Novel tankyrase inhibitors suppress TDP-43 aggregate formation

Transactive response DNA-binding protein of 43 kDa (TDP-43) abnormally forms aggregates in certain subtypes of frontotemporal lobar degeneration (FTLD) and in amyotrophic lateral sclerosis (ALS). The pathological forms of TDP-43 have reported to be associated with poly(ADP-ribose) (PAR), which regulates the properties of these aggregates. A recent study has indicated that tankyrase, a member of the PAR polymerase (PARP) family, regulates...
