A formalization of one of the main claims of “ALS-implicated protein TDP-43 sustains levels of STMN2,a mediator of motor neuron growth and repair” by Klim et al. 2019 1

Abstract

Klim et al. claimed in previous work that the protein TDP-43 generally contributes to the transcription of STMN2 in human motor neurons. We present here a formalization of that claim, stating that all things of class “TAR DNA binding protein” that are in the context of a thing of class “human motor neuron” can generally have a relation of type “contributes to” to a thing of class “transcription of stmn2” in the same context.

Keywords

Human motor neuron TAR DNA binding protein transcription of stmn2

1. Introduction

Klim et al. [2] state that “expression of STMN2, which encodes a microtubule regulator, declined after TDP-43 knockdown and TDP-43 mislocalization as well as in patient-specific motor neurons”. We present here a formalization of the main scientific claim from this quote by using a semantic template called the super-pattern [1].

2. Formalization

Our formalization looks as follows:

CONTEXT-CLASS (“in the context of all ...”):	human motor neuron
SUBJECT-CLASS (“things of type ...”):	TAR DNA binding protein
QUALIFIER:	can generally
RELATION-TYPE (“have a relation of type...”):	contributes to
OBJECT-CLASS (“to things of type...”):	transcription of stmn2

In the context class we use the class “human motor neuron” (Q101404862) from Wikidata. In the subject class, we use the class “TAR DNA binding protein” (Q21133247) from Wikidata. In the object class we minted a new class “transcription of stmn2” that is a subclass of “transcription” (Q177900) from Wikidata and is related to the class “STMN2” (Q18036104) from Wikidata.

3. RDF code

This is our formalization as a nanopublication in TriG format:
