Untangling determinants of gut microbiota and tumor immunologic status through a multi-omics approach in colorectal cancer.

The changes in gut microbiota have been implicated in colorectal cancer (CRC). The interplays between the host and gut microbiota remain largely unclear, and few studies have investigated these interplays using integrative multi-omics data. In this study, large-scale multi-comic datasets, including microbiome, metabolome, bulk transcriptomics and single cell RNA sequencing of CRC patients, were analyzed individually and integrated through advanced bioinformatics methods.

Short-term waterlogging-induced autophagy in root cells of wheat can inhibit programmed cell death.

Autophagy is a pathway for the degradation of cytoplasmic components in eukaryotes. In wheat, the mechanism by which autophagy regulates programmed cell death (PCD) is unknown. Here, we demonstrated that short-term waterlogging-induced autophagy inhibited PCD in root cells of wheat.

Entecavir-induced interferon-λ1 suppresses type 2 innate lymphoid cells in patients with hepatitis B virus-related liver cirrhosis.

The immunomodulatory effects of entecavir (ETV) in anti-hepatitis B virus (HBV) therapy have long been recognized. This study aimed to determine the effects of ETV on non-natural killer innate lymphoid cells (non-NK ILCs) in HBV-related liver disease progression. We enrolled treatment-naïve chronic hepatitis B (CHB) and HBV-related liver cirrhosis (LC) patients treated with ETV for 24 months.

Mutual regulation of ROS accumulation and cell autophagy in wheat roots under hypoxia stress.

Here, we explored the mutual regulation of radical oxygen species (ROS) and autophagy in wheat (Triticum aestivum L.) roots under hypoxia stress. We also analyzed differences between the responses of the stele and the cortex in the two wheat cultivars Huamai 8 (waterlogging-tolerant) and Huamai 9 (waterlogging-sensitive) to hypoxia stress.

The small heterodimer partner inhibits activation of hepatic stellate cells via autophagy.

Background: Hepatic fibrosis is a health concern worldwide, and it is of great importance to develop effective therapeutic targets. The small heterodimer partner (SHP) is a regulator of lipid and bile acid metabolism in the liver.

Objectives: The objective of this study was to investigate the contribution of SHP to hepatic fibrosis and the underlying mechanism.

Longitudinal monitoring of liver fibrosis status by transient elastography in chronic hepatitis B patients during long-term entecavir treatment.

The correlation between improvement in longitudinal liver stiffness and fibrosis regression has not been properly evaluated during long-term antiviral therapy in chronic hepatitis B (CHB) patients. In this study, liver stiffness was serially performed by FibroScan every 26 weeks in a prospective cohort of CHB patients receiving entecavir. Results were compared with liver biopsies at baseline and week 78.

Longitudinal monitoring of liver stiffness by acoustic radiation force impulse imaging in patients with chronic hepatitis B receiving entecavir.

Background: Acoustic radiation force impulse (ARFI) imaging measures liver stiffness (LS), which significantly correlates with the stage of liver fibrosis in treatment-naive patients with chronic hepatitis B (CHB).

Aim: We aimed to prospectively assess the clinical usefulness of ARFI during long-term antiviral therapy in CHB.

Method: Seventy-one CHB patients were consecutively recruited and paired liver biopsies were performed in 27 patients.

HMGB1-induced autophagy: a new pathway to maintain Treg function during chronic hepatitis B virus infection.

High-mobility group box-1 (HMGB1) protein, as one of the well-known damage-associated molecular pattern molecules (DAMPs), is enriched in chronic hepatitis B virus (HBV) infection and has a context-dependent role in autophagy, a highly conserved self-digestive process in response to environmental stress. Recent mouse studies indicate that autophagy is highly active in regulatory T (Treg)-cells. In the present study, we evaluated spontaneous and induced autophagy of peripheral Treg cells from 98 patients with chronic hepatitis B (CHB), by measuring levels of lipidated form of microtubule-associated light chain 3 (LC3-II, marker for closed autophagosomes) and observing autophagic vacuoles (AV) with transmission electron microscope.

IL-10-producing regulatory B-cells suppressed effector T-cells but enhanced regulatory T-cells in chronic HBV infection.

Non-specific immune responses to antigens have been demonstrated as being enhanced during chronic hepatitis B virus (HBV) infection. Here, we evaluated the role of interleukin-10 (IL-10)-producing regulatory B-cells (Bregs) in the pathogenesis of HBV-related liver fibrosis (HBV-LF) and assessed their immunoregulatory effects. Sixty-seven patients diagnosed with chronic hepatitis B (CHB) were enrolled in this study.

Indole-3-Carbinol (I3C) and its Major Derivatives: Their Pharmacokinetics and Important Roles in Hepatic Protection.

Background: Indoles, including indole-3-carbinol (I3C) and its derivatives, are the products of glucosinolate hydrolysis catalyzed by the enzyme myrosinase. Under acidic conditions, I3C polymerizes into 3, 3- diindolylmethane (DIM), [2-(indol-3-ylmethyl)-indol-3-yl]indol-3-ylmethane (LTr1), 1-(3-hydroxymethyl)- indolyl-3-indolylmethane (HI-IM) and indolo[3,2b]carbazole (ICZ). Recently, I3C and its dimer DIM have shown pleiotropic protective effects on chronic liver injuries, including viral hepatitis, hepatic steatosis, hepatic cirrhosis, hepatocellular carcinoma, and so on.

Restoring homeostasis of CD4⁺ T cells in hepatitis-B-virus-related liver fibrosis.

Immune-mediated liver injury is widely seen during hepatitis B virus (HBV) infection. Unsuccessful immune clearance of HBV results in chronic hepatitis and increases the risk of liver cirrhosis and hepatocellular carcinoma. HBV-related liver fibrosis (HBVLF), occurring as a result of HBV-induced chronic hepatitis, is a reversible, intermediate stage of chronic hepatitis B (CHB) and liver cirrhosis.
