- Bipolar disorder is a highly heritable psychiatric disorder; genome-wide association studies of bipolar disorder have yielded over 60 risk loci harboring common variants. To harness the information contained in rare loss-of-function (LOF) variants, holding promise for informing on the underlying biology, we performed a variant burden analysis for bipolar disorder using gene-based aggregation of LOF variants in whole-genome sequencing data from Iceland (4,197 cases, more than 200,000 controls) and the UK Biobank (1,881 cases, 426,622 controls). We found that HECTD2 was associated with bipolar disorder and confirmed it using the Bipolar Exome dataset. Meta-analysis with Bipolar Exome also revealed that LOF variants in AKAP11 were associated with bipolar disorder. Both associations with bipolar disorder are new, but AKAP11 has previously been associated with psychosis and schizophrenia. The products of AKAP11 and HECTD2 interact with GSK3β, a protein inhibited by lithium, the most effective mood stabilizer available to treat bipolar disorder. - Source: PubMed

However, the underlying mechanisms remain largely undetermined. Unbiased proteomic screening is performed to identify the potential regulators of lenvatinib resistance in HCC. Patient-derived organoids, patient-derived xenograft mouse models, and DEN/CCl induced HCC models are constructed to evaluate the effects of HECTD2 both in vitro and in vivo. HECTD2 is found to be highly expressed in lenvatinib-resistant HCC cell lines, patient tissues, and patient-derived organoids and xenografts. In vitro and in vivo experiments demonstrated that overexpression of HECTD2 limits the response of HCC to lenvatinib treatment. Mechanistically, HECTD2 functions as an E3 ubiquitin ligase of KEAP1, which contributes to the degradation of KEAP1 protein. Subsequently, the KEAP1/NRF2 signaling pathway initiates the antioxidative response of HCC cells. Lactylation of histone 3 on lysine residue 18 facilitates the transcription of HECTD2. Notably, a PLGA-PEG nanoparticle-based drug delivery system is synthesized, effectively targeting HECTD2 in vivo. The NPs achieved tumor-targeting, controlled-release, and biocompatibility, making them a promising therapeutic strategy for mitigating lenvatinib resistance. This study identifies HECTD2 as a nanotherapeutic target for overcoming lenvatinib resistance, providing a theoretical basis and translational application for HCC treatment. - Source: PubMed

Dong RunyuFei YaoHe YirenGao PengZhang BoZhu MenglinWang ZhixiongWu LongfeiWu ShuaiWang XiaomingCai JuanChen ZhiqiangZuo Xueliang - Peritoneal metastasis (PM) is a common metastasis site and death cause of gastric cancer, which is a complex biological process, but there is currently a lack of effective prediction and treatment targets. In this study, we first analyzed the differential gene expression of gastric cancer patients with or without peritoneal metastasis, and identified the HECT domain E3 ubiquitin protein ligase 2 (HECTD2) as the core gene of PM in gastric cancer. The current study shows that the role of HECTD2 in tumor is contradictory. In this study, our results show that the low expression of HECTD2 indicates that the survival rate of overall survival (OS), progression-free survival (PFS), disease-specific survival (DSS), and disease-free survival (DFS) are better, and can be used as an important component of prognostic indicators. In addition, through pathway enrichment analysis, we found that HECTD2 was mainly involved in metastasis related pathways such as extracellular matrix remodeling and cell adhesion in gastric cancer, and high expression of HECTD2 could activate epithelial-mesenchymal transition (EMT) metastasis related pathways in gastric cancer. In regulating the metastasis of gastric cancer cells, HECTD2 can also change the surrounding microenvironment, induce the enrichment of interstitial components and build an immune microenvironment conducive to tumor progression, while patients with low expression of HECTD2 may be more likely to benefit from immunotherapy. In conclusion, HECTD2 may be a novel biomarker for the diagnosis and prognosis of peritoneal metastasis of gastric cancer, providing basis for the mechanism of peritoneal metastasis of cancer and clinical medication. - Source: PubMed

Gong LibaoHuang JiayiBai XueSong LinHang JunjieGuo Jinfeng - Function of HECTD2 in renal cell carcinoma malignant progression is undefined. Molecular mechanism behind anti-cancer effects of veratric acid (VA) from traditional Chinese medicine (TCM) is underexplored. The Cancer Genome Atlas was leveraged to study HECTD2 expression in renal cell carcinoma and its relationship with histological grading. Kaplan-Meier survival analysis was performed. HECTD2 expression was detected in cancer cells and tissues via qRT-PCR and immunohistochemistry. GPX4 and SLC7A11 expression in tumor samples with high or low HECTD2 expression was examined by immunohistochemistry, cell viability by CCK8, cell proliferation by colony formation assay, lipid ROS and mitochondrial superoxide levels by flow cytometry, Fe and MDA content by assay kits, and GPX4 and SLC7A11 proteins by western blot. SeeSAR software screened TCM small molecule compounds with highest affinity to HECTD2, confirmed with cellular thermal shift assay. VA IC was measured by CCK8. Xenograft model was developed and treated with VA. Tumor size and weight were monitored, with immunohistochemistry to detect HECTD2 expression in tumors and assess ferroptosis-related markers. HECTD2 was overexpressed in tumor tissues and cells, which positively correlated with histological grading. HECTD2 depletion inhibited cell vitality and proliferation, raised intracellular lipid ROS, mitochondrial superoxide, Fe, and MDA. HECTD2 was a target with highest VA affinity. In vitro and vivo experiments concurred that VA treatment hindered malignancy of renal cell carcinoma and enhanced its susceptibility to ferroptosis. HECTD2 supports ferroptosis resistance in renal cell carcinoma, but VA, through its targeting of HECTD2, initiates ferroptosis, showcasing its anti-cancer efficacy. - Source: PubMed
