Cell cycle regulators are crucial proteins and molecules that control the progression and timing of the cell cycle, ensuring proper cell division and replication. Disruptions in these regulators can lead to uncontrolled cell proliferation, contributing to cancer development.

Cell Cycle Regulators

Crucial proteins

Molecules are the smallest units of a chemical compound that retain the composition and chemical properties of that compound, formed when two or more atoms join together chemically. They play a crucial role in the structure and function of all matter, from the simplest gases to the most complex biological organisms.

Timing of the cell cycle

Cell division is a fundamental biological process where a single cell divides into two or more daughter cells, essential for growth, development, and repair in multicellular organisms. This process occurs through two main types: mitosis, which results in identical daughter cells, and meiosis, which leads to the production of gametes with half the number of chromosomes of the parent cell.

Uncontrolled cell proliferation

Cancer development, or carcinogenesis, is a multi-step process involving genetic and epigenetic changes that lead to uncontrolled cell growth and tumor formation. It is influenced by factors such as mutations, environmental exposures, and lifestyle choices, which disrupt normal cellular regulatory mechanisms.
