MPCD Index for Hepatocellular Carcinoma Patients Based on Mitochondrial Function and Cell Death Patterns.

Hepatocellular carcinoma (HCC) is a highly heterogeneous cancer with a poor prognosis. During the development of cancer cells, mitochondria influence various cell death patterns by regulating metabolic pathways such as oxidative phosphorylation. However, the relationship between mitochondrial function and cell death patterns in HCC remains unclear.

Background: Patients with estrogen receptor (ER)-positive breast cancer (BC) can be treated with endocrine therapy targeting ER, however, metastatic recurrence occurs in 25% of the patients who have initially been treated. Secreted proteins from tumors play important roles in cancer metastasis but previous methods for isolating secretory proteins had limitations in identifying novel targets.
Methods: We applied an in situ secretory protein labeling technique using TurboID to analyze secretome from tamoxifen-resistant (TAMR) BC.
Orthogonal-Group-Controlled Site-Selective I-Branching of Poly-N-acetyllactosamine Chains Reveals Unique Binding Specificities of Proteins towards I-Antigens.

Poly-N-acetyllactosamine (poly-LacNAc) is ubiquitously expressed on cell surface glycoconjugates, serving as the backbone of complex glycans and an extended scaffold that presents diverse glycan epitopes. The branching of poly-LacNAc, where internal galactose (Gal) residues have β1-6 linked N-acetylglucosamine (GlcNAc) attached, forms the blood group I-antigen, which is closely associated with various physiological and pathological processes including cancer progression. However, the underlying mechanisms remain unclear as many of the I-antigen sequences are undefined and inaccessible.

In this study, we explored the intricate relationship between Pannexin 1 (PANX1) and the Hippo signaling pathway effector, Yes-associated protein (YAP). Analysis of The Cancer Genome Atlas (TCGA) data revealed a significant positive correlation between PANX1 mRNA and core Hippo components, Yes-associated protein 1 [YAP], Transcriptional coactivator with PDZ-binding motif [TAZ], and Hippo scaffold, Ras GTPase-activating-like protein IQGAP1 [IQGAP1], in invasive cutaneous melanoma and breast carcinoma. Furthermore, we demonstrated that PANX1 expression is upregulated in invasive melanoma cell lines and is associated with increased YAP protein levels.

Objective: Gastrointestinal (GI) cancers account for one-third of global cancer mortality, with nearly half being preventable. This study updates the global burden of GI cancers attributed to major risk factors: smoking, alcohol, and metabolic disturbances.
Methods: We utilized data from the Global Burden of Disease Study 2021 to examine trends in death and age-standardized death rates related to GI cancers caused by smoking, alcohol, high body mass index (BMI), and high fasting blood glucose (FBG) from 2000 to 2021.
