Transport of intracellular cargos by multiple microtubule motor proteins is believed to be a common and significant phenomenon in vivo, yet signatures of the microscopic dynamics of multiple motor systems are only now beginning to be resolved. Understanding these mechanisms largely depends on determining how grouping motors affect their association with microtubules and stepping rates, and henc...

Texas-Red-asialoorosomucoid (ASOR) fluorescence-sorted early and late endocytic vesicles from rat liver were subjected to proteomic analysis with the aim of identifying functionally important proteins. Several Rab GTPases, including Rab1a, were found. The present study immunolocalized Rab1a to early and late endocytic vesicles and examined its potential role in endocytosis. Huh7 cells with stab...

We recently demonstrated that dynein and kinesin motors drive multiple aspects of endosomal function in mammalian cells. These functions include driving motility, maintaining morphology (notably through providing longitudinal tension to support vesicle fission), and driving cargo sorting. Microtubule motors drive bidirectional motility during traffic between the endoplasmic reticulum (ER) and G...

OBJECTIVES To determine anaemia prevalence and related factors in pregnant women (PW), post partum women (PPW) and non pregnant women (NPW) in a remote mountainous district. METHODS A cross-sectional survey was conducted in 2001. All PW, all PPW within 6 months of delivery and a random number of NPW equivalents to the number of PW in each commune were selected. Hemoglobin (Hb) was measured us...

Inhibition of human chymase by the serpins alpha1-antichymotrypsin (ACT) and alpha1-proteinase inhibitor (PI) at pH 8.0 produces a complex stable to dissociation by SDS/dithiothreitol and a second product, hydrolyzed/inactivated serpin. The first product is the presumed trapped acyl-enzyme complex typical of serpin inhibition, and the second is the result of a concurrent substrate-like reaction...

RET-fusion was reported contribute about 2% of acquired resistance mechanisms EGFR/ALK-TKIs. Selective RET inhibitor pralsetinib demonstrated impressive improvement survival in patients with RET+ aNSCLC the I/II ARROW study. However, efficacy after to EGFR/ALK-TKIs only by case, and strategy overcome has not been fully investigated. This multicenter, retrospective, real-world data analysis enro...

Purpose: Aberrations in genetic sequences encoding the tyrosine kinase receptor RET lead to oncogenic signaling that is targetable with anti-RET multikinase inhibitors. Understanding the comprehensive genomic landscape of RET aberrations across multiple cancers may facilitate clinical trial development targeting RETExperimental Design: We interrogated the molecular portfolio of 4,871 patients w...

Purpose: Broad, hybrid capture–based next-generation sequencing (NGS), as a clinical test, uses less tissue to identify more clinically relevant genomic alterations compared with profiling with multiple non-NGS tests. We set out to determine the frequency of such genomic alterations via this approach in tumors in which previous extensive non-NGS testing had not yielded a targetable driver alter...
