Association of changes in the type 2 diabetes and MASLD/related SLD status with risk of developing cardiovascular disease.

Background & Aims: This study assessed the association of remission of type 2 diabetes mellitus (DM) or metabolic dysfunction-associated steatotic liver disease (MASLD)/related SLD (r-SLD; MASLD with excessive alcohol intake) as defined by the fatty liver index with the risk of cardiovascular disease (CVD).

Methods: Health examination data at baseline and after 2 years (2-Years) were extracted from a nationwide claims database in Japan. Among participants aged 18-72 years with at least 3 years of follow-up, 9345 participants with DM-associated MASLD/r-SLD and 71 932 participants with non-DM MASLD/r-SLD at baseline were included in the study.

Role of hepcidin upregulation and proteolytic cleavage of ferroportin 1 in hepatitis C virus-induced iron accumulation.

Hepatitis C virus (HCV) is a pathogen characterized not only by its persistent infection leading to the development of cirrhosis and hepatocellular carcinoma (HCC), but also by metabolic disorders such as lipid and iron dysregulation. Elevated iron load is commonly observed in the livers of patients with chronic hepatitis C, and hepatic iron overload is a highly profibrogenic and carcinogenic factor that increases the risk of HCC. However, the underlying mechanisms of elevated iron accumulation in HCV-infected livers remain to be fully elucidated.

Nutritional Adequacy Assessment of the Japanese Diet Using the Number of Dishes Compared to Existing Dietary Diversity Indices: A Cross-Sectional Analysis from the 2012 National Health and Nutrition Survey, Japan.

The Japanese diet has attracted attention as a factor contributing to the Japanese population's longevity. A typical Japanese meal, traditionally called "ichiju-sansai," is composed of various dishes. This study assessed the nutritional adequacy of the Japanese diet using the number of dishes in all meals (NDAM) compared to existing dietary diversity indices (DDIs).

The Mc4r gene is responsible for the development of experimentally induced testicular teratomas.

Teratomas in mice, composed of different tissue types, are derived from primordial germ cells in the fetal gonads. Previously, we identified a locus responsible for experimental testicular teratoma (ETT) formation on chromosome 18, referred to as ett1. The strongest candidate sequence in the ett1 locus was found to be a missense mutation in the melanocortin 4 receptor (Mc4r), Mc4r.

The mechanosensitive ion channel PIEZO1 promotes satellite cell function in muscle regeneration.

Muscle satellite cells (MuSCs), myogenic stem cells in skeletal muscles, play an essential role in muscle regeneration. After skeletal muscle injury, quiescent MuSCs are activated to enter the cell cycle and proliferate, thereby initiating regeneration; however, the mechanisms that ensure successful MuSC division, including chromosome segregation, remain unclear. Here, we show that PIEZO1, a calcium ion (Ca)-permeable cation channel activated by membrane tension, mediates spontaneous Ca influx to control the regenerative function of MuSCs.
