Recycling the Cell Cycle Cyclins Revisited
I discuss advances in the cell cycle in the 21 years since cyclin was discovered. The surprising redundancy amongst the classical cyclins (A, B, and E) and cyclin-dependent kinases (Cdk1 and Cdk2) show that the important differences between these proteins are when and where they are expressed rather than the proteins they phosphorylate. Although the broad principles of the cell cycle oscillator...
متن کاملStylalgia Revisited: Clinical Profile and Management
Introduction: Eagle’s syndrome is a constellation of signs secondary to an elongated styloid process or due to mineralization of the stylohyoid or stylomandibular ligament or the posterior belly of the digastric muscle. The syndrome includes symptoms ranging from stylalgia (i.e. pain in the tonsillar fossa, pharyngeal or hyoid region) to foreign-body sensation in the throat, cervicofacial pain,...
متن کاملThe cell cycle–apoptosis connection revisited in the adult brain
Adult neurogenesis is studied in vivo using thymidine analogues such as bromodeoxyuridine (BrdU) to label DNA synthesis during the S phase of the cell cycle. However, BrdU may also label DNA synthesis events not directly related to cell proliferation, such as DNA repair and/or abortive reentry into the cell cycle, which can occur as part of an apoptotic process in postmitotic neurons. In this s...
متن کاملThe rat estrous cycle revisited: a quantitative and qualitative analysis
The rat has been elected as the main animal model in several studies involving reproduction. However, there are scarce and conflicting data related to its estrous cycle. It comprises phases characterized by different cell types in vaginal smears (proestrus, estrus, metestrus and diestrus). Nevertheless, this classification and the time span of each phase are controversial and may induce mislead...
متن کاملCell cycle analysis and microarrays
A recent profusion of microarray analysis of gene expression during the cell division cycle raises questions as to whether statistical problems with the data analysis have been considered. Two non-scientific examples – ESP and the Bible Code – illustrate the problem. Individuals with extrasensory perception (ESP) were identified by their ability to guess pictograms in a deck of 25 cards. There ...
