4 days ago · On a cellular level, cellulite results from fat cells enlarging and pushing against the skin’s connective tissue, which comprises collagen and elastin fibres. In women, these fibres form a vertical pattern, creating “chambers” that the expanding fat cells can protrude into, causing that signature bumpy appearance.
5 days ago · The hereditary nature of cancer at the cellular level explains why alterations have been found in both the genetic and the epigenetic codes in tumour cells. The number of alterations seen in the coded programs increases as tumours progress to more advanced stages.
4 days ago · An emerging model of intelligence finds flexible problem-solving capabilities at the cellular level and beyond – and it threatens to upend not just biology and genetics, but medicine, AI and ...
2 days ago · At the cellular level, we also described that, paradoxically, the cell-cell interactions between stromal and epithelial cells can either promote regeneration or maintain quiescence, depending on the number of direct cell-cell contacts between both populations (Cordero-Espinoza et al., Cell Stem Cell 2021).
2 days ago · Researchers' success in pinpointing a drug therapy inside the body, at the cellular level, proved to be a highly efficient delivery method that could be used to treat other injuries.
5 days ago · An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
5 days ago · Ubiquitylation affects cellular process by regulating the degradation of proteins (via the proteasome and lysosome), coordinating the cellular localization of proteins, activating and inactivating proteins, and modulating protein–protein interactions.
