Genotoxic anti-cancer therapies such as chemotherapy and radiotherapy can contribute to an increase in second malignancies in cancer survivors due to their oncogenic effects on non-cancerous cells. Inhibition of histone deacetylase (HDAC) proteins or the proteasome differ from chemotherapy in that they eliminate cancer cells by regulating gene expression or cellular protein equilibrium, respectively. As members of these drug classes have been approved for clinical use in recent times, we investigated whether these two drug classes exhibit similar mutagenic capabilities as chemotherapy. Read More

Outcomes of melanoma patient treatment remain unsatisfactory despite accessibility of oncoprotein-targeting drugs and immunotherapy. Here, we reported that 17-aminogeldanamycin more potently activated caspase-3/7 in BRAF melanoma cells than geldanamycin, another inhibitor of heat shock protein 90 (HSP90). 17-aminogeldanamycin alleviated self-triggered compensatory increase in HSP70 mRNA level and induced endoplasmic reticulum (ER) stress, which was followed by selective diminution of cytoprotective IRE1α-XBP1s pathway activity of unfolded protein response (UPR), inhibition of ERK1/2 activity and induction of apoptosis.

Calreticulin (CRT) is a pleiotropic and highly conserved molecule that is mainly localized in the endoplasmic reticulum. Recently, CRT has gained special interest for its functions outside the endoplasmic reticulum where it has immunomodulatory properties. CRT translocation to the cell membrane serves as an "eat me" signal and promotes efferocytosis of apoptotic cells and cancer cell removal with completely opposite outcomes. Read More

Lipoapoptosis of cardiomyocytes may underlie diabetic cardiomyopathy. Numerous forms of cardiomyopathies share a common end-pathway in which apoptotic loss of cardiomyocytes is mediated by p38α mitogen activated protein kinase (MAPK). Although we have previously shown that palmitic acid (PA), a saturated fatty acid (SFA) elevated in plasma of type 2 diabetes mellitus and morbid obesity, induces apoptosis in cardiomyocytes via p38α MAPK-dependent signaling, the downstream cascade events that cause cell death remain unknown.

Although new cancer therapeutics are discovered at a rapid pace, lack of effective means of delivery and cancer chemoresistance thwart many of the promising therapeutics. We demonstrate a method that confronts both of these issues with the light-activated delivery of a Bcl-2 functional converting peptide, NuBCP-9, using hollow gold nanoshells. This approach has shown not only to increase the efficacy of the peptide 30-fold in vitro but also has shown to reduce paclitaxel resistant H460 lung xenograft tumor growth by 56. Read More

Idiopathic pulmonary fibrosis (IPF) is a deadly and progressive fibrotic lung disease, but the precise etiology remains elusive. IPF is characterized by the presence of apoptosis-resistant (myo)fibroblasts that relentlessly produce a collagen-rich extracellular matrix (ECM). Recent studies showed that an anti-cancer chemotherapy drug cisplatin is implicated in the development of pulmonary fibrosis, suggesting that the treatment of cancer patients with cisplatin may alter fibroblast viability.

Tumor necrosis factor-α (TNF-α), a pro-inflammatory cytokine considered to be implicated in the pathogenesis of major depressive disorder, is a critical regulator of neuronal cell fate. In the present study we found that TNF-α-induced apoptosis of HT22 hippocampal cells, a neuroblast-like cell line, was markedly attenuated by the antidepressants mianserin, mirtazapine and amitriptyline. The anti-apoptotic effect of the antidepressants was blocked by either pharmacological inhibition or gene silencing of the lysophosphatidic acid receptor LPA. Read More

Currently the study of Regulated Cell Death (RCD) processes is limited to the use of lysed cell populations for Western blot analysis of each separate RCD process. We have previously shown that intracellular antigen flow cytometric analysis of RIP3, Caspase-3 and cell viability dye allowed the determination of levels of apoptosis (Caspase-3/RIP3), necroptosis (RIP3/Caspase-3) and RIP1-dependent apoptosis (Caspase-3/RIP3) in a single Jurkat cell population. The addition of more intracellular markers allows the determination of the incidence of parthanatos (PARP), DNA Damage Response (DDR, H2AX), H2AX hyper-activation of PARP (H2AX/PARP) autophagy (LC3B) and ER stress (PERK), thus allowing the identification of 124 sub-populations both within live and dead cell populations.

