Reversal of intramyocellular lipid accumulation by lipophagy and a p62-mediated pathway.

Cell death discovery

Lam T, Harmancey R, Vasquez H, Gilbert B, Patel N, Hariharan V, Lee A, Covey M, Taegtmeyer H.
PMID: 27625792
Cell Death Discov. 2016 Aug 22;2:16061. doi: 10.1038/cddiscovery.2016.61. eCollection 2016.

We have previously observed the reversal of lipid droplet deposition in skeletal muscle of morbidly obese patients following bariatric surgery. We now investigated whether activation of autophagy is the mechanism underlying this observation. For this purpose, we incubated rat...

Endocytosis and serpentine filopodia drive blebbishield-mediated resurrection of apoptotic cancer stem cells.

Cell death discovery

Jinesh GG, Kamat AM.
PMID: 27226900
Cell Death Discov. 2016;2. doi: 10.1038/cddiscovery.2015.69. Epub 2016 Jan 25.

The blebbishield emergency program helps to resurrect apoptotic cancer stem cells (CSCs) themselves. Understanding the mechanisms behind this program is essential to block resurrection of CSCs during cancer therapy. Here we demonstrate that endocytosis drives serpentine filopodia to construct...

Cdk2 phosphorylation of Bcl-xL after stress converts it to a pro-apoptotic protein mimicking Bax/Bak.

Cell death discovery

Megyesi J, Tarcsafalvi A, Seng N, Hodeify R, Price PM.
PMID: 27226901
Cell Death Discov. 2016;2. doi: 10.1038/cddiscovery.2015.66. Epub 2016 Jan 18.

Apoptosis is a regulated form of cell death that proceeds by defined biochemical pathways. Most apoptosis is controlled by interactions between pro-survival and pro-apoptotic Bcl-2 family proteins in which death is often the consequence of permeabilization of the mitochondrial...

iPS-derived MSCs from an expandable bank to deliver a prodrug-converting enzyme that limits growth and metastases of human breast cancers.

Cell death discovery

Ullah M, Kuroda Y, Bartosh TJ, Liu F, Zhao Q, Gregory C, Reger R, Xu J, Lee RH, Prockop DJ.
PMID: 28179988
Cell Death Discov. 2017 Feb 06;3:16064. doi: 10.1038/cddiscovery.2016.64. eCollection 2017.

One attractive strategy to treat cancers is to deliver an exogenous enzyme that will convert a non-toxic compound to a highly toxic derivative. The strategy was tested with viral vectors but was disappointing because the efficiency of transduction into...

Bystander effects elicited by single-cell photo-oxidative blue-light stimulation in retinal pigment epithelium cell networks.

Cell death discovery

Ishii M, Rohrer B.
PMID: 28179989
Cell Death Discov. 2017 Feb 06;3:16071. doi: 10.1038/cddiscovery.2016.71. eCollection 2017.

'Bystander effect' refers to the induction of biological effects in cells not directly targeted. The retinal pigment epithelium consists of hexagonal cells, forming a monolayer interconnected by gap junctions (GJs). Oxidative stress initiated in an individual cell by photostimulation...

A homolog of cyclophilin D is expressed in .

Cell death discovery

Bustos PL, Volta BJ, Perrone AE, Milduberger N, Bua J.
PMID: 28179991
Cell Death Discov. 2017 Feb 06;3:16092. doi: 10.1038/cddiscovery.2016.92. eCollection 2017.

Mitochondria have an important role in energy production, homeostasis and cell death. The opening of the mitochondrial permeability transition pore (mPTP) is considered one of the key events in apoptosis and necrosis, modulated by cyclophilin D (CyPD), a crucial...

Cell-free chromatin from dying cancer cells integrate into genomes of bystander healthy cells to induce DNA damage and inflammation.

Cell death discovery

Mittra I, Samant U, Sharma S, Raghuram GV, Saha T, Tidke P, Pancholi N, Gupta D, Prasannan P, Gaikwad A, Gardi N, Chaubal R, Upadhyay P, Pal K, Rane B, Shaikh A, Salunkhe S, Dutt S, Mishra PK, Khare NK, Nair NK, Dutt A.

Cell Death Discov. 2017 May 29;3:17015. doi: 10.1038/cddiscovery.2017.15. eCollection 2017.

Bystander cells of the tumor microenvironment show evidence of DNA damage and inflammation that can lead to their oncogenic transformation. Mediator(s) of cell-cell communication that brings about these pro-oncogenic pathologies has not been identified. We show here that cell-free...

A subset of patients with oral squamous cell carcinoma (OSCC), the most common subtype of head and neck squamous cell carcinoma (HNSCC), harbor dysplastic lesions (often visually identified as leukoplakia) prior to cancer diagnosis. Although evidence suggest that leukoplakia...

Caspase-mediated proteolysis of the sorting nexin 2 disrupts retromer assembly and potentiates Met/hepatocyte growth factor receptor signaling.

Cell death discovery

Duclos CM, Champagne A, Carrier JC, Saucier C, Lavoie CL, Denault JB.
PMID: 28179995
Cell Death Discov. 2017 Jan 23;3:16100. doi: 10.1038/cddiscovery.2016.100. eCollection 2017.

The unfolding of apoptosis involves the cleavage of hundreds of proteins by the caspase family of cysteinyl peptidases. Among those substrates are proteins involved in intracellular vesicle trafficking with a net outcome of shutting down the crucial processes governing...

Interplay of neuronal and non-neuronal genes regulates intestinal DAF-16-mediated immune response during .

Cell death discovery

Although precisely controlled innate immune response is governed by conserved cellular events in phylogenetically diverse hosts, the underlying molecular mechanisms by which this process is regulated against a multi-host pathogen remain unknown.

Mitochondrial pharmacology turns its sights on the Ca.

Colon cancer is a leading cause of cancer-related mortality for which targeted therapy is needed; however, trials using apoptosis-inducing ligand monotherapy to overcome resistance to apoptosis have not shown clinical responses. Since colon cancer cells selectively uptake and rapidly...
