Triple-negative breast cancer (TNBC) is notoriously difficult to treat due to the lack of targetable receptors and sometimes poor response to chemotherapy. The transforming growth factor beta (TGFβ) family of proteins and their receptors (TGFRs) are highly expressed in TNBC and implicated in chemotherapy-induced cancer stemness. Here, we evaluated combination treatments using experimental TGFR inhibitors (TGFβi), SB525334 (SB), and LY2109761 (LY) with paclitaxel (PTX) chemotherapy.

Acute myeloid leukemia (AML) is a fatal disease characterized by the accumulation of undifferentiated myeloblasts, and agents that promote differentiation have been effective in this disease but are not curative. Dihydroorotate dehydrogenase inhibitors (DHODHi) have the ability to promote AML differentiation and target aberrant malignant myelopoiesis. We introduce HOSU-53, a DHODHi with significant monotherapy activity, which is further enhanced when combined with other standard-of-care therapeutics.

Amyotrophic lateral sclerosis is the most common fatal motor neuron disease. Approximately 90% of ALS patients exhibit pathology of the master RNA regulator, Transactive Response DNA Binding protein (TDP-43). Despite the prevalence TDP-43 pathology in ALS motor neurons, recent findings suggest immune dysfunction is a determinant of disease progression in patients.

Article Synopsis
  • TDP-43 proteinopathies, such as frontotemporal lobar degeneration (FTLD) and amyotrophic lateral sclerosis (ALS), are neurodegenerative diseases where the protein TDP-43 misfolds and disrupts neuronal function.
  • Researchers created models that mimic sporadic TDP-43 proteinopathy, showing how acetylation at lysine 145 impairs TDP-43's ability to bind RNA and leads to gene mis-regulation.
  • Results indicate that this acetylation triggers harmful changes in neurons, evidenced by cognitive decline and altered gene expression related to synaptic function, mirroring characteristics seen in human FTLD cases.
