully applied in various therapeutic strategies to promote the formation of mineralized matrix in bone defects. The exposure of these materials to biological fluids results in chemical and topographical modifications that may affect the interactions of cells with the biomaterial surface, with potential ef

11. Prokaryotic cells: structural organisation of the cytoskeleton and organelles
For many years, prokaryotic cells were distinguished from eukaryotic cells based on the simplicity of their cytoplasm, in which the presence of organelles and cytoskeletal structures had not been discovered. Based on current knowledge, this review describes the complex components of the prokaryotic cell cytoskeleton, including (i) tubulin homologues composed

12. O papel do jaspamídeo na dinâmica do citoesqueleto de actina das células de melanoma: relação com migração e invasão. / The role of jaspamide in the actin cytoskeleton of melanoma cells: the relation between migration and invasion.
No processo de metástase os movimentos de migração e invasão tem um papel essencial e em ambos a função dos microfilamentos é de grande importância. Neste contexto, o presente trabalho buscoui analisar os efeitos da droga jaspamídeo e após a determinação das concentrações de IC50 para as linhagens HT144 e NGM foram estudados os efeitos da droga
