CYAD-01, an autologous NKG2D-based CAR T-cell therapy, in relapsed or refractory acute myeloid leukaemia and myelodysplastic syndromes or multiple myeloma (THINK): haematological cohorts of the dose escalation segment of a phase 1 trial. (PubMed, Lancet Haematol) - P1/2 | "Treatment with a multiple CYAD-01 infusion schedule without preconditioning is well tolerated and shows anti-leukaemic activity, although without durability outside of patients bridged to allogeneic HSCT. These phase 1 data support the proof-of-concept of targeting NKG2D ligands by CAR T-cell therapy. Further clinical studies with NKG2D-based CAR T-cells are warranted, potentially via combinatorial antigen targeted approaches, to improve anti-tumour activity."

The CmNAC64-CmWRKY48 module regulates homogalacturonan (HG) degradation to promote the softening of oriental melon. (PubMed, Plant Physiol Biochem) - "Integrating promoter motif analysis and co-expression networks, we uncovered two transcription factors-CmNAC64 and CmWRKY48 were linked to softening. Y1H, Dual-LUC, and transient expression assays collectively verified that the nuclear-localized transcription factor CmNAC64 directly activates CmPG2 and CmACO1, and also positively regulates the expression of CmACS1 by activating CmWRKY48, thereby facilitating the fruit softening process of oriental melon through a multi-level coordinated regulatory network."

TCR inhibitory molecule as a promising allogeneic NKG2D CAR-t cell approach. (ASCO 2018) - "The TIM reduces GvHD yet does not interfere with NKG2D-CAR mediated anti-tumor activity offering an attractive allogenic CAR T cell therapy. The clinical development of CYAD-101 will be further pursued in a phase I trial to assess the safety and clinical activity of multiple doses administered with standard chemotherapy in patients with unresectable metastatic colorectal cancer."

Impact of alpha-ketoglutarate treatment on enhancing vase life of chrysanthemum by enhancing antioxidant systems and suppressing ethylene biosynthesis. (PubMed, Sci Rep) - "Furthermore, AKG application suppressed ethylene (ETH) production by downregulating the activities of 1-aminocyclopropane-1-carboxylic acid synthase (ACS) and oxidase (ACO), which was further confirmed by the reduced expression of CmACS1 and CmACO1 genes. Collectively, these findings demonstrate that 5 mM AKG represents a sustainable and eco-friendly strategy for enhancing the postharvest quality and longevity of cut chrysanthemums by integrating metabolic stability with hormonal regulation."

The mechanistic insights into sex determination of melon: integrating environmental factors, hormones and genetic regulation. (PubMed, Plant Sci) - "At the genetic level, a core regulatory module has been identified, centered on the ethylene biosynthesis genes CmACS7 and CmACS11, and the zinc-finger transcription factor CmWIP1. Their spatiotemporal interactions, along with recently characterized regulators such as CmCRC, CmETR1, CmEIN2, CmLHP1, CmCPR5 and CmHB40, fine-tune the development of male, female, and bisexual flowers. This study provides a foundational framework for understanding melon sex determination and supports future efforts to artificially create melon germplasms with diverse sex types."

A Genome Wide Association Study of Problematic Sexual Behaviour (WCPG 2025) - "PRS analyses revealed significant associations of PSB with ASB, OCS and anxiety (all p < 0.05, with limited variance explained: NkR2 = 0.3 - 0.7%), but not with the other phenotypes examined... Analyses of All PSB vs Controls did not find any significant single marker associations at the genome-wide level (5e-8), but found 12 suggestive SNPs (<1e-5) in 10 genomic loci. A cluster of these SNPs mapped to an area on Chr17; this association was consistently observed across analysis and ancestry groupings. The gene-based test did not find any genome-wide significant association (p = 0.05/18904 genes = 2.645e-6), but DDX42 on Chr17 was the top hit (p = 3.0275e-06) with several other suggestive genes observed (<1e-5)."

Downregulation of MICA/MICB improves cell persistence and clinical activity of NKG2DL CAR T-cells in patients with relapsed or refractory acute myeloid leukemia or myelodysplastic neoplasia. (PubMed, Leukemia) - P1, P1/2 | "CYAD-02 presented an higher engraftment and an improved clinical activity (17% objective response rate) compared to CYAD-01 (no objective response). Altogether, our data provide proof of principle that knock-down of MICA/B can enhance CAR T-cell persistence and efficacy while maintaining a good safety profile."

Identification and Functional Exploration of the ALKBH Gene Family in Oriental Melon Fruit Ripening. (PubMed, Int J Mol Sci) - "The transient overexpression (OE) of CmALKBH8 in oriental melon led to the increased expression of the ethylene synthesis genes CmACS1, CmACS2, and CmACO1. In summary, the ethylene-regulated gene CmALKBH8 may participate in oriental melon fruit ripening regulation by modulating the methylation levels of ethylene synthesis-related genes. These findings help us better understand how m6A methylation regulates melon ripening."

Larger GWAS with homogeneity in antidepressant treatments are needed to explore the genetic variation associated with ADR and realize the potential of PGS to contribute to specific response subtypes."

Association Between Polygenic Scores for Lithium Response and Lithium Augmentation Outcomes in Unipolar Depression (WCPG 2023) - "We observed a significant positive association between LIR-PS and ΔHAMD (beta=-1.04 , CI=[-1.86,-0.23], p=0.012, R2=2.24%) but not between LIR-PS and categorical response (OR=1.11, CI=[0.87,1.41], p=0.414, NKR2 =0.32%) at a p-value threshold of PT=0.05. After excluding a subgroup with suboptimal lithium levels, LIR-PS was even stronger associated with symptom improvement during LA (beta=-1.23, CI=[-2.14,-0.32], p=0.008 at PT=0.05) explaining up to 3.16 % of variance in ΔHAMD. Although the discovery GWAS of lithium response in BD still has a modest sample size, our preliminary results suggest that LI-PS may also be useful in the prediction of LA outcomes in unipolar depression."

Overcoming target-driven fratricide for CAR-T cell therapy (SITC 2018) - P1/2; "The broad Phosphoinositol-3- Kinase inhibitor (LY294002) was added following the two-day transduction. CYAD-01 CAR T cells are currently part of the phase I THINK clinical trial (NCT03018405) where clinical objective responses have been observed. Conclusions These results indicate that target-driven fratricide can be overcome using clinically relevant approaches where technologies such as gene-editing may be more challenging."

Tackling fratricide to manufacture clinical grade NKG2D-CAR T cells for cancer therapy (ESMO 2018) - P1/2; "Background: T cells bearing a chimeric antigen receptor (CAR) T-cell consisting of the fusion of the NKG2D NK receptor with the intracellular domain of CD3zeta (CYAD-01) can recognize eight stress ligands expressed in a large variety of cancers... Inclusion of the PI-3K inhibitor LY294002 into the manufacturing process was the first strategy used as an initial effort focused upon blunting the activity of the CAR T cells... Together, these results indicate that when fratricide is an issue preventing clinical development, CAR T cells can be efficiently manufactured through PI-3K inhibition and antibody mediated receptor blockade."
