Cetoacidosis diabética como debut de diabetes mellitus inmunomediada en paciente en tratamiento con inhibidores de checkpoint

Los inhibidores de checkpoint (ICP) son anticuerpos usados en inmunoterapia contra el cáncer. Uno de sus blancos de acción es el receptor de muerte celular programada-1 (PD-1), el cual es importante para mantener la tolerancia inmunitaria. Sin embargo, este mecanismo se asocia a riesgo de eventos adver...

Cell cycle related long non-coding RNAs as the critical regulators of breast cancer progression and metastasis

Biol. Res; 56 (), 2023
Cell cycle is one of the main cellular mechanisms involved in tumor progression. Almost all of the active molecular pathways in tumor cells directly or indirectly target the cell cycle progression. Therefore, it is necessary to assess the molecular mechanisms involved in cell cycle regulation in tumor ce...

Knockout of caspase-7 gene improves the expression of recombinant protein in CHO cell line through the cell cycle arrest in G2/M phase

Biol. Res; 55 (), 2022
BACKGROUND: Chinese hamster ovary cell line has been used routinely as a bioproduction factory of numerous biopharmaceuticals. So far, various engineering strategies have been recruited to improve the production efficiency of this cell line such as apoptosis engineering. Previously, it is reported that t...

Speckle type POZ adaptor protein (SPOP) and its role in cancer

Rev. colomb. cancerol; 25 (3), 2021
Abstract Proteasomal degradation is an essential regulatory mechanism for cellular homeostasis maintenance. The speckle-type POZ adaptor protein (SPOP) is part of the ubiquitin ligase E3 cullin-3 RING-box1 complex, responsible for the ubiquitination and proteasomal degradation of biomolecules involved in...

Juniperus communis extract induces cell cycle arrest and apoptosis of colorectal adenocarcinoma in vitro and in vivo

Braz. j. med. biol. res; 54 (10), 2021
Juniperus communis (JCo) is a well-known traditional Chinese medicinal plant that has been used to treat wounds, fever, swelling, and rheumatism. However, the mechanism underlying the anticancer effect of JCo extract on colorectal cancer (CRC) has not yet been elucidated. This study investigated the anti...

Estudos funcionais e biológicos associados à interação de DUSP3 com a proteína HNRNPC1/C2

A regulação da fosforilação/desfosforilação das proteínas é o eixo central de muitas cascatas de sinalização. A fosfatase DUSP3, constituída apenas por um único domínio catalítico, desempenha papéis fundamentais na proliferação e senescência celular. Nas células HeLa, submetidas ao est...

Efeitos da 5-iodotubercidina em linhagens de melanoma humano parentais e resistentes ao inibidor de BRAF

O melanoma é responsável por menos de 5% dos cânceres de pele, porém, 95% das mortes ocorrem devido a ocorrência de metástases. O melanoma metastático é refratário às terapias convencionais e rapidamente adquire resistência às terapias como as oncogene-dirigidas, como o inibidor de BRAF, da v...

Arsenic trioxide induces cell cycle arrest and affects Trk receptor expression in human neuroblastoma SK-N-SH cells

Biol. Res; 51 (), 2018
BACKGROUND: Arsenic trioxide (As2O3), a drug that has been used in China for approximately two thousand years, induces cell death in a variety of cancer cell types, including neuroblastoma (NB). The tyrosine kinase receptor (Trk) family comprises three members, namely TrkA, TrkB and TrkC. Various studies...

Effects of karanjin on cell cycle arrest and apoptosis in human A549, HepG2 and HL-60 cancer cells

Biol. Res; 48 (), 2015
BACKGROUND: We have investigated the potential anticancer effects of karanjin, a principal furanoflavonol constituent of the Chinese medicine Fordia cauliflora, using cytotoxic assay, cell cycle arrest, and induction of apoptosis in three human cancer cell lines (A549, HepG2 and HL-60 cells). RESULTS: MT...

Arctiin blocks hydrogen peroxide-induced senescence and cell death though microRNA expression changes in human dermal papilla cells

Biol. Res; 47 (), 2014
BACKGROUND: Accumulating evidence indicates that reactive oxygen species (ROS) are an important etiological factor for the induction of dermal papilla cell senescence and hair loss, which is also known alopecia. Arctiin is an active lignin isolated from Arctium lappa and has anti-inflammation, anti-micro...
