Hedgehog pathway permissive conditions allow generation of immortal cell lines from granule cells derived from cancerous and non-cancerous cerebellum [PDF]

open access: yesOpen Biology, 2019
Cerebellar granule cell progenitors (GCPs) undergo proliferation in the post-natal cerebellum that is dependent on sonic hedgehog (SHH) signalling. Deregulated SHH signalling leads to type 2 medulloblastoma (MB).

Waiting time distributions in hybrid models of motor-bead assays: A concept and tool for inference [PDF]

open access: yesInt. J. Mol. Sci. 2023, 24(8), 7610, 2023
In single-molecule experiments, the dynamics of molecular motors are often observed indirectly by measuring the trajectory of an attached bead in a motor-bead assay. In this work, we propose a method to extract the step size and stalling force for a molecular motor without relying on external control parameters.

Computation of Biological Assays [PDF]

open access: yesNature, 1946
IN microbiological assays of essential amino-acids, and of members of the vitamin B2 complex other than riboflavin and nicotinic acid, it is usually found that when the mean responses are plotted against either the dose or the logarithm of the dose, a non linear relationship is obtained.
