background: in recent years, adipose tissue, due to the stem cells contained within, has found a new special place in laboratory and clinical applications. these adipose‑derived stem cells (adscs) have the same characteristics of bone marrow mesenchymal stem cells (bmscs). although bone marrow (bm) is not easily accessible and its procurements may be painful, most patients possess excess fat wh...

Microtubule protein purified from rat brain by published procedures contains nucleic acid and carbohydrate contaminants. Microtubule protein isolated from the soluble fraction of rat brain homogenates by a new procedure contains no covalently bound amino sugars and no more than 0.2% neutral sugar, but does contain covalently bound phosphate. Total phosphate analysis of rat brain microtubule pro...

Human EB1 was originally cloned as a protein that interacts with the COOH terminus of adenomatous polyposis coli (APC). Interestingly, this interaction is often disrupted in colon cancer, due to mutations in APC. EB1 also interacts with the plus-ends of microtubules and targets APC to microtubule tips. Since APC is detected on the kinetochores of chromosomes, it has been hypothesized that the E...

Microtubules, the active filaments with tubular shapes, play important roles in a wide range of cellular functions, including structural supports, mitosis, cytokinesis, and vesicular transport, which are essential for the growth and division of eukaryotic cells. Finding properties of microtubules is one of the main concerns of scientists. This work helps to obtain mechanical properties of m...

LKB1, a tumor suppressor gene mutated in the Peutz-Jeghers syndrome, encodes a serine/threonine protein kinase. Recent biochemical studies have shown that LKB1 activates 14 AMP-activated protein kinase-related kinases including MARKs (microtubule-associated protein/microtubule affinity-regulating kinases) that regulate microtubule dynamics. Here we show in vitro that LKB1 phosphorylates and act...
