Dammarenediol II enhances etoposide‐induced apoptosis by targeting O‐GlcNAc transferase and Akt/GSK3β/mTOR signaling in liver cancer

open access: yesMolecular Oncology, EarlyView.
Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...

Equivariant K-theory, generalized symmetric products, and twisted Heisenberg algebra

open access: yes, 2002
For a space X acted by a finite group $\G$, the product space $X^n$ affords a natural action of the wreath product $\Gn$. In this paper we study the K-groups $K_{\tG_n}(X^n)$ of $\Gn$-equivariant Clifford supermodules on $X^n$.

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

open access: yesMolecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

The spatial organization of sphingofungin biosynthesis in Aspergillus fumigatus and its cross-interaction with sphingolipid metabolism

open access: yesmBio
Sphingofungins are sphinganine analog mycotoxins acting as inhibitors of serine palmitoyl transferases, enzymes responsible for the first step in the sphingolipid biosynthesis.

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer

open access: yesMolecular Oncology, EarlyView.
Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability. Figure created and edited with BioRender.com.

Aporphine Alkaloids from the Chinese Tree

open access: yesNatural Product Communications, 2007
Three new oxygenated noraporphine alkaloids were isolated from the bark of the Chinese tree Neolitsea aurata var. paraciculata. The new compounds, (+)-11-methoxynorcassythicine, (+)-11-methoxynorneolitsine, (+)-11-methoxynorboldine, were isolated along ...

Checkpoint blockade and the stem‐like T cell trade‐off

open access: yesMolecular Oncology, EarlyView.
Stem‐like T cells are key to the success of programmed cell death protein 1 (PD1) blockade, as they sustain long‐term anti‐tumor response by continuously generating effector CD8+ T cells. However, how these cells are maintained in cancer is not fully understood. Hor et al.

The palmitoyl-CoA ligase Fum16 is part of a Fusarium verticillioides fumonisin subcluster involved in self-protection

open access: yesmBio
Fusarium verticillioides produces the mycotoxin fumonisin B1 (FB1), which disrupts sphingolipid biosynthesis by inhibiting ceramide synthase and affects the health of plants, animals, and humans. The means by which F. verticillioides protects itself from
