Additionally, the sequencing analysis showed that the stachyose changed the gut microbiota composition with a higher level of Akkermansia, as well as selectively increasing some probiotics, including Lactobacillus. Conclusions Our results suggested that stachyose increased beneficial microbiota and bacterial diversity to alleviate acute colitis in mice, which might be a new promising option to UC patients.Background/Aims Colorectal cancer (CRC) is the third most common malignant tumour worldwide and the second leading cause of cancer-related deaths. Commonly, 5'-aminolevulinic acid synthase1 (ALAS1) is the rate-limiting enzyme for haem biosynthesis. Recent studies have shown that ALAS1 is involved in a number of cellular functions and has significant effects on non-small cell lung cancer (NSCLC). However, current concepts of disease pathogenesis fail to fully explain the role of ALAS1 expression and biological functions in CRC. Materials and Methods A total of 67 paired tumour tissues and adjacent colorectal tissues were used to detect ALAS1 levels and further analyse the correlation between ALAS1 expression levels and clinical features. Using HCT116 cell lines, we studied the impact of ALAS1 on biological function by knocking down or inhibiting ALAS1. Results We found an increase in the levels of ALAS1 in cancer tissues compared to adjacent colorectal tissues. The increase in ALAS1 expression was closely related to the invasion depth, N staging and tumour size of CRC patients. The proliferation and metastasis of CRC cells could be inhibited by suppressing ALAS1. Conclusions The abnormal expression of ALAS1 is closely related to the proliferation and metastasis of CRC cells, suggesting that ALAS1 may be a novel therapeutic target for the treatment of CRC.The mammalian epididymis not only plays a fundamental role in the maturation of spermatozoa, but also provides protection against various stressors. Retatrutide The foremost among these is the threat posed by oxidative stress, which arises from an imbalance in reactive oxygen species and can elicit damage to cellular lipids, proteins, and nucleic acids. In mice, the risk of oxidative damage to spermatozoa is mitigated through the expression and secretion of glutathione peroxidase 5 (GPX5) as a major luminal scavenger in the proximal caput epididymidal segment. Accordingly, the loss of GPX5-mediated protection leads to impaired DNA integrity in the spermatozoa of aged Gpx5-/- mice. To explore the underlying mechanism, we have conducted transcriptomic analysis of caput epididymidal epithelial cells from aged (13 months old) Gpx5-/- mice. This analysis revealed the dysregulation of several thousand epididymal mRNA transcripts, including the downregulation of a subgroup of piRNA pathway genes, in aged Gpx5-/- mice. In agreement with these findings, we also observed the loss of piRNAs, which potentially bind to the P-element-induced wimpy testis (PIWI)-like proteins PIWIL1 and PIWIL2. The absence of these piRNAs was correlated with the elevated mRNA levels of their putative gene targets in the caput epididymidis of Gpx5-/- mice. Importantly, the oxidative stress response genes tend to have more targeting piRNAs, and many of them were among the top increased genes upon the loss of GPX5. Taken together, our findings suggest the existence of a previously uncharacterized somatic piRNA pathway in the mammalian epididymis and its possible involvement in the aging and oxidative stress-mediated responses.Background Linear cutaneous lupus erythematosus is a rare subtype of lupus erythematosus (LE) that develops linear lesions following the lines of Blaschko. Linear cutaneous lupus erythematosus may present as various subtypes of LE, including linear discoid lupus erythematosus. There are few reports about pigmentedlinear discoid lupus erythematosus in the literature. Aims We aimed to summarize the clinical and pathological features of patients with pigmented linear discoid lupus erythem
