Taspase1, the mixed lineage leukemia and TFIIAalpha-beta cleaving protease, enables cell proliferation and permits oncogenic initiation. Here, we show its critical role in cancer maintenance and thus offer a new anticancer target. Taspase1 is overexpressed in primary human cancers, and deficiency of
Taspase 1 (TASP1) cleaves the mixed-lineage leukemia (MLL) and transcription factor (TF) IIA families of nuclear proteins to orchestrate various biological processes. TASP1 is not a classical oncogene, but assists in cell proliferation and permits oncogenic initiation through cleavage of MLL and
Proteolysis is not only a critical requirement for life, but the executing enzymes also play important roles in numerous pathological conditions, including cancer. Therefore, targeting proteases is clearly relevant for improving cancer patient care. However, to effectively control proteases, a
The "oncogene addiction" concept refers to the dependence of cancer cells on the function of the oncogenes responsible for their transformed phenotype, while the term "non-oncogene addiction" has been introduced to define the exacerbated necessity of the normal function of non-mutated genes. In this
Lysosomes are acidic, dynamic organelles that supervise catabolism, integrate signaling cascades, and tune cellular trafficking. Moreover, the loss of their integrity may jeopardize cell viability. In cancer cells, lysosomes are qualitatively and quantitatively modified for the tumor's own benefit.
BACKGROUND
Heat shock protein 90 (HSP90) has a key role in the maintenance of the cellular proteostasis. However, HSP90 is also involved in stabilisation of oncogenic client proteins and facilitates oncogene addiction and cancer cell survival. The development of HSP90 inhibitors for cancer treatment