Paclitaxel is one of the most commonly used drugs for the treatment of nonsmall cell lung cancer (NSCLC). However acquired resistance to paclitaxel, epithelial to mesenchymal transition and cancer stem cell formation are the major obstacles for successful chemotherapy with this drug. Some of the major reasons behind chemoresistance development include increased ability of the cancer cells to survive under stress conditions by autophagy, increased expression of drug efflux pumps, tubulin mutations etc. Read More

During the development of cardiac hypertrophy, glucose deprivation (GD) associated with coronary microvascular rarefaction is caused, leading to cardiomyocyte death. Phosphorylation (inactivation) of eukaryotic elongation factor 2 (eEF2) by eEF2 kinase (eEF2K) inhibits protein translation, a highly energy consuming process, which plays protective roles against nutrient deprivation-induced cell death. We previously showed that eEF2 phosphorylation was increased in isolated heart from several cardiac hypertrophy models. Read More

It has been well established that radiation-induced gastrointestinal injury is manifested through loss of intestinal crypt stem cells and disruption of the mucosal layers, resulting in diarrhoea, weight loss, electrolyte imbalance, infection and mortality. Podophyllotoxin and rutin in combination (G-003M) has been reported to regulate endogenous cellular antioxidant defense systems and inflammatory response. However, the mechanism by which G-003M ameliorates radiation-induced intestinal stem cell (ISC) injury remains unclear. Read More

Cell death through apoptosis, necrosis, necroptosis and pyroptosis, as well as the clearance of dead cells are crucial biological processes in the human body. Likewise, disassembly of dying cells during apoptosis to generate cell fragments known as apoptotic bodies may also play important roles in regulating cell clearance and intercellular communication. Recent advances in the field have led to the development of new experimental systems to identify cells at different stages of cell death, measure the levels of apoptotic cell disassembly, and monitor the cell clearance process using a range of in vitro, ex vivo and in vivo models.

One major characteristic of programmed cell death (apoptosis) results in the increased expression of phosphatidylserine (PS) on the outer membrane of dying cells. Consequently, PS represents an excellent target for non-invasive imaging of apoptosis by single-photon emission computed tomography (SPECT) and positron emission tomography (PET). Annexin V is a 36 kDa protein which binds with high affinity to PS in the presence of Ca ions. Read More

Smac mimetics that deplete cellular inhibitor of apoptosis (cIAP) proteins have been shown to activate Nuclear Factor-kappa B (NF-κB). Here, we report that Smac mimetic-mediated activation of NF-κB contributes to the rescue of cancer cells from tunicamycin (TM)-triggered apoptosis. The prototypic Smac mimetic BV6 activates non-canonical and canonical NF-κB pathways, while TM has little effect on NF-κB signaling. Read More

In Drosophila melanogaster a significant number of heterogenous larval neurons in the central nervous system undergo metamorphosis-associated programmed cell death, termed metamorphoptosis. Interestingly distinct groups of doomed larval neurons are eliminated at different metamorphic phases. Although ecdysone hormonal signaling via nuclear ecdysone receptors (EcRs) is known to orchestrate the neuronal metamorphoptosis, little is known about how this signaling controls such diverse neuronal responses.

Reports have showed that Sigma-1 receptor (Sig-1R) activation can protect neurons against cerebral ischemia/reperfusion (I/R) injury in mice and alleviate endoplasmic reticulum (ER) stress in cultured cells, but little known is about the protective role of Sig-1R on ER stress induced by cerebral I/R. The purpose of this study was to determine whether Sig-1R exerts a protective effect against ER stress-mediated apoptosis in cerebral I/R using a 15-min bilateral common carotid artery occlusion (BCCAO) mouse model. At 72 h after reperfusion in BCCAO mice, we found that Sig-1R knockout (Sig-1R KO) significantly increased terminal dUTP nick-end labeling (TUNEL)-positive cells and nuclear structural damage in cortical neurons.
