Revisiting the microtubule based quantum models of mind: tubulin bound GTP cannot pump microtubule coherence or provide energy for alpha <-> beta computation in stable microtubules [PDF]

open access: yes, 2003
The current paper investigates the biological models of stable brain microtubules as quantum or classical computers whose function is based on electron hopping associated with kinking of the tubulin dimer. Hameroff (1998a, 1998b, 2003a, 2003b), Tuszynski

Modeling oscillatory Microtubule--Polymerization [PDF]

open access: yes, 2002
Polymerization of microtubules is ubiquitous in biological cells and under certain conditions it becomes oscillatory in time. Here simple reaction models are analyzed that capture such oscillations as well as the length distribution of microtubules.

NF-KB protein purification from bovine spleen: Nucleotide stimulation and binding site specificity [PDF]

open access: yes, 1988
The activity of the enhancer for the κ immunoglobulin light chain gene critically depends on the presence in the nucleus of the NF-κB protein. We purified NF-κB over 50,000-fold and identified two protein species, 42 and 44 kDa, that could be eluted and ...

Transient disappearance of RAS mutant clones in plasma: A counterintuitive clinical use of EGFR inhibitors in RAS mutant metastatic colorectal cancer [PDF]

open access: yes, 2019
Genomic studies performed through liquid biopsies widely elucidated the evolutionary trajectory of RAS mutant clones under the selective pressure of EGFR inhibitors in patients with wild type RAS primary colorectal tumors. Similarly, the disappearance of

Sugar‐sensing swodkoreceptors and swodkocrine signaling

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Sugar‐sensing swodkoreceptors that trigger swodkocrine signaling. Abstract Sugars are one of the major metabolites and are essential for nucleic acid synthesis and energy production. In addition, sugars can act as signaling molecules. To study sugar signaling at the systemic level, there is an urgent need to systematically identify sugar‐sensing ...

Guanosine triphosphate cyclohydrolase I deficiency: a rare cause of hyperphenylalaninemia

open access: yesThe Turkish Journal of Pediatrics, 1999
Tetrahydrobiopterin (BH4) deficiencies are a heterogeneous group of disorders caused by a defect in two of the three enzymes involved in its biosynthesis or in the two recycling enzymes.

Protocol for structural and biochemical analyses of RhoA GTPase

open access: yesSTAR Protocols, 2021
Summary: Ras GTPases in complex with Guanosine triphosphate (GTP) or GTP analog exhibit dynamic equilibrium between two interconvertible conformations—an inactive state 1 and an active state 2.
