Using specific monoclonal antibodies, we investigated the distribution of post-translational modified Tyr- and Glu-tubulins during interphase of the primitive flagellate Entosiphon sulcatum. Immunofluorescence studies of simultaneously permeabilized and fixed cells revealed that microtubular structures comprising Ca(2+)-labile subpellicular and flagellar MTs and Ca(2+)-stable MTs in the siphon ...
alphaB-Crystallin, one of the small heat-shock proteins, is constitutively expressed in various tissues including the lens of the eye. It has been suggested that alphaB-crystallin provides lens transparency but its function in nonlenticular tissues is unknown. It has been reported that alphaB-crystallin is involved in the stabilization and the regulation of cytoskeleton, such as intermediate fi...
Birefringence of the mitotic apparatus (MA) and its change during mitosis in sea urchin eggs were quantitatively determined using the birefringence detection apparatus reported in the preceding paper (Hiramoto el al., 1981, J. Cell Biol. 89:115-120). The birefringence and the form of the MA are represented by five parameters: peak retardation (delta p), through retardation (delta t), interpolar...
The relationship between alpha tubulin detyrosination and microtubule (MT) stability was examined directly in cultured fibroblasts by experimentally converting the predominantly tyrosinated MT array to a detyrosinated (Glu) array and then assaying MT stability. MTs in mouse Swiss 3T3 cells displayed an increase in Glu immunostaining fluorescence approximately 1 h after microinjecting antibodies...
Muir-Torre syndrome (MTS) is a rare disorder characterized by the presence of at least one sebaceous gland neoplasm and at least one visceral malignancy. Sebaceous adenomas, sebaceous carcinomas, and sebaceomas (sebaceous epitheliomas) are all characteristic glandular tumors of MTS. The most common visceral malignancies associated with MTS are colorectal, followed by genitourinary. These viscer...
Muir-Torre syndrome (MTS) is a rare autosomal dominant inherited genodermatosis that is considered to be a phenotypic subtype of hereditary nonpolyposis colorectal cancer (HNPCC), commonly referred to as Lynch syndrome. We describe the clinical course of a 57-year-old female patient with MTS. She has a confirmed HMSH2 mutation. Recently she presented with two nodular lesions. Histologic examina...
Multivariate time series (MTS) data are ubiquitous in science and daily life, and how to measure their similarity is a core part of MTS analyzing process. Many of the research efforts in this context have focused on proposing novel similarity measures for the underlying data. However, with the countless techniques to estimate similarity between MTS, this field suffers from a lack of comparative...
We have discovered several novel features exhibited by microtubules (MTs) in migrating newt lung epithelial cells by time-lapse imaging of fluorescently labeled, microinjected tubulin. These cells exhibit leading edge ruffling and retrograde flow in the lamella and lamellipodia. The plus ends of lamella MTs persist in growth perpendicular to the leading edge until they reach the base of the lam...
Microtubule-associated protein 4 (MAP4) promotes MT assembly in vitro and is localized along MTs in vivo. These results and the fact that MAP4 is the major MAP in nonneuronal cells suggest that MAP4's normal functions may include the stabilization of MTs in situ. To understand MAP4 function in vivo, we produced a blocking antibody (Ab) to prevent MAP4 binding to MTs. The COOH-terminal MT bindin...
Microtubules (MTs) have been implicated to function in the change of cell shape and intracellular organization that occurs during myogenesis. However, the mechanism by which MTs are involved in these morphogenetic events is unclear. As a first step in elucidating the role of MTs in myogenesis, we have examined the accumulation and subcellular distribution of posttranslationally modified forms o...
