The TRPM7 channel kinase regulates store‐operated calcium entry [PDF]

The Journal of Physiology, 2017
Key points Pharmacological and molecular inhibition of transient receptor potential melastatin 7 (TRPM7) reduces store‐operated calcium entry (SOCE). Overexpression of TRPM7 in TRPM7−/− cells restores SOCE. TRPM7 is not a store‐operated calcium channel. TRPM7 kinase rather than channel modulates SOCE.

Untersuchung TRPC-modulierender Gestagene und Proteine [PDF]

, 2008
In the first part of this study, we have identified the two steroid hormones progesterone and norgestimate as novel TRPC channel blockers. Both substances blocked TRPC-mediated Ca2+ influx with micromolar activities in fluorometric measurements.

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

FEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Store operated calcium entry in NIH-3T3 cells

The Journal of Medical Investigation, 2009
)bythe patch clamp technique. Therefore, thapsigargin-induced SOCE is a useful approach to investigatemechanisms of SOCE.Immortal NIH3T3 cells have been establishedfrom the embryonic NIH Swiss mice fibroblasts. TheNIH-3T3 cell is a useful cell line for investigationof transformation, stress fiber formation, or feedercells of keratinocytes.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining

Molecular Oncology, EarlyView.
IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.

Aging, sarcopenia and store-operated calcium entry [PDF]

Cell Cycle, 2011
While overall bodily functions decrease with aging, the impact on some specific tissues produces life-changing consequences. For instance, skeletal muscle reduction in size and especially in function has tremendous negative implications for the individual, family and society.1,2 The aging-related loss of muscle mass and strength leads to reduced ...

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

Molecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

Zinc oxide nanoparticle disruption of store-operated calcium entry in a muscarinic receptor signaling pathway [PDF]

, 2010
The influences of ZnO nanoparticles on cellular responses to activation of muscarinic receptors were studied in Chinese hamster ovary cells expressing the human M3 muscarinic acetylcholine receptor.
