The cell multiplied by duplicating all its contents followed by cellular division. Mobile technology is the technology used for cellular communication. Peptides bind to GPCRs to induce signaling cascades that alter cellular and synaptic activity. Symptoms are related to alterations in membrane potential and cellular metabolism. Growth factors comprise the second major set of candidates of epigenetic regulators of cellular differentiation. Ionizing radiation works by damaging the DNA of cancerous tissue leading to cellular death. Paraspeckles are dynamic structures that are altered in response to changes in cellular metabolic activity. The phenomena described above are dependent on changes at the cellular and molecular levels. Radiolocation in cellular telephony uses base stations. Millimeter wave antennas are smaller than the large antennas used in previous cellular networks. Growth factors are important for regulating a variety of cellular processes. Exposure to chemical agents that cause DNA damage also induces cellular aggregation. These react with and damage a number of cellular and extracellular elements. HBx appears to dysregulate a number of cellular pathways. Neurons are highly specialized for the processing and transmission of cellular signals.
