1. Long non-coding RNA HOTAIR induces the PI3K/AKT/mTOR signaling pathway in breast cancer cells
SUMMARY OBJECTIVE: The phosphoinositide 3-kinase/protein kinase AKT/mammalian target of rapamycin signaling pathway is essential for proper cellular metabolism and cell growth. However, aberrant activation of this pathway has been linked to the progression and metastasis of breast cancer. Recently, the role of long non-coding RNAs in interfering with the ce

2. Alumina applied in bone regeneration: Porous α-alumina and transition alumina
Abstract Alumina is a polymorphic bioceramic that has been extensively investigated for application in bone regeneration. Dense α-alumina has been considered a suitable biomaterial for dental and orthopedic implants due to its superior mechanical properties. However, its use is limited due to its high inertia in a biological environment. Recent investigatio

3. Enhancement of cellular activity in hyperglycemic mice dermal wounds dressed with chitosan-alginate membranes
The use of specially designed wound dressings could be an important alternative to facilitate the healing process of wounds in the hyperglycemic state. Biocompatible dressings combining chitosan and alginate can speed up wound healing by modulating the inflammatory phase, stimulating fibroblast proliferation, and aiding in remodeling phases. However, this bi

4. Fatal hemothorax caused by pleural mesothelioma in a lion
RESUMO: O mesotelioma é considerado um neoplasma maligna causada pela proliferação de células mesoteliais, principalmente da pleura, peritôneo e pericárdio. O presente caso descreve os achados macroscópicos, microscópicos e imuno-histoquímicos do hemotórax fatal causado por um mesotelioma pleural em um leão. Macroscopicamente, na cavidade torácic

5. Mechanisms by Which Metabolic Reprogramming in GSD1 Liver Generates a Favorable Tumorigenic Environment
Abstract Glycogen storage disease type 1 (GSD1) is an inherited disorder caused by impaired glucose 6-phosphatase activity. This impairment translates into the inhibition of endogenous glucose production and the subsequent accumulation of cellular glucose 6-phosphate. Excess glucose 6-phosphate enhances glycolysis, increases the production of fatty acids, ur

6. Isolation, cultivation and immunofluorescence characterization of lamellar keratinocytes from equine hoof by using explants
RESUMO: É notória a importância do casco na saúde dos equinos, mas o conhecimento em nível celular é pouco entendido. Estudos envolvendo o cultivo de queratinócitos equinos são escassos. Sabe-se que o desenvolvimento de cultivos de queratinócitos in vitro é uma condição para estudos sobre a biologia molecular, crescimento e diferenciação celula

7. Synthesis of New 1,2,3-Triazolo-naphthalimide/phthalimide Conjugates via ‘Click' Reaction: DNA Intercalation and Cytotoxic Studies
Cancer is a complex disease which involves abnormalities of multiple cellular pathways. Current chemotherapeutic drugs are mainly designed to target the DNA and cell division. Therefore, in the present study, we have synthesized a new series of 1,2,3-triazolo-naphthalimide/phthalimide conjugates and evaluated their in vitro cytotoxicity against selected huma

8. Effect of risperidone on proliferation and apoptosis of MC3T3-E1 cells
This aim of this study was to assess the molecular mechanism of osteoporosis in schizophrenia patients with risperidone use. Here, we investigated the effects of risperidone on cellular proliferation and apoptosis of a preosteoblast cell line, MC3T3-E1. Cell viability and apoptotic rate of MC3T3-E1 were detected by cell counting kit-8 and flow cytometry at a

9. Cytotoxicity of intracanal dressings on apical papilla cells differ upon activation with E. faecalis LTA
Abstract Objective The aim of this study was to investigate the cytotoxic effects of modified triple antibiotic paste and an experimental composition using calcium hydroxide on lipoteichoic acid (LTA)-primed apical papilla cells (APC). Material and Methods Human APC were tested for in vitro cytotoxicity of modified Triple Antibiotic Paste (mTAP – Cipro

10. Biological modulation of corneal epithelial wound healing
RESUMO A transparência e a manutenção da integridade epitelial da córnea são essenciais para suas propriedades ópticas e, para preservar tais características, o epitélio sofre renovação contínua. Essa renovação depende do controle da proliferação e diferenciação celular mediadas por fatores mitogênicos responsáveis pelo aumento das mitoses

11. YAP activation promotes the transdifferentiation of cardiac fibroblasts to myofibroblasts in matrix remodeling of dilated cardiomyopathy
Yes-associated protein (YAP) is an important regulator of cellular proliferation and transdifferentiation. However, little is known about the mechanisms underlying myofibroblast transdifferentiation in dilated cardiomyopathy (DCM). We investigated the role of YAP in the pathological process of cardiac matrix remodeling. A classic model of DCM was established

12. Human polyomaviruses and cancer: an overview
The name of the family Polyomaviridae, derives from the early observation that cells infected with murine polyomavirus induced multiple (poly) tumors (omas) in immunocompromised mice. Subsequent studies showed that many members of this family exhibit the capacity of mediating cell transformation and tumorigenesis in different experimental models. The transfo
