In Caenorhabditis elegans embryos, paternally provided organelles, including mitochondria, are eliminated by a process of selective autophagy called allophagy, the mechanism by which mitochondrial DNA is inherited maternally. However, it remains unclear how paternal organelles are recognized and targeted for

The epidermis regenerates continually to maintain a protective barrier at the body's surface composed of differentiating keratinocytes. Maturation of this stratified tissue requires that keratinocytes undergo wholesale organelle degradation upon reaching the outermost tissue layers to form compacted, anucleate cells.

Interleukin-7 and interleukin-7 receptor are essential for normal T-cell development and homeostasis, whereas excessive interleukin-7/interleukin-7 receptor-mediated signaling promotes leukemogenesis. The protein kinase, casein kinase 2, is overexpressed and hyperactivated in cancer, including T-cell acute lymphoblastic leukemia. Herein, we show that

Tumor necrosis factor (TNF) is an important mediator that triggers onset of autoimmune diseases and exerts its biological effects by interacting through two receptors, TNFR1 (also known as TNFRSF1A) and TNFR2 (also known as TNFRSF1B). TNFR2 signaling has significant potential
Alberto Granzotto et al.
Aging, 11(16), 6336-6357 (2019-08-31)
Although aging is considered to be an unavoidable event, recent experimental evidence suggests that the process can be counteracted. Intracellular calcium (Ca2+i) dyshomeostasis, mitochondrial dysfunction, oxidative stress, and lipid dysregulation are critical factors that contribute to senescence-related processes. Ceramides, a
Norbert Braun et al.
Scientific reports, 5, 13450-13450 (2015-08-26)
Tumor cells can adapt to a hostile environment with reduced oxygen supply. The present study aimed to identify mechanisms that confer hypoxia resistance. Partially hypoxia/reoxygenation (H/R)-resistant proximal tubular (PT) cells were selected by exposing PT cultures to repetitive cycles of
Marit Wiersma et al.
Cells, 9(5) (2020-05-14)
Atrial fibrillation (AF), the most common, progressive tachyarrhythmia is associated with serious complications, such as stroke and heart failure. Early recognition of AF, essential to prevent disease progression and therapy failure, is hampered by the lack of accurate diagnostic serum

BMC cancer, 20(1), 526-526 (2020-06-07)
Effectiveness of L-asparaginase administration in acute lymphoblastic leukemia treatment is mirrored in the overall outcome of patients. Generally, leukemia patients differ in their sensitivity to L-asparaginase; however, the mechanism underlying their inter-individual differences is still not fully understood. We have
