In conclusion, our study provides compelling evidence that apigenin inhibits liver cancer progression and elucidates its mechanism of action in regulating lipid metabolism. Specifically, we find that apigenin suppresses the progression of HCC cells by downregulating genes involved in lipid metabolism. Additionally, our results indicate that KDM1A acts as a downstream target of apigenin in the inhibition of lipid metabolism in HCC. These findings offer experimental support for the potential use of apigenin as a therapeutic agent for liver cancer, highlighting its relevance in future clinical applications.

Therefore, in this review, we will systematically summarize how proteins involved in the transcriptional corepressor complex, various post-translational modifications, and metabolites act as regulatory factors for LSD1 activity.

In colorectal liver metastasis (CLM), TAM morphology correlates with prognosis, with smaller TAMs (S-TAMs) conferring a more favorable prognosis than larger TAMs (L-TAMs)...The inflammatory stimuli promoted by TNFα induced the increased expression of riboflavin transporter SLC52A3 and LSD1 in M2 macrophages. The modulation of the riboflavin-LSD1 axis represents a potential target for reprogramming TAM subtypes, paving the way for promising anti-tumor therapeutic strategies.

In this work, we designed PCPA-entinostat conjugates for selective cancer cell targeting. PCPA-entinostat conjugate 12 with a 4-oxybenzyl group linker released entinostat in the presence of LSD1 in in vitro assays and selectively inhibited the growth of cancer cells in preference to normal cells, suggesting the potential of PCPA-entinostat conjugates as novel anticancer drug delivery small molecules.

Unlike in GIP-dependent primary bilateral macronodular adrenal hyperplasia, KDM1A genetic variations are not the cause of GIPR expression in somatotroph pituitary adenomas. Recurrent KDM1A haploinsufficiency, more frequently observed in GIPR-expressing adenomas, could be responsible for decreased KDM1A function resulting in transcriptional derepression on the GIPR locus.

The xenograft assays also showed that DUSP4 overexpression-promoted ESCC tumor growth in vivo and LC3II and LSD1 protein expression in tumor tissues were reversed by rapamycin or anisomycin. Overall, DUSP4 inhibits Bcl2-Beclin1-autophagy signal transduction through the negative regulation of JNK, thus suppressing autophagic death and the autophagic degradation of LSD1 in ESCC, by which DUSP4 promotes ESCC carcinogenesis.

The results of this experiment demonstrated that the treatment of breast cancer cells with tamoxifen reduces the expression of VEGF and KDM1A by increasing miR-329. The treatment therefore reduces angiogenesis, and thus its anti-tumor effects are applied.

LSD1 was shown to participate in an intriguing antiviral mechanism, where it activates endolysosomal interferon-induced transmembrane protein 3 (IFITM3) via demethylation, leading endocytosed HCV virions to degradation. Our study proposes that HCV-mediated LSD1 oscillations over countless viral life cycles throughout chronic HCV infection may promote epigenetic changes related to HCV-induced hepatocarcinogenesis.

Importantly, KDM1A-KO or -KD enhanced the efficacy of ERβ agonist LY500307, and the combination of KDM1A inhibitor (KDM1Ai) NCD38 with ERβ agonist synergistically reduced the cell viability, colony formation, and invasion of OCa cells...Our results demonstrate that KDM1A regulates ERβ expression/functions, and its inhibition improves ERβ mediated tumor suppression. Overall, our findings suggest that KDM1Ai and ERβ agonist combination therapy is a promising strategy for OCa.

Collectively, CHMP4A is not only a novel positive predictor for prognosis in BC but also a stimulator of CD8+ T-lymphocyte infiltration regulated by the LSD1/IFNβ pathway. This study suggests that CHMP4A may be a novel target for improving the effectiveness of immunotherapy in patients with BC.

The primary endpoint is ORR per RECIST 1.1; secondary endpoints include rate of ≥ grade 3 toxicities, PFS, OS and DoR. Exploratory endpoints include host inflammatory cytokine and immune profile, and epigenomic and genomic analysis of tumor and peripheral blood samples.

Lastly, loss of KDM1A markedly reduced 53BP1 DNA repair foci, implying the involvement of KDM1A in the DNA damage response. Overall, our results indicate that KDM1A impacts CRC progression in several non-overlapping ways, and therefore it represents a promising epigenetic target to prevent tumor relapse.

Importantly, 3-MA or MCC950 addition obviously reversed the inhibitory effects of LSD1 silencing on the proliferation, migration, invasion, and EMT of hypopharyngeal cancer cells. To sum up, LSD1 silencing could restrain the progression of hypopharyngeal cancer cells by inducing autophagy and pyroptosis.

We included 186 patients: 108 patients (70.6 %) had a classic pathological GH response after oral glucose load, whereas 45 patients (29.4%) displayed a paradoxical rise of GH concentrations. Patients with a paradoxical response displayed higher IGF-1 levels (360 ± 111.8 % above ULN vs. 309.8 ± 107.3 %, p= 0.0130) and less invasive and smaller tumors (14.5 ± 5.58 mm vs.

In this review, we compiled what is known about the LSD1 function in various sarcomas, to determine where knowledge is lacking and to find what theme emerge to characterize how LSD1 is a key molecular driver in bone and soft tissue sarcoma. We further discuss the current clinical landscape for the development of LSD1 inhibitors and where sarcomas have been included in early clinical trials.

The expression patterns of the KDMs in bladder cancer highlight a high mutation complementarity and a negative correlation between over-expression and hypomethylation level closely related with the prognosis, immune infiltration and drug sensitivity.

Tranylcypromine-based covalent LSD1 inhibitors have demonstrated anti-tumor activity but are associated with undesirable off-target effects, such that only 2 non-covalent LSD1 inhibitors are in clinical trials. The most active of these analogues, compound 48, exhibited potent and selective mixed reversible inhibition of LSD1 (IC = 0.58 μM) and significantly increased global H3K4me2 in NB cells. In addition, combination treatment with 48 and bortezomib in NB cells results in a synergistic effect.
