Diseases associated with the accumulation of lipid droplets are increasing in western countries. Lipid droplet biogenesis, structure and degradation are regulated by proteins of the perilipin family. Perilipin 5 has been shown to regulate basal lipolysis in oxidative tissues. We examine perilipin 5 in normal human tissues and in diseases using protein biochemical and microscopic techniques. Perilipin 5 was constitutively located at small lipid droplets in skeletal myocytes, cardiomyocytes and brown adipocytes...

A wide range of neuroimmunological diseases, referred to as autoimmune neuropathies, affect the peripheral nervous systems (PNS). The PNS is structurally diverse with complex anatomical compartments enriched in many different myelin and neuronal glycolipids, notably gangliosides. Autoimmune neuropathies are a proportion of autoimmune neuropathies mediated by autoimmune attack due to antibodies reactive with these compartmentally localized gangliosides. Antiganglioside antibodies are principally associated with the acute paralytic disease, Guillain-Barré syndrome, and are also found in several chronic autoimmune neuropathy syndromes...

Cell-penetrating peptides (CPPs) can deliver payloads into cells by forming complexes with bioactive molecules via covalent or non-covalent bonds. Various CPPs have been applied in CPP-modified liposomes, and their effectiveness is highly regarded in liposomal drug delivery systems (DDSs). Previously, we have reported on the polyhistidine peptide (H16 peptide: HHHHHHHHHHHHHHHH-NH2 ) as a new CPP. The H16 peptide has a higher cell-penetrating capacity than well-known CPPs and delivers small molecules such as fluorescent dyes, bioactive peptides, and proteins into mammalian cells...

Plants use receptor-like kinases to monitor environmental changes and transduce signals into plant cells. The Medicago truncatula DOES NOT MAKE INFECTIONS 2 (DMI2) protein functions as a co-receptor of rhizobial signals to initiate nodule development and rhizobial infection during nitrogen-fixing symbiosis, but the mechanisms regulating DMI2 protein level and folding are still unknown. Here we report that DMI2 protein abundance changes during nitrogen-fixing symbiosis. DMI2 accumulates in the nodules and is induced by rhizobia treatment through a posttranscriptional process...

The persistence of hepatitis B surface antigen (HBsAg) is a risk factor for the development of steatosis-associated tumors in chronic hepatitis B virus (HBV) infection, yet little is known about the metabolic link with this factor. We correlated HBV-related pathogenesis in genetically engineered mice and human carriers with metabolic proteomics and lipogenic gene expression profiles. The immunohistochemistry showed that the promyelocytic leukemia protein (PML, a tumor suppressor involved in genome maintenance and fatty acid oxidation), being inversely influenced by the dynamic HBsAg levels from acute phase to seroclearance, appeared as a lipo-metabolic switch linking HBsAg-induced steatosis (lipogenesis) to HBsAg-lost fat-burning hepatocarcinogenesis (lipolysis)...

Li-CO2 batteries could skillfully combine the reduction of "greenhouse effect" with energy storage systems. However, Li-CO2 batteries still suffer from unsatisfactory electrochemical performances and their rechargeability is challenged. Here, it is reported that a composite of Ni nanoparticles highly dispersed on N-doped graphene (Ni-NG) with 3D porous structure, exhibits a superior discharge capacity of 17 625 mA h g-1 , as the air cathode for Li-CO2 batteries. The batteries with these highly efficient cathodes could sustain 100 cycles at a cutoff capacity of 1000 mA h g-1 with low overpotentials at the current density of 100 mA g-1 ...

Effective transfection of genetic molecules such as DNA usually relies on vectors that can reversibly uptake and release these molecules, and protect them from digestion by nuclease. Non-viral vectors meeting these requirements are rare due to the lack of specific interactions with DNA. Here, we design a series of four isoreticular metal-organic frameworks (Ni-IRMOF-74-II to -V) with progressively tuned pore size from 2.2 to 4.2 nm to precisely include single-stranded DNA (ssDNA, 11-53 nt), and to achieve reversible interaction between MOFs and ssDNA...

Increasing the dietary fat content of ruminant diets decreases methane (CH4 ) production. This effect is caused by the toxic properties of fatty acids on rumen microbial populations, coating of feed particles diminishing the accessibility for microbes, and a reduction in dry matter intake (DMI). The latter effect is caused by postabsorptive long-chain fatty acids eliciting anorexic signaling; however, whether circulating long-chain fatty acids affect rumen CH4 production alike is unknown. To approach this question, 5 rumen-cannulated Holstein cows in late lactation received 2 jugular catheters and were kept in respiration chambers to measure CH4 production and DMI for 48 h...

A noninvasive and selective therapy, photodynamic therapy (PDT) is widely researched in clinical fields; however, the lower efficiency of PDT can induce unexpected side effects. Mitochondria are extensively researched as target sites to maximize PDT effects because they play crucial roles in metabolism and can be used as cancer markers due to their high transmembrane potential. Here, a mitochondria targeting photodynamic therapeutic agent (MitDt) is developed. This photosensitizer is synthesized from heptamethine cyanine dyes, which are conjugated or modified as follows...
