UPR-inducible miRNAs contribute to stressful situations [PDF]

Trends in Biochemical Sciences, 2013
The endoplasmic reticulum (ER) senses both extracellular and intracellular stresses that can disrupt its ability to facilitate the maturation of proteins destined for secretory pathways. The accumulation of misfolded proteins within the ER triggers an adaptive signaling pathway coined the unfolded protein response (UPR).

Quantitative Proteomics and CRISPR/Cas9 Editing Reveal UPR‐Mediated Control of Immunoglobulin Homeostasis in Hybridomas

Advanced Science, EarlyView.
BCR sequencing and subclone analysis correlated immunoglobulin (Ig) chain loss in dysfunctional hybridomas with disrupted monoclonal antibody homeostasis. Proteomics‐guided CRISPR/Cas9 editing revealed that the unfolded protein response (UPR) regulates aberrant Ig synthesis.

Analysis of the management process of doctoral training in three Cuban universities

Revista MENDIVE, 2023
Doctoral training is the integrating nucleus not only of substantive university processes (teaching, research and extension) but also of the different forms of postgraduate and guarantor of university quality and, especially, of higher education ...

The mitochondrial UPR – protecting organelle protein homeostasis [PDF]

Journal of Cell Science, 2010
Mitochondria are required for numerous essential metabolic processes including the regulation of apoptosis; therefore, proper maintenance of the mitochondrial proteome is crucial. The protein-folding environment in mitochondria is challenged by organelle architecture, the presence of reactive oxygen species and the difficulties associated with assembly

Autophagy Activators Normalize Aberrant Tau Proteostasis and Rescue Synapses in Human Familial Alzheimer's Disease iPSC‐Derived Cortical Organoids

Advanced Science, EarlyView.
A new cerebrocortical organoid model using isogenic hiPSCs with familial Alzheimer's mutations recapitulates key AD features, including amyloid‐beta and phospho‐Tau aggregation, neuronal hyperexcitability, and synapse loss. Single‐cell RNA‐seq reveals aberrant pathways in excitatory and inhibitory neurons.

ER biogenesis without stress: how the ribosome receptor, p180, defines a developmental program beyond the UPR

Frontiers in Cell and Developmental Biology
The endoplasmic reticulum (ER) plays a central role in protein and lipid biosynthesis, quality control, and secretion. While its functional roles are well characterized, the mechanisms underlying ER biogenesis remain less defined.

Consensus clustering and functional interpretation of gene-expression data [PDF]

, 2004
Microarray analysis using clustering algorithms can suffer from lack of inter-method consistency in assigning related gene-expression profiles to clusters.

TXNIP Switches Tracks toward a Terminal UPR [PDF]

Cell Metabolism, 2012
During the progression of diabetes, crosstalk between ER stress and inflammation controls islet cell fate. In this issue, Lerner et al. (2012) and Oslowski et al. (2012) discover that thioredoxin-interacting protein (TXNIP) is a regulatory switch connecting the terminal unfolded protein response (UPR) and NLRP3 inflammasome to mediate β cell death.

Conversion of Transplanted Mature Hepatocytes into Afp+ Reprogrammed Cells for Liver Regeneration After Injury

Advanced Science, EarlyView.
Donor‐derived tdTomato+ mature hepatocytes were FACS‐isolated and transplanted into Fah−/− host mice. During regeneration, these cells convert into proliferative, unipotent Afp+ rHeps. Their plasticity is governed by a PPARγ/AFP‐dependent metabolic switch, segregating into pro‐proliferative Afplow and pro‐survival Afphigh subpopulations.
