Glycosyltransferase Inhibitors:  Synthesis of d-threo-PDMP, l-threo-PDMP, and Other Brain Glucosylceramide Synthase Inhibitors from d- or l-Serine

, 2016
The synthesis of enantiomerically pure (1S,2S)-1-phenyl-2-decanoylamino-3-N-morpholino-1-propanol (l-threo-PDMP) (1a) from l-serine, and the enantiomer (1R,2R)-1-phenyl-2-decanoylamino-3-morpholino-1-propanol (d-threo-PDMP] (1b) from d-serine is reported.

Role of p53 serine 46 in p53 target gene regulation [PDF]

, 2011
The tumor suppressor p53 plays a crucial role in cellular growth control inducing a plethora of different response pathways. The molecular mechanisms that discriminate between the distinct p53-responses have remained largely elusive.

PANoptosis in the pathogenesis of myelodysplastic syndromes

Molecular Oncology, EarlyView.
PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...

The study of a new and specific proline cleaving peptidase from bovine serum [PDF]

, 2003
Prolyl oligopeptidase is a serine peptidase characterised by oligoendopeptidase activity. Definitive evidence for the discrete biological role of prolyl oligopeptidase remains unknown, though its role in the maturation and degradation of peptide hormones

Cancer cell‐intrinsic type 1 interferon: production, signaling, and outcomes within sex‐biased, female malignancies

Molecular Oncology, EarlyView.
The cell‐autonomous roles of interferon type 1 vary based on duration and intensity. While acute, robust signaling results in cancer cell cytotoxic effects, sustained, low‐level signaling is associated with tumor‐promoting effects. This review summarizes current research of IFN‐1 in cancer and within the clinical setting, with an emphasis on female ...

ADP‐ribosylation: An emerging regulator of the epigenome

Molecular Oncology, EarlyView.
ADP‐ribosylation has emerged as a dynamic epigenetic signaling mechanism that modifies histones and chromatin‐associated proteins. Through coordinated PARylation and MARylation, it integrates with other histone modifications to regulate chromatin structure, transcription factor activity, and gene expression, influencing genome function and disease ...

Castration‐resistant prostate cancer cells are addicted to the high activity of cyclin‐dependent kinase 2

Molecular Oncology, EarlyView.
We show that emergence of castration‐resistant prostate (CRPC) is associated with significant upregulation of cyclins that positively regulate cyclin‐dependent kinase 2 (CDK2) and concomitant downregulation of CDK4 cyclins. This renders CRPC cells dependent on the high activity of CDK2, and CDK2 inhibitors synergistically sensitize CRPC cells to both ...

Malarial proteases and host cell egress: an 'emerging' cascade. [PDF]

, 2008
Malaria is a scourge of large swathes of the globe, stressing the need for a continuing effort to better understand the biology of its aetiological agent. Like all pathogens of the phylum Apicomplexa, the malaria parasite spends part of its life inside a
