Tau and Caspase 3 as Targets for Neuroprotection [PDF]

International Journal of Alzheimer's Disease, 2012
The peptide drug candidate NAP (davunetide) has demonstrated protective effects in variousin vivoandin vitromodels of neurodegeneration. NAP was shown to reduce tau hyperphosphorylation as well as to prevent caspase-3 activation and cytochrome-3 release from mitochondria, both characteristic of apoptotic cell death. Recent studies suggest that caspases

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

Expression of caspase-3, caspase-9, GDF-9 and IGF-1 genes in ovine oocytes cultured with optimum and elevated doses of Amphiregulin, Neuregulin-1 and Tumour necrosis factor-α in-vitro

Indian Journal of Animal Sciences, 2022
The present study was conducted to evaluate the expression of caspase-3, caspase-9, growth differentiation factor-9 (GDF-9) and insulin growth factor-1 (IGF-1) genes in oocytes cultured in vitro with optimum and elevated doses of amphiregulin (50 ng and

Caspase-9, caspase-3 and caspase-7 have distinct roles during intrinsic apoptosis [PDF]

BMC Cell Biology, 2013
AbstractBackgroundApoptosis is a form of programmed cell death that is regulated by the Bcl-2 family and caspase family of proteins. The caspase cascade responsible for executing cell death following cytochromecrelease is well described; however the distinct roles of caspases-9, -3 and -7 during this process are not completely defined.ResultsHere we ...

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

The expression of caspase-3, caspase-7, caspase-9 and cytokeratin AE1/AE3 in goats with enzootic nasal adenocarcinoma: an immunohistochemical study

Veterinární Medicína, 2013
The aim of this study was to examine the expression of caspase-3, caspase-7, caspase-9 and cytokeratin AE-1/AE-3 using the avidin-biotin complex (ABC) immunoperoxidase technique in 20 goats with enzootic nasal adenocarcinoma (ENA).

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

Molecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Chicken GSDME, a major pore-forming molecule responsible for RNA virus-induced pyroptosis in chicken

Journal of Virology
Pyroptosis is an inflammatory type of programmed cell death that mainly depends on the formation of plasma membrane pores by Gasdermin D (GSDMD) in mammals. However, the genetic deficiency of GSDMD in chicken renders avian pyroptosis elusive.
