O que é o Ciclo Celular?
The cell cycle refers to the sequence of events occurring throughout a typical cell’s life. In eukaryotic cells, the somatic cell cycle has two…
DNA Genómico em Procariotas
The genome of most prokaryotic organisms consists of double-stranded DNA organized into one circular chromosome in a region of cytoplasm called the…
Fissão Binária
Fission is the division of a single entity into two or more parts, which regenerate into separate entities that resemble the original. Organisms in…
DNA Genómico em Eucariotas
Eukaryotes have large genomes compared to prokaryotes. To fit their genomes into a cell, eukaryotic DNA is packaged extraordinarily tightly inside…
Interfase
The cell cycle occurs over approximately 24 hours (in a typical human cell) and in two distinct stages: interphase, which includes three phases of…
Mitose e Citocinese
In eukaryotes, the cell division cycle is divided into distinct, coordinated cellular processes that include cell growth, DNA replication/chromosome…
Moléculas Reguladoras Positivas
To consistently produce healthy cells, the cell cycle—the process that generates daughter cells—must be precisely regulated. Internal…
Moléculas Reguladoras Negativas
Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a…
Cancro
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science…
Avaliando a progressão do ciclo celular de tronco neurais e as células progenitoras no desenvolvimento do cérebro do rato após estresse genotóxico
Neurons of the cerebral cortex are generated during brain development from different types of neural stem and progenitor cells (NSPC), which form a…
Acompanhamento Temporal de progressão do ciclo celular utilizando citometria de fluxo, sem a necessidade de sincronização
This protocol describes a method to permit the tracking of cells through the cell cycle without requiring the cells to be synchronized. Achieving…
Estudando a expressão de genes regulada pelo ciclo celular por dois protocolos complementares de sincronização de células
The gene expression program of the cell cycle represents a critical step for understanding cell cycle-dependent processes and their role in diseases…
