To propagate their genetic material, flowering plants rely on the production of large amounts of pollen grains that are capable of germinating on a compatible stigma. Pollen germination and pollen tube growth are thought to be extremely energy-demanding processes. This raises the question of whether mitochondria from pollen grains are specifically tuned to support this developmental process.

Encapsulated BV6 and SM164, two bivalent second mitochondria-derived activator of caspase (Smac) mimetics, in etoposide (ETO)-lipopolymer nanoparticles (NPs) have been developed to deplete inhibitor of apoptosis proteins (IAP), impair DNA, and produce antagonistic effects on glioblastoma multiforme (GBM) in nude mice. The NPs, composed of cocoa butter (CB) and polyvinyl alcohol (PVA), were stabilized by glycerol monostearate and Pluronic F-127, and grafted with transferrin (Tf) and wheat germ agglutinin (WGA) to dock the blood-brain barrier (BBB) and degenerated dopaminergic neurons. The dual-targeting NPs increased the BBB permeability of BV6, SM164 and ETO via recognizing Tf receptor (TfR) and N-acetylglucosamine that are abundantly expressed on brain microvascular endothelial cells.

The study presents a detailed examination and follow-up of a Slovenian patient with an Leber Hereditary Optic Neuropathy (LHON)-like phenotype and bilateral optic neuropathy in whom genetic analysis identified a novel variant :m.15309T>C (Ile188Thr). We provide detailed analysis of the clinical examinations of a male patient with bilateral optic neuropathy from the acute stage to 8 years of follow-up.

Pathogenic variants of cause Charcot-Marie-Tooth disease (CMT), an inherited neuropathy characterized by axonal degeneration. GDAP1, an atypical glutathione S-transferase, localizes to the outer mitochondrial membrane (OMM), regulating this organelle's dynamics, transport, and membrane contact sites (MCSs). It has been proposed that GDAP1 functions as a cellular redox sensor.

Rett syndrome (RTT), which predominantly affects females, arises in most cases from mutations in the () gene. When MeCP2 is impaired, it disrupts the regulation of numerous genes, causing the production of dysfunctional proteins associated with various multi-systemic issues in RTT. In this review, we explore the current insights into molecular signaling related to monoamines, immune response, and mitochondrial function, and their implications for the pathophysiology of RTT.
