Turning immunologically "cold" tumors "hot" is required for effective immune checkpoint inhibitor (ICI) treatment in hepatocellular carcinoma (HCC). Here, we identified Fas-associated death domain (FADD) as a key molecule upregulated in HCC with dense tumor-infiltrating CD8+ T cells and better response to ICIs. CRISPR-mediated knockout of Fadd in murine HCC cells led to increased tumor weights in immunocompetent, but not immunodeficient, mice.

Background: Genomic screening uncovered interferon-gamma (IFNγ) pathway defects in tumours refractory to immune checkpoint blockade (ICB). However, its non-mutational regulation and reversibility for therapeutic development remain less understood.

Objective: We aimed to identify ICB resistance-associated druggable histone deacetylases (HDACs) and develop a readily translatable combination approach for patients with hepatocellular carcinoma (HCC).

Marine microorganisms are increasingly recognized as primary producers of marine secondary metabolites, drawing growing research interest. Many of these organisms are unculturable, posing challenges for study. Metagenomic techniques enable research on these unculturable microorganisms, identifying various biosynthetic gene clusters (BGCs) related to marine microbial secondary metabolites, thereby unveiling their secrets.

Article Synopsis
  • Gastric intestinal metaplasia (IM) is identified as a precancerous condition linked to a higher risk of stomach cancer, and Weiwei Decoction (WWD) is a traditional Chinese herbal remedy aimed at treating IM.
  • The study aimed to investigate how WWD affects the OLFM4/NOD1/CDX2 signaling pathway in IM, utilizing various laboratory methods including immunohistochemistry and cell models.
  • Results showed that the OLFM4/NOD1/CDX2 pathway is crucial for IM progression, with WWD enhancing gastric tissue health by reducing OLFM4 and increasing NOD1 expression, ultimately leading to decreased CDX2 levels.

Background & Aims: Recent studies demonstrated the importance of fibrosis in promoting an immunosuppressive liver microenvironment and thereby aggressive hepatocellular carcinoma (HCC) growth and resistance to immune checkpoint blockade (ICB), particularly via monocyte-to-monocytic myeloid-derived suppressor cell (M-MDSC) differentiation triggered by hepatic stellate cells (HSCs). We thus aimed to identify druggable targets in these immunosuppressive myeloid cells for HCC therapy.

Methods: M-MDSC signature genes were identified by integrated transcriptomic analysis of a human HSC-monocyte culture system and tumor-surrounding fibrotic livers of patients with HCC.

Massive expansion of immature and suppressive myeloid cells is a common feature of malignant solid tumors. Over-expression of cyclin-dependent kinase 20, also known as cell cycle-related kinase (CCRK), in hepatocellular carcinoma (HCC) correlates with reduced patient survival and low immunotherapy responsiveness. Beyond tumor-intrinsic oncogenicity, here we demonstrated that CCRK is upregulated in myeloid cells in tumor-bearing mice and in patients with HCC.

Introduction: In metabolic engineering and synthetic biology applications, promoters with appropriate strengths are critical. However, it is time-consuming and laborious to annotate promoter strength by experiments. Nowadays, constructing mutation-based synthetic promoter libraries that span multiple orders of magnitude of promoter strength is receiving increasing attention.

Article Synopsis
  • The study investigates how hepatocellular carcinoma (HCC) adapts to resistance against anti-PD-L1 immunotherapies, revealing the importance of tumour microenvironment remodelling.
  • Researchers created resistant HCC models and used advanced techniques like single-cell RNA sequencing to explore the mechanisms of resistance, finding that certain immune cells (MDSCs) grow alongside tumours and suppress the immune response.
  • The research identified a specific pathway involving PPARγ, which enhances VEGF-A production, leading to immune dysfunction and poor patient outcomes, suggesting that targeting this pathway could potentially enhance the effectiveness of immunotherapies.

Here we provide experimental data showing that with a 1,785-bp coding sequence exhibited a function in mediating transport associated with tobacco growth on nutrition. Heterologous expression of in the uptake-defective yeast enabled a growth recovery of the mutant on 0.

