Patients with inflammatory bowel disease (IBD), including ulcerative colitis (UC), show an increased incidence of anxiety and depression; however, the association between UC-associated psychiatric disorders and the gut microbiota is unclear. This study aimed to examine whether gut microbiota from patients with UC can alter colonic gene expression, leading to anxiety- and depression-like behavior in mice receiving fecal microbiota transplantation (FMT). RNA sequencing transcriptome analyses revealed a difference in colonic gene expression between mice receiving FMT from patients with UC (UC-FMT mice) and those receiving FMT from healthy controls (HC-FMT mice).

Article Synopsis
  • The immune environment in tumors has opened new possibilities for cancer treatment, but the neural environment around tumors is often neglected despite its role in cancer progression.
  • Neurotrophic factors released by cancer cells help nerve cells infiltrate the tumor microenvironment, promoting cancer cell growth, migration, and invasion via neurotransmitters.
  • Certain components of the neural circuits in cancers may serve as biomarkers for cancer aggressiveness; targeting them with inhibitors could reduce cancer morbidity and mortality, but more research is needed to assess the effectiveness of anti-neurogenic agents in therapy.

Ovarian cancer is a metastatic disease that frequently exhibits extensive peritoneal dissemination. Recent studies have revealed that noncancerous cells inside the tumor microenvironment, such as macrophages and mesothelial cells, may play a role in ovarian cancer metastasis. In this study, we found that human ovarian cancer cells (A2780 and SKOV3) adhered more to human mesothelial Met5A cells stimulated by macrophages (M-Met5A) in comparison to unstimulated control Met5A cells.

Article Synopsis
  • Tumor cells secrete cytokines like CCL2, influencing both their own behavior and neighboring cells, which can lead to treatment resistance.
  • Human ovarian cancer cells showed resistance to the drug paclitaxel after exposure to conditioned medium from other resistant cells, with high levels of CCL2 being linked to poorer patient outcomes.
  • Targeting the CCL2/CCR2 signaling pathway may enhance paclitaxel sensitivity in ovarian cancer by mitigating chemoresistance and reducing macrophage migration that supports cancer cell survival.

The present study demonstrated that 2'-hydroxycinnamaldehyde (2'-HCA) induced apoptosis in human promyelocytic leukemia HL-60 cells through the activation of mitochondrial pathways including (1) translocation of Bim and Bax from the cytosol to mitochondria, (2) downregulation of Bcl-2 protein expression, (3) cytochrome release into the cytosol, (4) loss of mitochondrial membrane potential (Δ), and (5) caspase activation. 2'-HCA also induced the activation of c-Jun N-terminal kinase (JNK) and extracellular signal-regulated kinase1/2 (ERK1/2) in HL-60 cells. The pharmacological and genetic inhibition of JNK effectively prevented 2'-HCA-induced apoptosis and activator protein-1 (AP-1)-DNA binding.
