Autophagy markers expression pattern in developing liver of the yotari (dab1) mice and humans.

Autophagy plays an important role in the physiology and pathology of the liver. Several negative autophagy regulators have been discovered, including epidermal growth factor receptor (EGFR), mediated by activation of the PI3K/Akt/mTOR signaling pathway. Disabled-1 (Dab1) is one of the mediating adaptor factors of PI3K/Akt/mTOR signaling pathways.

Immunoexpression Pattern of Autophagy Markers in Developing and Postnatal Kidneys of ) Mice.

The purpose of this study was to compare the immunofluorescence patterns of autophagic markers: Light chain 3 beta (LC3B), Glucose regulating protein 78 (GRP78), Heat shock cognate 71 (HSC70) and Lysosomal-associated membrane protein 2A (LAMP2A) in the developing and postnatal kidneys of () mice to those of wild-type samples. Embryos were obtained on gestation days 13.5 and 15.

Hsp90 inhibitor gedunin causes apoptosis in A549 lung cancer cells by disrupting Hsp90:Beclin-1:Bcl-2 interaction and downregulating autophagy.

Aims: Hsp90 is regarded as an important therapeutic target in cancer treatment. Client proteins of Hsp90 like Beclin-1, PI3K, and AKT, are associated with tumor development, poor prognosis, and resistance to cancer therapies. This study aims to analyze the role of Gedunin, an Hsp-90 inhibitor, in mediation of crosstalk between apoptosis and autophagy by targeting Beclin-1:Bcl-2 interaction, and ER stress.

Advanced glycation end products (AGEs), protein aggregation and their cross talk: new insight in tumorigenesis.

Protein glycation and protein aggregation are two distinct phenomena being observed in cancer cells as factors promoting cancer cell viability. Protein aggregation is an abnormal interaction between proteins caused as a result of structural changes in them after any mutation or environmental assault. Protein aggregation is usually associated with neurodegenerative diseases like Alzheimer's and Parkinson's, but of late, research findings have shown its association with the development of different cancers like lung, breast and ovarian cancer.

Blocking mutation independent p53 aggregation by emodin modulates autophagic cell death pathway in lung cancer.

Loss of p53 function via mutation is a very common cause of human cancers. Recent studies have provided evidence on presence of self aggregated p53 in cancer cells leading to its altered functions towards cause of cancer. The general notion has been that mutated p53 exposes adhesive sites that promote self aggregation, however a complete mechanistic understanding to this has been lacking.

ER chaperone GRP78 regulates autophagy by modulation of p53 localization.

GRP78 (glucose regulated protein 78) is a major Endoplasmic Reticulum (ER) chaperone that plays a pivotal role in normal ER functioning. Its increased expression also works as an indicator of ER stress. Its anti-apoptotic and pro-autophagic activity makes it an intriguing target to study the relationship between GRP78 and p53, which is also a major regulator of apoptosis and autophagy.

Cissus quadrangularis Linn. Stem Ethanolic Extract Liberates Reactive Oxygen Species and Induces Mitochondria Mediated Apoptosis in KB Cells.

Background: Cissus quadrangularis Linn. (CQ) commonly known as Hadjod (Family: Vitaceae) is usually distributed in India and Sri Lanka and contains several bioactive compounds responsible for various metabolic and physiologic effects.

Objective: In this study, the biological effects of CQ ethanolic extract were evaluated by in vitro and supported by in silico analysis on KB oral epidermoid cancer cell line.

The Chromone Alkaloid, Rohitukine, Affords Anti-Cancer Activity via Modulating Apoptosis Pathways in A549 Cell Line and Yeast Mitogen Activated Protein Kinase (MAPK) Pathway.

The field of cancer research and treatment has made significant progress, yet we are far from having completely safe, efficient and specific therapies that target cancer cells and spare the healthy tissues. Natural compounds may reduce the problems related to cancer treatment. Currently, many plant products are being used to treat cancer.

Neurodegenerative Diseases: Multifactorial Conformational Diseases and Their Therapeutic Interventions.

Neurodegenerative diseases are multifactorial debilitating disorders of the nervous system that affect approximately 30 millionindividuals worldwide. Neurodegenerative diseases such as Alzheimer's, Parkinson's, Huntington's, and amyotrophic lateral sclerosis diseases are the consequence of misfolding and dysfunctional trafficking of proteins. Beside that, mitochondrial dysfunction, oxidative stress, and/or environmental factors strongly associated with age have also been implicated in causing neurodegeneration.
