Silent voltage-gated K+ (Kv) subunits interact with Kv2 subunits and primarily modulate the voltage dependence of inactivation of these heterotetrameric channels. Both Kv2 and silent Kv subunits are expressed in the mammalian nervous system, but little is known about their expression and function in sensory neurons. This study reports the presence of Kv2.1, Kv2.2, and silent subunit Kv6.1, Kv8.1, Kv9.1, Kv9.2, and Kv9.3 mRNA in mouse dorsal root ...

Thyroid hormones (THs) stimulate and coordinate a wide range of processes to ensure normal development, mainly by binding of the most active TH 3,5,3'-triiodothyronine (T3) to nuclear receptors resulting in changes in gene transcription. Local TH action is monitored at three distinct levels by different types of regulators: transmembrane transporters (TH influx and efflux), deiodinases (TH activation and inactivation) and nuclear receptors (TH ...

Asparaginase (ASNase) is an important anti-leukaemic drug in the treatment of childhood acute lymphoblastic leukaemia (ALL) and non-Hodgkin lymphoma (NHL). A substantial proportion of patients develop hypersensitivity reactions with anti-ASNase neutralising antibodies, resulting in allergic reactions or silent inactivation (SI), and characterised by inactivation and rapid clearance of ASNase. We report results of a prospective, real-time ...

The diversity of the voltage-gated K+ (Kv) channel subfamily Kv2 is increased by interactions with auxiliary beta-subunits and by assembly with members of the modulatory so-called silent Kv subfamilies (Kv5-Kv6 and Kv8-Kv9). However, it has not yet been investigated whether these two types of modulating subunits can associate within and modify a single channel complex simultaneously. Here, we demonstrate that the transmembrane beta-subunit KCNE5 ...

Mutations in SCN2A, a gene encoding the voltage-gated sodium channel Nav1.2, have been associated with a spectrum of epilepsies and neurodevelopmental disorders. Here, we report the phenotypes of 71 patients and review 130 previously reported patients. We found that (i) encephalopathies with infantile/childhood onset epilepsies (≥3 months of age) occur almost as often as those with an early infantile onset (<3 months), and are thus more ...

In this thesis, I aimed to define the dynamics and the mechanisms that orchestrate the reversal of stable gene silencing during reprogramming of somatic cells into induced pluripotent stem cells (iPSCs). I used X chromosome reactivation as a paradigm to better understand the reversal of silent chromatin. In addition, my goal was also to define the gene regulatory logic of mammalian pre- implantation development and reprogramming, as well as to ...

A methodology for kinetic modeling of atom transfer radical polymerization is developed allowing to calculate the monomer conversion, the fraction of polymer molecules having end group functionality, the full molar mass distribution (MMD) of the dormant polymer and the number, mass, and z based average molar mass of the dead and dormant polymer. The developed methodology is based on an extension of the method of moments and allows an accurate ...
