Apostatin-1
Based on 1 publication(s) in Google Scholar
Apostatin-1 (Apt-1) is a potent TRADD inhibitor. Apostatin-1 can bind with TRADD-N (KD=2.17 μM), disrupting its binding to both TRADD-C and TRAF2. Apostatin-1 modulates the ubiquitination of RIPK1 and beclin 1. Apostatin-1 blocks apoptosis and restores cellular homeostasis by activating autophagy in cells with accumulated mutant tau, α-synuclein, or huntingtin.

Apoptosis
Apoptosis, also called programmed cell death, is generally characterized by distinct morphological characteristics.

TUNEL staining for apoptotic DNA fragmentation
TUNEL staining detects DNA strand breaks by using terminal deoxynucleotidyl transferase to add labeled nucleotides to exposed 3′-OH DNA termini, generating either microscopic staining in fixed cells or tissue sections, or fluorescence/cytometric signal in cell suspensions. TUNEL positivity reflects DNA fragmentation but should not be interpreted alone as definitive apoptosis, because TUNEL can also label necrotic, autolytic, mechanically damaged, or DNA-repair-associated DNA breaks.

Annexin V plus membrane-impermeant dye apoptosis staining
Annexin V-based apoptosis assays rely on the detection of phosphatidylserine (PS) externalization from the inner leaflet of the plasma membrane to the outer leaflet, an early biochemical hallmark of apoptosis. Fluorescently labeled Annexin V binds PS in a calcium-dependent manner, enabling identification of early apoptotic cells by flow cytometry or fluorescence microscopy. When combined with a membrane-impermeant DNA-binding dye (e. g. , propidium iodide), this approach allows discrimination between viable (Annexin V−/dye−), early apoptotic (Annexin V+/dye−), and late apoptotic or necrotic (Annexin V+/dye+) cell populations by assessing membrane integrity and PS exposure.

Autophagy
Autophagy is a process in which eukaryotic cells use lysosomes to degrade their own cytoplasmic proteins and damaged organelles under the regulation of autophagy related gene (Atg). Microtubule-associated proteins light chain 3 (LC3) is recognized as autophagy marker, which transfers from cytoplasmic LC3 (LC3-I) to membrane type (LC3-II). LC3-II/I ratio could be detected by Western Blot and fluorescence microscopy.

Apoptosis Solutions
Apoptosis is a regulated, generally non-lytic cell-death pathway that removes unwanted, damaged, infected, or abnormal cells through coordinated morphological changes, caspase activation, DNA fragmentation, and membrane remodeling. The intrinsic apoptosis pathway is controlled mainly by mitochondrial outer membrane permeabilization, BCL-2 family proteins, cytochrome c release, apoptosome formation, caspase-9 activation, and downstream executioner caspase-3/7 activation. The extrinsic apoptosis pathway is initiated by death receptors such as Fas, TNFR, and TRAIL receptors, which recruit adaptor proteins and activate caspase-8 before engaging executioner caspases or mitochondrial amplification through BID cleavage. Apoptosis is linked to many phenotypes, including cancer cell killing, tissue homeostasis, immune regulation, neurodegeneration, infection response, and treatment-induced cytotoxicity; unresolved questions include how apoptosis interacts with necroptosis, pyroptosis, ferroptos

Lysosome and acidic-vesicle live-cell staining
Lysosome and acidic-vesicle live-cell staining detects acidic intracellular compartments by using membrane-permeant acidotropic probes that accumulate in low-pH vesicles, including lysosomes, late endosomes, autolysosomes, and acidic phagosomes. LysoTracker staining is commonly used as an intensity-based readout of acidic lysosomal compartment abundance or enlargement, while acridine orange produces green fluorescence in less concentrated compartments and red fluorescence after concentration-dependent accumulation in acidic vesicular organelles. Loss or reduction of acridine-orange red signal can be used as a readout of lysosomal membrane permeabilization or reduced acidic-vesicle integrity. This protocol is designed for live cultured cells and can be adapted for fluorescence microscopy, high-content imaging, plate-reader readout, or flow cytometry when the selected literature supports the readout. Because these dyes report acidotropic accumulation rather than lysosome identity alone,

Macroautophagy Solutions
Macroautophagy is a conserved lysosome-dependent degradation pathway in which cytoplasmic material is sequestered into double-membrane autophagosomes and delivered to lysosomes for degradation and recycling. The pathway supports cellular homeostasis during nutrient limitation, organelle stress, protein-aggregate accumulation, infection, differentiation, and tissue remodeling by coupling cargo sequestration, autophagosome maturation, lysosomal fusion, and degradation of cargo-derived macromolecules. The core molecular sequence includes initiation by nutrient- and stress-regulated autophagy machinery, autophagosome nucleation, LC3/ATG8-family conjugation to autophagosomal membranes, cargo selection through receptors such as SQSTM1/p62, autophagosome-lysosome fusion, and lysosomal degradation. LC3 was identified as a mammalian homolog of yeast Atg8 that localizes to autophagosomal membranes after processing, and p62/SQSTM1 was shown to connect ubiquitinated cargo with autophagic degradati
