Oncogenic cell-surface membrane proteins contribute to the phenotypic and functional characteristics of cancer stem cells (CSCs). We employed a proximity-labeling proteomic approach to quantitatively analyze the cell-surface membrane proteins in close proximity to CD147 in CSCs. Furthermore, we compared CSCs to non-CSCs to identify CSC-specific cell-surface membrane proteins that are closely interact with CD147 and revealed that lateral interaction between CD147 and CD276 concealed within the lipid raft microdomain in CSCs, confers resistance to docetaxel, a commonly used chemotherapy agent for various cancer types, including metastatic breast cancer.

Article Synopsis
  • Ribosomal protein L17 (RPL17) is found to be up-regulated in colorectal cancer (CRC), signaling a potential role in cancer progression that has not been previously studied.
  • The research utilized RPL17-specific siRNAs to silence its expression in CRC cells, leading to decreased cell growth, reduced colony formation, and suppressed tumor formation in mouse models.
  • Molecular analyses revealed that RPL17 silencing down-regulated key proteins associated with cell proliferation and stemness, suggesting it plays an oncogenic role in CRC by enhancing tumor cell survival and invasive capabilities.

Background: Tumor necrosis factor-α (TNF-α) is an immunostimulatory cytokine that is consistently high in the breast tumor microenvironment (TME); however, its differential role in mitochondrial functions and cell survival in ER/PR +ve and ER/PR -ve breast cancer cells is not well understood.

Methods: In the current study, we investigated TNF-α modulated mitochondrial proteome using high-resolution mass spectrometry and identified the differentially expressed proteins in two different breast cancer cell lines, ER/PR positive cell line; luminal, MCF-7 and ER/PR negative cell line; basal-like, MDA-MB-231 and explored its implication in regulating the tumorigenic potential of breast cancer cells. We also compared the activity of mitochondrial complexes, ATP, and ROS levels between MCF-7 and MDA-MB-231 in the presence of TNF-α.

Gonorrhea is one of the most common, but still hidden and insidious, sexually transmitted diseases caused by (). However, the diagnosis and treatment of gonorrhea are hampered by antigenic variability among , the lack of acquired immunity, and antimicrobial resistance. Further, strains resistant to cephalosporins, including ceftriaxone, the last line of defense, represent a growing threat, which prompted us to develop -specific diagnostic antibodies with broad-spectrum binding to strains to generate gonorrhea-detecting reagents.

Article Synopsis
  • Big data analysis identified CDCA8 as increasingly active in human hepatocellular carcinoma (HCC), correlating with poorer survival outcomes, but its specific role in HCC development is still unclear.
  • Experimental results showed that reducing CDCA8 levels slows down HCC cell growth, colony formation, and migration by causing cell cycle arrest at the G2/M phase, while increasing CDCA8 levels does the opposite.
  • CDCA8 influences several genes and proteins, including increasing tumor-suppressive proteins and inhibiting oncogenic pathways in CD133 cancer stem cells, suggesting that targeting CDCA8 could be a promising strategy for HCC treatment and recurrence prevention.

Post-translational modifications, including -GlcNAcylation, play fundamental roles in modulating cellular events, including transcription, signal transduction, and immune signaling. Several molecular targets of -GlcNAcylation associated with pathogen-induced innate immune responses have been identified; however, the direct regulatory mechanisms linking -GlcNAcylation with antiviral RIG-I-like receptor signaling are not fully understood. In this study, we found that cellular levels of -GlcNAcylation decline in response to infection with Sendai virus.
