Combined spatially resolved metabolomics and spatial transcriptomics reveal the mechanism of RACK1-mediated fatty acid synthesis.

Lipid metabolism is altered in rapidly proliferating cancer cells, where fatty acids (FAs) are utilized in the synthesis of sphingolipids and glycerophospholipids to produce cell membranes and signaling molecules. Receptor for activated C-kinase 1 (RACK1; also known as small ribosomal subunit protein) is an intracellular scaffolding protein involved in signaling pathways. Whether such lipid metabolism is regulated by RACK1 is unknown.

Local membrane source gathering by p62 body drives autophagosome formation.

Autophagosomes are double-membrane vesicles generated intracellularly to encapsulate substrates for lysosomal degradation during autophagy. Phase separated p62 body plays pivotal roles during autophagosome formation, however, the underlying mechanisms are still not fully understood. Here we describe a spatial membrane gathering mode by which p62 body functions in autophagosome formation.

Receptor for activated C kinase 1 promotes cervical cancer lymph node metastasis via the glycolysis‑dependent AKT/mTOR signaling.

Cervical cancer (CC), an aggressive form of squamous cell carcinoma, is characterized by early‑stage lymph node metastasis and an extremely poor prognosis. The authors have previously demonstrated that patients with CC have aberrant glycolysis. The upregulation of receptor for activated C kinase 1 (RACK1) is associated with CC lymph node metastasis (LNM).

CXCL10 Produced by HPV-Positive Cervical Cancer Cells Stimulates Exosomal PDL1 Expression by Fibroblasts CXCR3 and JAK-STAT Pathways.

Persistent infection with human papillomavirus (HPV) and immune surveillance failure may be the initiating factors for the carcinogenesis of cervical squamous cell carcinoma (CSCC). HPV infection might affect the innate immune pathway of cervical epithelial cells that constitute the "microenvironment" for tumor cells. Programmed death-ligand 1 (PD-L1) has been reported to be an immunosuppressor that helps cancer cells escape the actions of T cells.

CD147 promotes cervical cancer migration and invasion by up-regulating fatty acid synthase expression.

CD147 is a transmembrane glycoprotein that when highly expressed contributes to tumor progression. In the present study, we investigate the clinical relevance of CD147 expression in CCSC tissues and evaluate the association between CD147 expression and cervical lymph node metastasis; CD147 was detected using immunohistochemistry. To functionally analyze the role of CD147 in CCSC cell lines in vitro, SiHa cells were employed, whose endogenous CD147 was artificially downregulated, by using lentiviral-based transfection.

SIRT3 promotes the invasion and metastasis of cervical cancer cells by regulating fatty acid synthase.

Sirtuin 3 (SIRT3) modulates mitochondria-localized processes and is implicated in the metabolic reprogramming of cancer cells, especially fatty acid (FA) synthesis. However, the relationship between SIRT3 and aberrant lipid synthesis in cervical cancer remains unclear. Here, we investigated the clinical relevance of SIRT3 expression in cervical squamous cell carcinoma (CSCC), cervical intraepithelial neoplasia (CIN), and normal tissues.

Characterization of a novel MICB variant in an individual from the Chinese Uyghur population, MICB*005:09, by cloning and sequencing.

A new allelic variant in MICB*005 lineage, MICB*005:09, has been identified in a male Uyghur individual recruited from Xinjiang Uyghur Autonomous Region, China by PCR-sequence-based typing (Sanger sequencing) and confirmed by cloning and sequencing. Aligned with MICB*005:03, this new allelic variant shows a synonymous T substitution at nucleotide position 8 in exon 2, corresponding to codon 3 (CAC→CAT) of the mature MICB mRNA transcript.

High MLL2 expression predicts poor prognosis and promotes tumor progression by inducing EMT in esophageal squamous cell carcinoma.

Background: MLL2 has been identified as one of the most frequently mutated genes in a variety of cancers including esophageal squamous cell carcinoma (ESCC). However, its clinical significance and prognostic value in ESCC has not been elucidated. In the present study, we aimed to investigate the expression and role of MLL2 in ESCC.

RNF113A promotes the proliferation, migration and invasion, and is associated with a poor prognosis of esophageal squamous cell carcinoma.

Ring finger protein 113A (RNF113A) possesses a C3HC4 zinc finger domain and this domain is found in E3 ubiquitin ligase and is involved in tumorigenesis. To date, and at least to the best of our knowledge, there are no studies available which have investigated RNF113A in cancer. Thus, this study aimed to explore the role of RNF113A in the development of esophageal squamous cell carcinoma (ESCC).

Over-expression of prolyl isomerase Pin1 promotes cervical tumorigenesis and metastasis.

Overexpression of the prolyl isomerase PIN1 is involved in tumorigenesis, but the role of PIN1 in cervical cancer is unclear. In this study, we examined PIN1 protein expression by immunohistochemistry in 221 paraffin-embedded samples from cervical cancer patients, cervical intraepithelial neoplasia patients, and control tissues, and found that high expression of PIN1 was significantly associated with lymph node metastasis (P=0.002), advanced stage according to the International Federation of Gynecology and Obstetrics guidelines (P=0.

Expression, prognosis and functional role of Thsd7a in esophageal squamous cell carcinoma of Kazakh patients, Xinjiang.

Thsd7a (Thrombospondin type 1 domain containing 7a) is a critical transmembrane protein. Studies have indicated that Thsd7a was associated with cytoskeletal organization, cell migration and filopodia formation. However, the involvement of Thsd7a remains elusive in human Esophageal Squamous Cell Carcinoma (ESCC).

Nuclear factor erythroid-2-related factor 2 (NFE2L2) is a transcription factor associated with resistance to chemotherapy and increased tumor growth. NRF2 is repressed by the inhibitor Keap1. The Keap1-NRF2 pathway is dysfunctional in multiple tumor types.

Epigenetic changes within the promoter regions of antigen processing machinery family genes in Kazakh primary esophageal squamous cell carcinoma.

The esophageal squamous cell carcinoma (ESCC) is thought to develop through a multi-stage process. Epigenetic gene silencing constitutes an alternative or complementary mechanism to mutational events in tumorigenesis. Posttranscriptional regulation of human leukocyte antigen class I (HLA-I) and antigen processing machinery (APM) proteins expression may be associated with novel epigenetic modifications in cancer development.

However, association of this deficiency with cervical cancer and precancerous lesions are still not definitively known.
