Bacterial strains belonging to the same species vary considerably in gene content. Thus, the genetic repertoire of a given species (its "pan-genome") is much larger than the gene content of individual strains. These variations in DNA material, together with differences in genomic structure and nucleotide polymorphisms among strains, confer upon prokaryotic species a phenomenal adaptability. Although the approach of sequencing multiple strains from a single species remains the main and often easiest way to study the pan-genome, feasible alternatives include those related to DNA hybridization. In other cases, the use of metagenomic sequences is already applicable by data mining from the growing metagenomic databases. Eventually, the single-cell genome approach might be the ideal solution. The pan-genome concept has important consequences for the way we understand bacterial evolution, adaptation, and population structure, as well as for more applied issues such as vaccine design or the identification of virulence genes.

Background: Stomach adenocarcinoma (STAD) is an aggressive malignancy characterized by high tumor plasticity and heterogeneity. This study investigates the role of Autophagy and Beclin 1 Regulator 1 (AMBRA1) in regulating tumor plasticity in STAD progression.
Methods: Combined with clinical data, the pan-cancer analysis of AMBRA1 was performed to analyze the role of AMBRA1 in STAD.

This study examined the effects of on the growth performance, innate immunity, and gut microbiota of under different water temperature conditions. Feeding regimens included a 20% fishmeal diet (control), a low-fish meal (LFM) diet with 10% fishmeal and an LFM diet supplemented with 0.03% .
Background: Nephrotic syndrome has a significant impact on global health, often leading to cardiovascular disease and high mortality due to limited effective treatments. This study investigates the efficacy of Shensu IV in a puromycin aminonucleoside (PAN)-induced rat model of nephropathy.
Methods: Rat models and podocyte PAN nephropathy models were established with PAN and treated with Shensu IV.
G protein-coupled estrogen receptor 1 (GPER1) plays a crucial role in the progression of breast cancer and has emerged as a promising therapeutic target. However, while missense mutations in GPER1 have been detected in breast invasive carcinoma (BIC) samples, the resulting molecular, cellular and pharmacological changes remain unclear. The present study categorized BIC samples from The Cancer Genome Atlas database based on mutation information available in the cBioPortal database.
The mushroom is consumed worldwide and has high industrial value because of its rich content of bioactive compounds such as ergothioneine and eritadenine. Currently, mainstream artificial cultivation methods for this mushroom typically use synthetic logs. However, browning of the stem's interior (stem browning) has been observed during the cultivation in some strains.
