Fuel Oxidation under the Control of Mitochondrial Shape and Dynamics
By Erin L Seifert & György Hajnoczky, the EMBO Journal News & Views
How mitochondrial shape and substrate specific metabolism are related has been a difficult question to address.
Here, new work by Ngo et al (2023) reports that mitochondrial shape—long versus fragmented—determines the activity of beta oxidation of long-chain fatty acids, supporting a novel role for mitochondrial fission products as
beta oxidation hubs.
Magdalena Bachmann Awarded Postdoctoral Fellowship from AIRC
January 2023
Magdalena Bachmann received a postdoctoral fellowship from the Italian Association for Cancer Research (AIRC) to study the role of B-cell receptor (BCR) signaling in germinal center lymphomas in regulation of mitochondrial dynamics and metabolism, as well as metabolic mechanisms of resistance to BCR pathway inhibitors.
Pruthvi Gowda Awarded Postdoctoral Fellowship from the ChadTough Foundation January 2023
Pruthvi Gowda is received a postdoctoral fellowship from the ChadTough defeat DIPG foundation to investigates the mechanism and functional consequences of dietary lipids in lineage specification and tumor growth in oncohistone gliomas.
More Metabolism!
By James A. Olzmann, Nika N. Danial, Molecular Cell
To celebrate our Focus Issue, we asked a selection of researchers working on different aspects of metabolism what they are excited about and what is still to come. They discuss emerging concepts, unanswered questions, things to consider, and technologies that are enabling new discoveries, as well as developing and integrating approaches to drive the field forward.
Massachusetts Life Sciences Center funding to support a Metabolomics Facility at Dana-Farber
Dana-Farber Cancer Institute
The Massachusetts Life Sciences Center is awarding Dana-Farber Cancer Institute a $1.82 million grant titled, Mass Spectrometry Metabolomics Solutions for Highly Scalable Integrated OMics: Charting Metabolic Contributions to Disease Development and Therapeutic Outcomes.
A Mitochondrial Power Play in Lymphoma
By Ralph J. DeBerardinis, Cancer Cell Previews
Deregulated energetics is a hallmark of malignancy, but metabolic heterogeneity among individual tumors is unknown. A study by Caro et al. in this issue of Cancer Cell demonstrates that a subset of lymphomas is defined by reliance on mitochondrial energy generation and is selectively killed when this pathway is impaired.
A BAD Portion of Glucose Can be Good for Inflamed Beta Cells
By Christian Frezza, Nature Metabolism News & Views
Exposure to high glucose under inflammatory conditions is detrimental to insulin-secreting beta cells in the pancreas. Fu and colleagues describe a metabolic axis that decreases production of the 'danger molecule’ nitric oxide and improves the survival of beta cells exposed to an inflammatory milieu, thus paving the way to new interventions for diabetes.

Diffuse Large B-Cell Lymphomas are metabolically Heterogeneous
Cancer Discovery Research Watch
Diffuse large B-cell lymphomas (DLBCL) are aggressive tumors with genetic and clinical variability. DLBCL has been classified into several molecular subgroups based on transcriptional profiling, suggesting that different pathogenic mechanisms and therapeutic targets may exist within this disease.
When BAD Is Good for ꞵ Cells
By Louis H. Philipson, Cell Metabolism Previews
BAD, a proapoptotic member of the Bcl-2 family of proteins, is regulated by phosphorylation. A recent study (Danial et al., 2008) suggests a phosphorylation-state-dependent bifunctional role of BAD in the regulation of glucose-stimulated insulin secretion and
ꞵ cell mass.
In Epilepsy, BAD Is Not Really Bad
By Luca Scorrano, Neuron
Proper neuronal electrical signaling is crucial for coordinated activity of the brain: when this is malfunctioning, epileptic seizures, defined as a ‘‘transient occurrence of signs and/or symptoms due to abnormal excessive or synchronous neuronal activity in the brain’’ (Fisher et al., 2005), can arise.
