AZIN1-dependent polyamine synthesis accelerates tumor cell cycle progression and impairs effector T-cell function in osteosarcoma

open access: yesCell Death and Disease
Osteosarcoma, the most prevalent malignant bone tumor among adolescents, frequently exhibits limited responsiveness to immunotherapy, a challenge attributed to poorly understood underlying mechanisms.

Functional Characterization of the P‐Type ATPases ATP13A3 and ATP13A4 as Plasma Membrane Polyamine Transporters [PDF]

open access: yesFASEB J
ATP13A3 and ATP13A4 mediate the plasma membrane uptake of the polyamines, putrescine and spermidine, in an ATP‐dependent manner. ATP13A3 is broadly expressed across human tissues, whereas ATP13A4 is expressed at relatively high levels in the brain and lung.

Natural product‐derived TRPM7 channel inhibitors in neurological injury: Mechanisms, pharmacological potential and translational challenges

open access: yesBritish Journal of Pharmacology, EarlyView.
Disruption of intracellular ionic homeostasis is a convergent pathological feature across diverse neurological injuries and disorders, including ischaemic and haemorrhagic stroke, hypoxic–ischaemic brain injury, traumatic brain injury, epilepsy and brain tumour.

Ammonia Accumulation Drives Intervertebral Disc Degeneration by Triggering Ammonia‐Induced Cell Death Through Lysosome–Mitochondria Crosstalk

open access: yesCell Proliferation, EarlyView.
Mechanical strain disrupts the lysosome‐mitochondria axis via GLS1‐mediated ammonia toxicity, causing NP cell death and ECM breakdown in IVDD. CB839‐mediated GLS1 inhibition effectively rescues cellular homeostasis and alleviates disc degeneration.

Dysregulation of SIRT1, polyamines and miRNA editing in cancer and aging

open access: yesAmino Acids
Interest in RNA editing has emerged in molecular medicine due to its widespread dysregulation and therapeutic potential. Its regulatory mechanisms in governing non-coding RNAs, especially microRNAs (miRNAs) remain largely unresolved. Emerging evidence in

S‐Adenosylmethionine (SAM) hydrolases counter increased SAM epimerisation in thermophilic archaea

open access: yesThe FEBS Journal, EarlyView.
S‐Adenosyl‐l‐methionine (SAM) is a vital enzyme cofactor. Epimerisation at the sulfonium centre of biologically active (SS,SCα)‐SAM is driven by heat, yielding biologically inactive (RS,SCα)‐SAM. Here, two novel archaeal SAM hydrolases from the thermophilic Sulfolobus acidocaldarius and the halophilic Haloferax volcanii are shown to cleave (RS,SCα)‐SAM.

Epigenetic and Metabolic Changes That Drive Trained Immunity in Response to Microbes and Vaccines

open access: yesImmunology, EarlyView.
This graphical abstract illustrates how microbial products, vaccines and microbial metabolites activate pattern‐recognition receptor signalling, inducing metabolic rewiring and epigenetic remodelling. These changes establish long‐lasting trained immunity through the functional reprogramming of haematopoietic progenitors and innate immune cells, thereby

Differences in Polyamine Levels between 'Kyoho,' 'Campbell Early' and 'Muscat Bailey A' Grapes with Differing Features of Berry Drop

open access: yes, 2002
A comparative study was conducted of berry dropping and changes in polyamine levels in 'Kyoho,' 'Campbell Early' and 'Muscat Bailey A' grapes. Berry dropping occurred first in 'Muscat Bailey A' grapes, peaking 6 days after full bloom.
