BGPT: Meta-analysis: mitochondria transfer infertility heterologous vs autologous live birth

Explore by Goal

Long Analysis Plan Copied

The supplied evidence records do not address mitochondrial transfer therapy for infertility. They cover skeletal muscle ankyrin-B/fission , tumor mitochondrial biochemistry, fish ROS, MAMs, ischemia-reperfusion, calcium buffering, ultrastructure, and nitric oxide inhibition — none contain live-birth data for heterologous vs autologous mitochondria replacement in ART.

What is missing to run this meta-analysis: patient-level or aggregate live-birth rates, embryo transfer outcomes, donor-source definition (heterologous donor oocyte/blastocyst vs autologous), comparator arms, and study identifiers for trials of mitochondrial replacement or cytoplasmic transfer in infertility. No such evidence units were supplied, so no effect estimate or graph can be honestly produced from the provided data.

1. The study shows that skeletal muscle ankyrin-B (AnkB) promotes mitochondria fission by coordinating Drp1 and MFF at the outer mitochondrial membrane and supports SR–mitochondria coupling and Ca2+ homeostasis, with skeletal muscle–specific AnkB loss causing hyperfused mitochondria, impaired fatty acid oxidation, heightened energetic stress during endurance exercise, and reduced endurance capacity.

3. This study investigates the production of mitochondrial reactive oxygen species (ROS) in fish muscle mitochondria and its potential role in oxidative stress induced by acute heat exposure, revealing that fish mitochondria may produce ROS at higher rates than rat mitochondria under certain conditions.

11. This study presents a novel method for isolating mitochondria from the myxomycete Physarum polycephalum and provides evidence for DNA-dependent RNA synthesis and protein synthesis in these isolated mitochondria, highlighting the potential role of mitochondrial DNA in coding for proteins. [1973]

12. This study investigates the sensitivity of mitochondrial protein synthesis in mouse brain and liver to inhibition by chloramphenicol and cycloheximide, revealing a potassium-dependent mechanism in brain mitochondria that differs from liver mitochondria. [1970]
