Hyperresponsiveness of mice deficient in plasma-secreted sphingomyelinase reveals its pivotal role in early phase of host response

Journal of Lipid Research, 2013
Plasma secretion of acid sphingomyelinase is a hallmark of cellular stress response resulting in the formation of membrane embedded ceramide-enriched lipid rafts and the reorganization of receptor complexes.

Causal Effects of Hydrophilic Bile Acids on Carfilzomib‐Related Cardiovascular Events in Multiple Myeloma: A Mendelian Randomization Study

Clinical Pharmacology &Therapeutics, Volume 119, Issue 6, Page 1494-1502, June 2026.
Carfilzomib is highly effective in the treatment of multiple myeloma, but it has been associated with cardiovascular adverse events that impact patient outcomes. Our prior global metabolomic analyses indicated an association between hydrophilic bile acids and carfilzomib‐cardiotoxicity risk, although a causal relationship remained to be determined ...

The structure and catalytic mechanism of human sphingomyelin phosphodiesterase like 3a – an acid sphingomyelinase homologue with a novel nucleotide hydrolase activity [PDF]

The FEBS Journal, 2016
Human sphingomyelinase phosphodiesterase like 3a (SMPDL3a) is a secreted enzyme that shares a conserved catalytic domain with human acid sphingomyelinase (aSMase), the enzyme carrying mutations causative of Niemann–Pick disease. We have solved the structure of SMPDL3a revealing a calcineurin‐like fold.

The Role of N6‐Methyladenosine Modification in Health and Disease

MedComm, Volume 7, Issue 6, June 2026.
N6‐methyladenosine (m6A) is the most prevalent internal RNA modification in eukaryotes, acting as a pivotal epitranscriptomic regulator of RNA metabolism. This modification plays a dual role: it maintains physiological homeostasis under normal conditions but drives disease progression when dysregulated.

Increased liver tumor formation in neutral sphingomyelinase-2-deficient mice

Journal of Lipid Research, 2018
Sphingolipids are key signaling lipids in cancer. Genome-wide studies have identified neutral SMase-2 (nSMase2), an enzyme generating ceramide from SM, as a potential repressor for hepatocellular carcinoma.

The Dual Role of Autophagy in Cancer: Mechanisms and Therapeutic Strategies

MedComm – Oncology, Volume 5, Issue 2, June 2026.
Autophagy is a conserved cellular process degrading dysfunctional organelles and protein aggregates to maintain cell homeostasis, and it exhibits context‐dependent duality in cancer. Autophagy functions as a critical tumor‐suppressive mechanism by preventing DNA damage and mutation during tumor initiation.