As a noninvasive method, circulating tumor cell (CTC) provides ideal liquid biopsy specimens for early cancer screening and diagnosis. CTCs detection in breast cancer is correlated with patient prognosis such as disease-free survival (DFS) and overall survival (OS). Besides, accumulating evidence supported that CTCs count may be indicator for chemotherapy response as well.

Histone deacetylases (HDACs) are epigenetic regulators and additionally control the activity of non-histone substrates. We recently demonstrated that inhibition of HDAC8 overexpressed in various of cancers reduces hepatocellular carcinoma tumorigenicity in a T cell-dependent manner. Here, we present alkylated hydrazide-based class I HDAC inhibitors in which the -hexyl side chain attached to the hydrazide moiety shows HDAC8 selectivity .

There is a wide variety of kinds of lipids, and complex structures which determine the diversity and complexity of their functions. With the basic characteristic of water insolubility, lipid molecules are independent of the genetic information composed by genes to proteins, which determine the particularity of lipids in the human body, with water as the basic environment and genes to proteins as the genetic system. In this review, we have summarized the current landscape on hormone regulation of lipid metabolism.

Weighted gene co-expression network analysis (WGCNA) identified a cell-cycle module that is associated with poor prognosis and aggressiveness of glioma. One of the core members, Regulator of chromatin condensation 2 (RCC2) is a component of the chromosome passenger complex. Accumulating evidence suggests that RCC2 plays a vital role in the mitotic process and that abnormal RCC2 expression is involved in cancer development.

Obesity is a major risk factor for cancers including hepatocellular carcinoma (HCC) that develops from a background of non-alcoholic fatty liver disease (NAFLD). Hypercholesterolemia is a common comorbidity of obesity. Although cholesterol biosynthesis mainly occurs in the liver, its role in HCC development of obese people remains obscure.

Hepatocellular carcinoma (HCC) is a major cancer burden worldwide with increasing incidence in many developed countries. Super-enhancers (SEs) drive gene expressions required for cell type-specificity and tumor cell identity. However, their roles in HCC remain unclear because of data scarcity from primary tumors.

Breast cancer is one the most common malignancies and leading cause of cancer-related mortality in women. Recent studies suggested that hypercholesterolemia may be the potential modifiable risk factors for breast cancer. Cholesterol was well-known for its strong association with cardiovascular disease for long.

The treatment of recessive dystrophic epidermolysis bullosa (RDEB) remains challenging. Elevated IgE levels have previously been reported in several RDEB patients. In this prospective, single-centre, open intervention study, elevated IgE levels were seen in 11 out of 12 patients with intense pruritus, and the patients with elevated IgE levels received anti-IgE therapy every 4 weeks for at least three cycles.

Insufficient T cell infiltration into noninflamed tumors, such as hepatocellular carcinoma (HCC), restricts the effectiveness of immune-checkpoint blockade (ICB) for a subset of patients. Epigenetic therapy provides further opportunities to rewire cancer-associated transcriptional programs, but whether and how selective epigenetic inhibition counteracts the immune-excluded phenotype remain incompletely defined. Here, we showed that pharmacological inhibition of histone deacetylase 8 (HDAC8), a histone H3 lysine 27 (H3K27)-specific isozyme overexpressed in a variety of human cancers, thwarts HCC tumorigenicity in a T cell-dependent manner.

Mesenchymal stem or stromal cells (MSCs) are nonhematopoietic postnatal stem cells with self-renewal, multipotent differentiation, and potent immunomodulatory and anti-inflammatory capabilities, thus playing an important role in tissue repair and regeneration. Numerous clinical and preclinical studies have demonstrated the potential application of MSCs in the treatment of tissue inflammation and immune diseases, including inflammatory skin diseases. Therefore, understanding the biological and immunological characteristics of MSCs is important to standardize and optimize MSC-based regenerative therapy.
