Triplications and certain point mutations in the SNCA gene, encoding alpha-synuclein (α-Syn), cause Parkinson's disease (PD). Here, we demonstrate that the PD-causing A53T α-Syn mutation and elevated α-Syn expression perturb acetyl-coenzyme A (CoA) and p300 biology in human neurons and in the CNS of zebrafish and mice. This dysregulation is mediated by activation of ATP-citrate lyase (ACLY), a key enzyme that generates acetyl-CoA in the cytoplasm, via two mechanisms.

Article Synopsis
  • Autophagy is a key cellular process that breaks down damaged materials and recycles nutrients, especially important during times of starvation.
  • It plays a role in neurodegenerative diseases by removing harmful proteins and organelles, with increased autophagy showing promise in improving conditions in animal models.
  • However, factors like aging and certain genetic mutations hinder autophagy, leading to a cycle where toxic proteins accumulate more, highlighting the need for research on autophagy's role in aging and neurodegenerative disorders for potential therapies.

Autophagy is a conserved pathway where cytoplasmic contents are engulfed by autophagosomes, which then fuse with lysosomes enabling their degradation. Mutations in core autophagy genes cause neurological conditions, and autophagy defects are seen in neurodegenerative diseases such as Parkinson's disease and Huntington's disease. Thus, we have sought to understand the cellular pathway perturbations that autophagy-perturbed cells are vulnerable to by seeking negative genetic interactions such as synthetic lethality in autophagy-null human cells using available data from yeast screens.

The mechanistic target of rapamycin complex 1 (mTORC1) is a master regulator of cell growth, metabolism and autophagy. Multiple pathways modulate mTORC1 in response to nutrients. Here we describe that nucleus-cytoplasmic shuttling of p300/EP300 regulates mTORC1 activity in response to amino acid or glucose levels.

Background: and Purpose: Hereditary spastic paraplegias (HSP) are a group of clinically diverse genetic disorders that share the neurologic symptom of difficulty in walking due to progressive serious muscle weakness and spasticity in the legs. This study describes a physiotherapy program for improving the functional ability of a child diagnosed with complicated HSP and reports the treatment results.

Methods: A 10-year-old boy with complicated HSP received a physiotherapy intervention that included strengthening of the leg muscles and treadmill training for 1 h per session, three to four times a week for 6 weeks.

Background: Motor imagery training has a similar effect to that of physical training on motor performance. The objective of this study was to investigate the short-term effectiveness of motor imagery training on response inhibition using the stop signal task (SST).

Methods: Participants were divided into a physical training group (PT,  = 17), a motor imagery training group (MIT,  = 17), and a motor imagery combined with physical training group (MIPT,  = 17).

The term autophagy encompasses different pathways that route cytoplasmic material to lysosomes for degradation and includes macroautophagy, chaperone-mediated autophagy, and microautophagy. Since these pathways are crucial for degradation of aggregate-prone proteins and dysfunctional organelles such as mitochondria, they help to maintain cellular homeostasis. As post-mitotic neurons cannot dilute unwanted protein and organelle accumulation by cell division, the nervous system is particularly dependent on autophagic pathways.

Autophagic decline is considered a hallmark of ageing. The activity of this intracytoplasmic degradation pathway decreases with age in many tissues and autophagy induction ameliorates ageing in many organisms, including mice. Autophagy is a critical protective pathway in neurons and ageing is the primary risk factor for common neurodegenerative diseases.

Autophagy is an essential catabolic process induced to provide cellular energy sources in response to nutrient limitation through the activation of kinases, like AMP-activated protein kinase (AMPK) and ULK1. Although glucose starvation induces autophagy, the exact mechanism underlying this signaling has yet to be elucidated. Here, we reveal a role for ULK1 in non-canonical autophagy signaling using diverse cell lines.

BACKGROUND Abnormal posture can affect the alignment of the cervical spine, which can lead to various physical problems. There are many ways to solve the problem by limiting the area around the neck to restore abnormal neck condition. However, there is a need to look at these problems from an enlarged perspective through the relationship between the cervical spine and trunk.

Lowe syndrome is a rare, developmental disorder caused by mutations in the phosphatase, OCRL. A study in this issue of EMBO Reports shows that OCRL is required for microtubule nucleation and that mutations in this protein lead to an inability to activate mTORC1 signaling and consequent cell proliferation in the presence of nutrients. These defects are the result of impaired microtubule-dependent lysosomal trafficking to the cell periphery and are independent of OCRL phosphatase activity.

The factors regulating cellular identity are critical for understanding the transition from health to disease and responses to therapies. Recent literature suggests that autophagy compromise may cause opposite effects in different contexts by either activating or inhibiting YAP/TAZ co-transcriptional regulators of the Hippo pathway via unrelated mechanisms. Here, we confirm that autophagy perturbation in different cell types can cause opposite responses in growth-promoting oncogenic YAP/TAZ transcriptional signalling.

Posttranslational modifications of proteins, such as acetylation, are essential for the regulation of diverse physiological processes, including metabolism, development and aging. Autophagy is an evolutionarily conserved catabolic process that involves the highly regulated sequestration of intracytoplasmic contents in double-membrane vesicles called autophagosomes, which are subsequently degraded after fusing with lysosomes. The roles and mechanisms of acetylation in autophagy control have emerged only in the last few years.
