However, the induction of p57 KIP2 expression in response to TGF-β is likely to be the most important downstream event to suppress hematopoietic cell proliferation (Scandura et al. 2004). In astrocytes, TGF-β suppresses cell proliferation by inducing p15 INK4B expression in a Smad3-dependent manner (Rich et al. 1999).
Cellular proliferation is the fundamental biological process by which cells undergo division to produce new cells. There are five key methods for measuring cell proliferation—indirect measures, cell cycle markers, dye dilution assays, DNA synthesis methods, and live-cell imaging—which we covered in an article last year. This year, we …
1. Introduction. FGFs are a family of cell-signaling proteins produced by different types of cells. The first members of the fibroblast growth factor (FGF) family (FGF1 and FGF2) were discovered in the 1970s and were initially named acidic and basic FGF, respectively [].FGFs can affect the proliferation of multiple cells, including endothelial …
Proliferation of cells is an important process that may be seen in action in many different settings. Cancer, in which cells divide uncontrollably and create tumours, is characterised by aberrant cell proliferation. Conditions like ageing, in which tissues and organs become less efficient at repairing and regenerating themselves, are linked to ...

Solar lentigo (SL) is a representative photoaging skin disorder. Alteration of the main epidermal constituent cells—keratinocytes and melanocytes—in relation to the photoaged dermal environment or chemokine/cytokine network is suggested as its pathogenesis. Among these, we focused on monocyte chemoattractant protein-1 (MCP …
Given their importance in atherogenesis, the role of normal and oxidised lipoproteins in regulating smooth muscle cell proliferation has been extensively studied (see reference ). Several normal lipoprotein fractions stimulate smooth muscle cell proliferation either by acting as a nutrient [90] or a specific mitogen [89, 91] .
Microbial gene expression depends not only on specific regulatory mechanisms, but also on cellular growth because important global parameters, such as abundance of mRNAs and ribosomes, could be growth rate dependent. Understanding these global effects is necessary to quantitatively judge gene regulation. In the last few years, …

Cell proliferation refers to the processes that result in an increase in the number of cells and is necessary for general development. ... They are important cells to the body (e.g. red cells that transport oxygen to cells around the body) and therefore have to continue being replaced when the old ones die. However, because they are unable to ...
The core cell cycle machinery operating in the cell nucleus orchestrates cell division. The key components of this machinery are proteins called cyclins that bind, activate and provide substrate specificity to their associated catalytic partners, the cyclin-dependent kinases (CDKs) 1–4.Cell cycle progression can be divided into four phases: gap 1 (G1), DNA …
The interaction of EPO and EPOR triggers the activation of several signaling pathways including PI3K/AKT and MAPK. They are known to be important regulators of the differentiation, proliferation, and cell survival of erythroid cells. More information is emerging about their role in the protection of non-hematopoietic tissues …
Consequences of coupling between transcription and mRNA degradation to the growth rate for cell phenotypes and cell cycle. a The phenotypic response of a daughter cell to a regulatory stimulus can be conditioned by the expression of the corresponding genes in the mother cell. If the daughter cell needs to down-regulate a …

Types of Cancer. Cancer can result from abnormal proliferation of any of the different kinds of cells in the body, so there are more than a hundred distinct types of cancer, which can vary substantially in their behavior and response to treatment. The most important issue in cancer pathology is the distinction between benign and malignant tumors (Figure 15.1).
Decreased viability of tumor cells may reflect two important physiological processes, namely the arrest of proliferation associated with disturbances in cellular metabolism or actual cell death.
