Aging and mitochondrial dysfunction in the filamentous fungus Podospora anserina
In the filamentous fungus Podospora anserina, mitochondria play a paramount role in life span control and aging. During aging, these organelles...

Aging and the programmed death phenomena
Biochemical mechanisms of the programmed death phenomena are considered at levels of unicellular organisms, mitochondria, cells, groups of cells, and...

Introduction: Regulatory processes, an emerging feature in intracellular membrane traffic
The subject of this volume is the molecular mechanism of the intracellular membrane trafficking, a central eukaryotic cell biological process. In the...

Functions of Rab GTPases in organelle biogenesis
Rab GTPases regulate diverse aspects of the biogenesis of secretory and endocytic organelles. The conformational changes that accompany GTP binding...
-
Regulation of SNARE assembly by protein phosphorylation
Protein phosphorylation is emerging as an important regulatory mechanism that controls the secretory pathway. It enables coupling between the...
-
Molecular mechanisms in clathrin-mediated membrane budding
Clathrin-coated vesicles (CCVs) form at the plasma membrane where they select cargo for endocytic entry into cells. CCVs also form at the trans-Golgi...
-
Tethering proteins in membrane traffic
In eukaryotic cells, protein secretion and the transport of materials between membrane-bounded organelles require efficient and accurate delivery of...
-
Regulation of exocytotic events by centrosome-analogous structures
Centrosomes, spindle pole bodies, and related structures, generally termed microtubule organising centres (MTOCs; Pickett-Heaps 1969), are best...
-
Energy metabolism, anti-oxidant defense and aging in Caenorhabditis elegans
Food restriction and impaired gene function by mutation or RNAi treatment can extend the lifespan of Caenorhabditis elegans considerably. In contrast...
-
Do green plants age, and if so, how?
Time-dependent ageing-like processes in green plants are discussed and compared to gerontological changes in animals and other organisms. The...

Conditional senescence in prokaryotes
Bacteria are immortal in the sense that their capacity for reproduction appears limitless as long as the environment supports growth. However, this...

Regulating membrane curvature
Membranes of living cells are subject to a variety of shape changes. Membrane deformation is essential for cell division, locomotion, organelle...

Yeast as a model for ageing and apoptosis research
Apoptosis is a form of programmed cell death with a crucial role in health and disease in metazoans. Recent findings demonstrate the existence of an...
-
Mammalian and bird aging, oxygen radicals, and restricted feeding
In this chapter, the relationship of aging with oxidative stress is reviewed. Endogenous tissue antioxidants do not determine aging because they...
-
Role of subcytotoxic stress in tissue ageing
Most commonly stress-induced premature senescence (SIPS) is defined as the long-term effects of subcytotoxic stress on proliferative cell types,...
-
Mitochondria, metabolism, and aging in yeast
Quantitative and qualitative changes in metabolism take place when the lifespan is extended in yeast either by genetic or nutritional manipulation....

Phosphoinositides and membrane traffic in health and disease
The phosphorylated derivatives of phosphatidylinositol (PtdIns) are collectively known as the polyphosphoinositides (PIs) and they were originally...

The function of Sec1/Munc18 proteins – Solution of the mystery in sight?
Members of the Sec1/Munc18 (SM) protein family form a central part of the machinery responsible for transport vesicle docking and fusion. Their...
