Palmitoylation by ZDHHC family members regulate B-cell lymphoma growth

open access: hybridInternational Journal of Biological Macromolecules
The ZDHHC palmitoyl transferase family consists of 24 members, of which several have been linked to the development of cancer. We previously showed that inhibition of ZDHHC11 decreased growth of several B-cell lymphoma subtypes. In this study, we evaluated the effect of protein palmitoylation on the proteome in general and investigated expression and ...

SMAD4 Palmitoylation Drives a Metabolic‐Transcriptional Circuit to Promote Tumorigenesis and Confers Radiosensitivity in Pancreatic Cancer

open access: yesAdvanced Science, EarlyView.
This study identifies palmitoylation as a novel regulatory modification of SMAD4, mediated by ZDHHC22/APT2. It activates fatty acid synthesis, creating a self‐reinforcing SMAD4–FASN–palmitate feedback loop that drives pancreatic cancer growth and enhances radiotherapy sensitivity.

Palmitic Acid Promotes Antiviral Innate Immunity via ZDHHC20‐Mediated CMPK2 Palmitoylation

open access: yesAdvanced Science, EarlyView.
Metabolites have important functions in innate immune activation and regulation. Wang et al. uncover metabolic regulation of antiviral immunity through CMPK2 palmitoylation, which regulates CMPK2 mitochondrial localization and is promoted by ZDHHC20 but reversed by PPT1, inhibition of which antagonizes viral infection in mice.

Deregulation of ceramide synthases affect ZDHHC expression, protein S-palmitoylation and the lipid network

open access: green
Approximately one-third of all proteins localize to biological membranes, which not only maintain cellular integrity but also serve as platforms for signaling. Many membrane-resident or membrane-associated proteins depend on translocation to specialized microdomains, as well as on posttranslational modifications (PTMs) for their function.

ZDHHC18‐Mediated Palmitoylation of ORF3a Promotes SARS‐CoV‐2 Pathogenesis by Antagonizing TRIM16‐Mediated Ubiquitination and Proteasomal Degradation

open access: yesAdvanced Science, EarlyView.
Palmitoylation by ZDHHC18 blocks ORF3a K27‐linked ubiquitination mediated by TRIM16, thereby preventing its proteasomal degradation and strengthening viral pathogenesis. Targeting palmitoylation through a pharmacological inhibitor (2‐BP), a competitive inhibitory peptide (OPIP), or adenovirus‐mediated knockdown of ZDHHC18 expression presents a ...

ZDHHC17‐Mediated CDK4 Palmitoylation Drives Cell Cycle Progression and Orchestrates Cancer Immune Surveillance

open access: yesAdvanced Science, EarlyView.
ZDHHC17 palmitoylates CDK4, which together with TRAF6‐mediated ubiquitination, drives cell cycle progression and immune surveillance, revealing a rational combination of CDK4 inhibitors with immune checkpoint blockers for ZDHHC17‐driven cancers. ABSTRACT Uncontrolled cell cycle progression is a hallmark of cancer, tightly regulated by both intrinsic ...

ABHD17C‐Mediated S‐Depalmitoylation of BCL6B Enhances CD24 Transcription to Resist Macrophage Phagocytosis in Pancreatic Cancer

open access: yesAdvanced Science, EarlyView.
ABHD17C‐mediated depalmitoylation of BCL6B at Cys442 blocks its nuclear import and triggers ubiquitin‐dependent degradation, attenuating transcriptional repression of the anti‐phagocytic signal CD24. This mechanism enables pancreatic cancer cells to evade macrophage phagocytosis and fosters an immunosuppressive microenvironment.

Comprehensive analysis of key palmitoylation-modifying enzymes in clear cell renal cell carcinoma: implications for prognosis and therapy

open access: yesCancer Cell International
Background Palmitoylation, a key post-translational modification, plays a crucial role in tumor progression, yet its landscape in clear cell renal cell carcinoma (ccRCC) remains poorly characterized.

Protein palmitoylation: an emerging regulator of inflammatory signaling and diseases

open access: yesFrontiers in Immunology
Protein palmitoylation is a reversible lipid modification in which palmitoyl esters are covalently attached to cysteine residues of proteins. It controls various cellular physiological processes and alters protein stability, conformation, localization ...

The Growth Supporting Role of ZDHHC11 Is Linked to the MEF2B–BCL6 Regulatory Circuit in Burkitt Lymphoma

open access: yesInternational Journal of Cancer, EarlyView.
MEF2B and BCL6 have established functions in germinal center B‐cell biology and lymphomagenesis. The mechanism of MEF2B deregulation and its significance for cell survival in Burkitt lymphoma however remain unclear. This study highlights MEF2B as a crucial transcription factor in Burkitt lymphoma and suggests ZDHHC11 as an upstream regulator of MEF2B ...
