HDAC10 (Histone Deacetylase 10)

HDAC3 was found to associate with TYK2 and contributed to activation of the TYK2-STAT1-BCL2 signaling pathway in T-ALL cells. Our results highlight the effectiveness of the combination of chidamide and chemotherapy in the treatment of T-ALL patients and suggest that HDAC3 can act as a potential novel therapeutic target to inhibit the TYK2-STAT1-BCL2 signaling pathway in T-ALL.

This study highlights the need for rigorous validation of results. In our case, two orthogonal testing methods were not sufficient to catch all the confounding factors involved in measurement of HDAC inhibition, and a third approach was required to identify the actual inhibition of 9 against HDAC9 and 11.

However, mechanistic understanding of HDAC10's selective function, especially in shaping the tumor microenvironment, remains limited. We advocate for targeted investigations using isoform-selective inhibitors, functional in vivo studies, and immune subset profiling to clarify HDAC10's therapeutic relevance in colorectal cancer.

In addition, we assessed the anti-proliferative activity these compounds against a panel of four human solid tumor cell lines. To evaluate their selectivity, non-cancerous kidney cell lines (LLC-PK1 and VERO) were employed to determine the effects of these compounds on normal cell proliferation.

This study provides the first atomic-resolution framework for HDAC10's catalysis and selectivity, resolving long-standing mechanistic ambiguities. By identifying critical interactions governing substrate recognition and turnover, our work establishes a foundation for designing isoform-specific HDAC10 inhibitors, offering strategic avenues to target its roles in disease.

This study revealed the significance of HDAC10 in TME, therapy efficacy, and clinical prognosis in CRC, offering novel insights for therapeutic advancements in CRC.

In conclusion, periplocin, as a novel natural compound, exhibits significant anti-leukemia activity, highlighting its potential as a promising therapeutic candidate for leukemia treatment. The findings contribute to the growing interest in natural compounds as innovative solutions for addressing unmet clinical needs in hematological malignancies.

To this end, the dual HDAC6/10 inhibitor tubastatin A and a ring-opened analog were connected via well-established PROTAC linkers to pomalidomide and phenylglutarimides as cereblon recruiters...Importantly, AP1 neither degraded HDAC1/8 (class I) and HDAC4/7 (class IIa), nor induced histone H3 hyperacetylation, thereby confirming its selectivity for class IIb HDACs. Due to its low cytotoxicity against hematological and solid cancer cell lines, AP1 represents a valuable tool compound for the chemical knockdown of class IIb HDACs.

Concurrently, the combined regimen enhanced their respective anticancer effects by inhibiting the key genes HDAC10 and BCL-xL. Taken together, venetoclax combined with chidamide presents a potent anticancer strategy in preclinical models of t-FL and merits further exploration in clinical trials to validate its effectiveness and safety for treating t-FL.

Furthermore, ZMF-25 exhibits remarkable therapeutic potential with no obvious toxicity in vivo and good pharmacokinetics. In summary, these observations indicate that ZMF-25 is a novel and potent triple-targeting PAK1/HDAC6/HDAC10 inhibitor, which is expected to provide a novel and effective strategy for TNBC treatment.

HDAC10 controls the MYC-POLD1 axis to maintain the processivity of DNA replication and genome integrity. This mechanistically defined "HDAC10ness" may be exploited as treatment option for lymphoid malignancies.

However, methodological rigor in future studies is essential to enhance the reliability and validity of findings. Comprehensive understanding of baicalein's effects on miRNA expression holds promise for developing novel cancer treatment strategies.
