Introduction

Chromatin reader component of the NuA4 histone acetyltransferase (HAT) complex, a complex involved in transcriptional activation of select genes principally by acetylation of nucleosomal histones H4 and H2A (PubMed:12963728, PubMed:14966270). Specifically recognizes and binds acylated histone H3, with a preference for histone H3 diacetylated at 'Lys-18' and 'Lys-27' (H3K18ac and H3K27ac) or histone H3 diacetylated at 'Lys-14' and 'Lys-27' (H3K14ac and H3K27ac) (PubMed:29437725, PubMed:29900004, PubMed:30071723). Also able to recognize and bind crotonylated histone H3 (PubMed:30071723). May also recognize and bind histone H3 succinylated at 'Lys-122' (H3K122succ); additional evidences are however required to confirm this result in vivo (PubMed:29463709). Plays a key role in histone variant H2AZ1/H2A.Z deposition into specific chromatin regions: recognizes and binds H3K14ac and H3K27ac on the promoters of actively transcribed genes and recruits NuA4-related complex to deposit H2AZ1/H2A.Z (PubMed:29437725). H2AZ1/H2A.Z deposition is required for maintenance of embryonic stem cell (By similarity).

Glioma Amplified Sequence 41 (GAS41) is a chromatin-associated protein that belongs to the YEATS domain family of proteins and is frequently amplified in various tumors. However, its biological function and carcinogenic mechanism in gliomas are not fully understood. In this study, we revealed that GAS41 was upregulated in human glioma tissues and cell lines, and higher expression of GAS41 was significantly associated with poor clinical prognosis. Genetic depletion and chemical inhibition of GAS41 remarkably inhibited glioma cell proliferation and metastasis abilities and induced cellular apoptosis. Furthermore, functional annotation identified that GAS41 was involved in stimulating the expression of membrane protein ITGA4 to activate the downstream PI3K/Akt/mTOR signaling pathway in glioma cell lines. In addition, we synthesized and evaluated a series of small molecules targeting the GAS41 YEATS domain, which yielded effective anti-proliferative activities in glioma cells. Molecular docking revealed that these compounds bound to the GAS41 YEATS domain pocket in a manner similar to Compounds 9 and 3b, providing a structural basis for exploring the selective inhibition of GAS41 as part of an essential molecular framework. Overall, our study illustrates the crucial role of GAS41 in glioma progression and the malignant phenotype and suggests that targeting GAS41 may be a promising therapeutic treatment strategy for gliomas.

BACKGROUNDRepeat leiomyoma occurrence or even reintervention is common after myomectomy. Little is known about the factors related to repeat interventions.OBJECTIVEThis study aimed to determine the frequency of leiomyoma-related reintervention after an initial laparoscopic or abdominal myomectomy and to analyze both clinical and molecular risk factors for reinterventions. Another objective was to define the frequency of clonally related tumors from repeat operations.STUDY DESIGNThis retrospective cohort study included 234 women who had undergone laparoscopic or abdominal myomectomy in 2009 to 2014. Information on repeat leiomyoma-related interventions as well as on other clinical factors was collected from medical records after a median follow-up time of 11.4 years (range 7.9-13.8 years) after the index procedure. The effect of clinical risk factors on the risk of reintervention was analyzed by the Kaplan-Meier estimator and the Cox proportional hazards model. For molecular analyses, we examined the mutation profiles of 133 formalin-fixed paraffin-embedded leiomyoma samples from 33 patients with repeat operations. We screened the tumors for the 3 primary leiomyoma driver alterations-mediator complex subunit 12 mutations, high mobility group AT-hook 2 overexpression, and fumarate hydratase-deficiency-utilizing Sanger sequencing and immunohistochemistry. To further assess the clonal relationship of the tumors, we executed whole-exome sequencing for 52 leiomyomas from 21 patients who exhibited the same driver alteration in tumors obtained from multiple procedures.RESULTSReintervention rate at 11.4 years after myomectomy was 20% (46/234). Number of leiomyomas removed at the index myomectomy was a risk factor (hazard ratio 1.21; 95% confidence interval 1.09-1.34). Age at index myomectomy (hazard ratio 0.94; 95% confidence interval 0.89-0.99) and postoperative parity (hazard ratio 0.23; 95% confidence interval 0.09-0.60) were protective factors. Molecular characterization of tumors from index and nonindex operations confirmed a clonal relationship of the tumors in 3/33 (9%) patients. None of the leiomyomas harboring a mediator complex subunit 12 mutation-the most common leiomyoma driver-were confirmed clonally related. Fumarate hydratase-deficiency was detected in repeat leiomyomas from 3/33 (9%) patients. All these patients harbored a germline fumarate hydratase mutation, which is distinctive for the hereditary leiomyomatosis and renal cell cancer syndrome. Finally, we identified 3 (3/33; 9%) patients with 2 tumors each displaying somatic mutations in a recently identified novel leiomyoma driver gene, YEATS domain-containing protein 4. All YEATS domain-containing protein 4 mutations were different and thus the tumors were not clonally related.CONCLUSIONOur study shows that reintervention is common after surgical myomectomy. Uterine leiomyomas typically develop independently, but some share a clonal origin. Repeat leiomyoma occurrence may be due to genetic predisposition, such as a germline fumarate hydratase mutation. Distinct somatic YEATS domain-containing protein 4 mutations identified in multiple leiomyomas from the same patient indicate a possible role for YEATS domain-containing protein 4 in repeat leiomyomas.

Histone acylation plays a pivotal role in modulating gene expression, ensuring proper neurogenesis and responsiveness to various signals. Recently, the evolutionary conserved YAF9, ENL, AF9, TAF41, SAS5 (YEATS) domain found in four human paralogs, has emerged as a new class of histone acylation reader with a preference for the bulkier crotonyl group lysine over acetylation. Despite advancements, the role of either histone crotonylation or its readers in neurons remains unclear. In this study, we employed Drosophila melanogaster to investigate the role of ENL/AF9 (dENL/AF9) in the nervous system. Pan-neuronal dENL/AF9 knockdown not only extended the lifespan of flies but also enhanced their overall fitness during aging, including improved sleep quality and locomotion. Moreover, a decreased activity of dENL/AF9 in neurons led to an up-regulation of catalase gene expression which combined with reduced levels of malondialdehyde (MDA) and an enhanced tolerance to oxidative stress in aging flies. This study unveiled a novel function of histone crotonylation readers in aging with potential implications for understanding age-related conditions in humans.
