Autophagy is an important intracellular process to maintain homeostasis and studies have shown the key role of autophagy in modulating the functions of reproductive system. Alongside with it, the activation of autophagy has also been found to regulate a number of important processes involved in in vitro fertilization including degeneration of granulosa cells and oocyte defects in obese and aging women; apoptosis of oocytes during vitrification-warming; quality and viability of embryo; developmental competence and pre-implantation development of in vitro produced blastocysts; placental vascularization and fetal growth. The different mechanisms that may contribute in autophagy-mediated increase in developmental competence and pre-implantation development include decrease in endoplasmic reticulum (ER) stress, activation of poly(ADP-ribosyl)ation (PARP) and reduction in free radical production. The present review discusses the role of autophagy activation in increasing the efficiency of in vitro fertilization by modulating different aspects related to fertilization.

Autophagy is an evolutionary conserved process that is responsible for maintaining cellular homeostasis through lysosome-dependent degradation of damaged proteins, lipid and organelles. When autophagy...
The nuclear orphan receptor (Nurr1) has recently received a perceivable solicitude as a target for the therapeutic intervention against PD. Meanwhile, the dysregulation of autophagy, along with other ...
Prions use cellular machineries for autocatalytic propagation by conformational conversion of the cellular prion protein into the pathological isoform PrP. Autophagy is a basic cellular degradation an...
Curcumin has been reported to possess cardioprotective effects. However, the potential molecular mechanism of curcumin is still not clear. The aim of the present study was to investigate the role of c...
Estrogen receptor (ER) antagonist, tamoxifen has been universally used for the treatment of the ER-positive breast cancer; however, inevitable emergence of resistance to tamoxifen obstructs the succes...
Autophagy is recognized as a central mechanism for the regulation of aging. . Osteoporosis (OA) and Alzheimer's disease (AD) are two forms of pathological aging, sometimes entangled, inclu...
The goal of this pilot and feasibility study is to investigate the effects of a short course of metformin therapy on a surrogate marker of cellular senescence and autophagy among adult pat...
The goal of this study is to adapt and test the feasibility and potential efficacy of a theory-driven pre-implementation intervention to address individual-level barriers to EBP implementa...
One recent study demonstrated impaired autophagy in patients receiving hemodialysis (HD). To clarify whether this alteration is related to the inflammatory state in HD patients, we focused...
The exact mechanism of impairment of autophagy in vitiligo has not yet been determined.
Loss of detectable antigen from the surface of a cell after incubation with antibodies. This is one method in which some tumors escape detection by the immune system. Antigenic modulation of target antigens also reduces the therapeutic effectiveness of treatment by monoclonal antibodies.
A methylxanthine naturally occurring in some beverages and also used as a pharmacological agent. Caffeine's most notable pharmacological effect is as a central nervous system stimulant, increasing alertness and producing agitation. It also relaxes SMOOTH MUSCLE, stimulates CARDIAC MUSCLE, stimulates DIURESIS, and appears to be useful in the treatment of some types of headache. Several cellular actions of caffeine have been observed, but it is not entirely clear how each contributes to its pharmacological profile. Among the most important are inhibition of cyclic nucleotide PHOSPHODIESTERASES, antagonism of ADENOSINE RECEPTORS, and modulation of intracellular calcium handling.
A serine/threonine-protein kinase that functions in AUTOPHAGY in response to starvation. It acts on the PHOSPHATIDYLINOSITOL 3-KINASE complex PIK3C3 to regulate AUTOPHAGOSOME formation. It also functions as both a downstream effector and negative regulator of mammalian target of rapamycin complex 1 (mTORC1) and is activated by AMPK, which it also negatively regulates.
Proteins and enzymes that function, often as components of MULTIPROTEIN COMPLEXES, to assemble AUTOPHAGOSOMES and carry out AUTOPHAGY.
An autophagy related protein that is similar to UBIQUITIN-ACTIVATING ENZYME E1. It functions in CYTOPLASM to VACUOLE transport (Cvt) and AUTOPHAGY by activating ATG12 PROTEIN for its conjugation with ATG5 PROTEIN, as well as the conjugation of ATG8 FAMILY PROTEINS with phosphatidylethanolamine for ATG8 association to Cvt vesicles and AUTOPHAGOSOME membranes. It is also required for the nitrogen starvation response in yeast, MITOPHAGY; and autophagic cell death induced by CASPASE 8 inhibition.
Obesity is the condition in which excess fat has accumulated in the body (mostly in subcutaneous tissues). clinical obesity is considered to be present when a person has a BMI of over 30 (Oxford Dictionary of Medicine). It is becoming increasing common i...
