Impact of glycolysis enzymes and metabolites in regulating DNA damage repair in tumorigenesis and therapy.

Initially, it was believed that glycolysis and DNA damage repair (DDR) were two distinct biological processes that independently regulate tumor progression. The former metabolic reprogramming rapidly generates energy and generous intermediate metabolites, supporting the synthetic metabolism and proliferation of tumor cells. While the DDR plays a pivotal role in preserving genomic stability, thus resisting cellular senescence and cell death under both physiological and radio-chemotherapy conditions.

SULT2B1: a novel therapeutic target in colorectal cancer via modulation of AKT/PKM2-mediated glycolysis and proliferation.

Background: Sulfotransferase family 2B member 1 (SULT2B1) is involved in regulating cell proliferation, migration and metabolism. However, there is still dispute regarding whether SULT2B1 acts as an oncogene or a suppressor, and the intrinsic mechanisms in modulating tumor progression need to be further elucidated.

Methods: This work aims to reveal the relationship among SULT2B1, AKT, PKM2 signaling and glycolytic pathways, and provided a theoretical basis for SULT2B1 as a potential therapeutic target for CRC.

CCT6A functions as promising diagnostic biomarker and promotes cell proliferation in colorectal cancer.

: Chaperonin-containing tailless complex polypeptide 1 subunit 6A (CCT6A) is mainly located in the cytoplasm and considered to be involved in various biological processes in tumors. However, its function and the intrinsic mechanism need to be further elucidated. : Multi-omics analysis was used to evaluate the correlation between CCT6A expression and prognosis of patients, as well as its immune value.

PFKFB3 deprivation attenuates the cisplatin resistance via blocking its autophagic elimination in colorectal cancer cells.

Introduction: 6-Phosphofructo-2-kinase/fructose-2,6-bisphosphatase isoform 3 (PFKFB3) is highly expressed in several cancers and plays important roles during the whole pathological process of cancer. It is also involved in chemoresistance, while the intrinsic mechanism needs to be further revealed.

Methods: The different responses to cisplatin (DDP) between wild type (WT) and DDP-resistant (DDR) colorectal cancer (CRC) cells were analyzed by several assays.

GNL3L promotes autophagy via regulating AMPK signaling in esophageal cancer cells.

Guanine nucleotide-binding protein-like 3-like (GNL3L), a conserved GTP-binding nucleolar protein, participates in regulating cell proliferation, and associates with tumorigenesis and poor prognosis in several kind of cancers. However, the role of GNL3L in modulating autophagy remains unclear. Here, we verified that GNL3L was higher expressed in esophageal cancer (ESCA) biopsies than that in the corresponding normal biopsies by a human ESCA tissue array.
