1. Gene Silencing Therapeutics in Cardiology: A Review Article
Abstract Therapeutics that inhibit enzymes, receptors, ion channels, and cotransporters have long been the mainstay of cardiovascular medicine. Now, oligonucleotide therapeutics offer a modern variation on this paradigm of protein inhibition. Rather than target a protein, however, small interfering ribonucleic acids and antisense oligonucleotides target the

2. Target Search for Transcription Factors on DNA Chains
RESUMO Entre muitas estruturas presentes nas células dos seres vivos, existem proteínas chamadas fatores de transcrição (FT) que são responsáveis por inibir ou promover a transcrição do ADN. Para realizar sua função, os fatores de transcrição executam buscas aleatórias ao redor do citoplasma (para células procarióticas) e ao longo da cadeia de

3. Nanotechnology for the treatment of deep endometriosis: uptake of lipid core nanoparticles by LDL receptors in endometriotic foci
OBJECTIVE: Rapidly dividing cells in multiple types of cancer and inflammatory diseases undergo high low density lipoprotein (LDL) uptake for membrane synthesis, and coupling an LDL-like nanoemulsion, containing lipid nanoparticles (LDE) to a chemotherapeutic agent efficiently targets these cells without significant systemic effects. This was a prospective

4. Human papillomavirus and genome instability: from productive infection to cancer
Infection with high oncogenic risk human papillomavirus types is the etiological factor of cervical cancer and a major cause of other epithelial malignancies, including vulvar, vaginal, anal, penile and head and neck carcinomas. These agents affect epithelial homeostasis through the expression of specific proteins that deregulate important cellular signaling

5. Cell Division in genus Corynebacterium: protein-protein interaction and molecular docking of SepF and FtsZ in the understanding of cytokinesis in pathogenic species
ABSTRACT The genus Corynebacterium includes species of great importance in medical, veterinary and biotechnological fields. The genus-specific families (PLfams) from PATRIC have been used to observe conserved proteins associated to all species. Our results showed a large number of conserved proteins that are associated with the cellular division process. Was

6. Plant arginyltransferases (ATEs)
Abstract Regulation of protein stability and/or degradation of misfolded and damaged proteins are essential cellular processes. A part of this regulation is mediated by the so-called N-end rule proteolytic pathway, which, in concert with the ubiquitin proteasome system (UPS), drives protein degradation depending on the N-terminal amino acid sequence. One imp

7. "Photo" Chemistry Without Light?
In the early seventies, Giuseppe Cilento (São Paulo University), Emil White (Johns Hopkins University) and Angelo Lamola (AT&T Bell Laboratories) postulated that typical photochemical reactions could occur in dark parts of living organisms if coupled to enzymatic sources of electronically excited products. Their paradoxical hypothesis of "photochemistry wit

8. POD-1/Tcf21 overexpression reduces endogenous SF-1 and StAR expression in rat adrenal cells
During gonad and adrenal development, the POD-1/capsulin/TCF21transcription factor negatively regulates SF-1/NR5A1expression, with higher SF-1 levels being associated with increased adrenal cell proliferation and tumorigenesis. In adrenocortical tumor cells, POD-1 binds to the SF-1 E-box promoter region, decreasing SF-1 expression. However, the modulation of

9. Proteases virais: importantes alvos terapêuticos de compostos peptideomiméticos
Proteases catalyze the hydrolysis of peptide bonds of proteins and peptides to produce smaller peptides and free amino acids. These enzymes are involved in physiologic processes such as blood coagulation and cellular death, and are related to life cycle of several viruses, such as hepatitis C, dengue, and AIDS. These features make most of proteases very impo

10. Use of the heteroduplex mobility assay and cell sorting to select genome sequences of the CCR5 gene in HEK 293T cells edited by transcription activator-like effector nucleases
Engineered nucleases such as zinc finger nucleases (ZFN) and transcription activator-like effector nucleases (TALEN) are one of the most promising tools for modifying genomes. These site-specific enzymes cause double- strand breaks that allow gene disruption or gene insertion, thereby facilitating genetic manipulation. The major problem associated with this

11. Resistance of cervical adenocarcinoma cells (HeLa) to venom from the scorpion Centruroides limpidus limpidus
Background : The venom of Centruroides limpidus limpidus (Cll) is a mixture of pharmacologically active principles. The most important of these are toxic proteins that interact both selectively and specifically with different cellular targets such as ion channels. Recently, anticancer properties of the venom from other scorpion species have been described.

12. Interação de oncoproteínas virais E6 e E7 de HPV16/18 com alvos celulares potenciais para o desenvolvimento de estratégias terapêuticas. / Interaction of E6 and E7 viral oncoproteins of HPV16/18 with potential cellular targets to the development of therapeutic strategies.
O potencial oncogênico do papilomavírus humano (HPV) baseia-se na capacidade das oncoproteínas virais E6 e E7 alterarem o ciclo celular, levando à imortalização e malignidade das células. O importante papel das oncoproteínas na progressão tumoral e na interação com inúmeros alvos celulares tem relevância em estudos para o desenvolvimento de vaci
