Summary: Metallothionein-2 plays a crucial role in oxaliplatin-induced neuropathic pain and may serve as a potential target for the prevention and treatment of CIPN. Genetic restoration of metallothionein-2 can block and reverse neuropathic pain, while inhibition of metallothionein-2 can trigger pain. Enhancing transcription of I kappa B-alpha promoter by reducing NF-kappa B activation and inflammatory responses is proposed as a mechanism.

Summary: Hypoxia is extensively studied for its impact on various pathophysiological processes such as cancer progression. The contribution of miRNAs to molecular response to hypoxia varies significantly depending on cell types and causes of hypoxia. The regulatory network induced by hypoxia is complex and plays a crucial role in tumor progression.

Summary: Aberrant activation of endoplasmic reticulum (ER) stress by intrinsic and extrinsic factors contributes to tumor initiation and chemoresistance in various cancers. Downregulation of PHLPP in colon cancer cells, induced by ER stress, upregulates autophagy-associated genes through the eIF2 alpha/ATF4 signaling axis, resulting in increased resistance to chemotherapy.

Summary: Hematopoietic stem cells (HSCs) show impaired recovery and self-renewal, as well as increased differentiation, when exposed to ambient air. The mechanism behind this distinction involves upregulation of HSC self-renewal genes, downregulation of genes involved in inflammatory pathways and HSC differentiation, and downregulation of the epigenetic modifier Tet2.

Summary: In this study, the researchers found that eIF3a plays a crucial role in vemurafenib resistance by controlling ERK activity and influencing the sensitivity of melanoma cells to BRAF inhibitors. Furthermore, a positive correlation between eIF3a and PPP2R1B expression was observed in tumor samples, suggesting a potential new strategy for predicting vemurafenib responses in clinical treatment.

Summary: Platelets are increased and activated in the lungs of hypoxic mice, and their depletion prevents hypoxia-driven increases in proinflammatory chemokines CXCL4 and CCL5. The study suggests a potential contribution of platelets to inflammatory mediated vascular remodeling and pulmonary hypertension.

Summary: In this study, the researchers discovered the importance of nc886 gene in prostate cancer, which affects tumor progression and metastasis by changing cellular morphology and promoting epithelial-to-mesenchymal transition (EMT). They found that nc886 promotes MET by facilitating the degradation of SNAIL protein through ubiquitination. Additionally, they revealed that TGF-beta 1 regulates the transcription of nc886 and its neighboring genes through multiple mechanisms, thus further influencing the EMT process.

Summary: Dormant cancer cells in colorectal cancer (CRC) have negative effects on prognosis, leading to cancer recurrence, metastasis, and drug resistance. A recent study revealed that autophagy plays a crucial role in the survival of dormant tumor cells. In this study, the researchers found that downregulation of polo-like kinases 4 (PLK4) induced dormancy and inhibited migration and invasion in CRC cell lines. They also discovered a correlation between PLK4 expression and dormancy markers in clinical samples. Mechanistically, downregulation of PLK4 induced autophagy through the MAPK signaling pathway, contributing to the restoration of aggressive tumor cells to a dormant state.

Summary: Hexavalent chromium is a potent human lung carcinogen, but the molecular mechanisms underlying its carcinogenicity remain unclear. This study found that hedgehog-interacting protein levels were significantly reduced in Cr(VI)-transformed cells, suggesting a potential role of Hedgehog signaling in Cr(VI)-induced malignant transformation. Additionally, abnormal activation of Hedgehog signaling and epigenetic mechanisms were observed in these cells, highlighting a novel regulatory mechanism in Cr(VI)-induced lung carcinogenesis.

Summary: DNA methylation at the promoter CpG islands of CHK gene is increased in colon cancer cells and human colon cancer tissues compared to normal healthy counterparts, leading to decreased expression of CHK mRNA. Enhanced levels of DNMT in colon cancer cells and tissues contribute to this process, resulting in increased oncogenic properties in colon cancer cells.

Summary: This study found that KLF10 was closely related to renal function, tubular injury, and regeneration in various renal diseases through network-based analysis of human kidney transcriptional data. The downregulation of KLF10 in acute kidney injury (AKI) was confirmed in mouse models and correlated with tubular regeneration and AKI outcome. In vitro experiments showed that KLF10 declined in survived cells but increased during tubular formation or conquering proliferative impediment. Overexpression of KLF10 inhibited the capacity of proliferation, injury repairing, and lumen-formation of renal tubular cells, while knockdown of KLF10 promoted these processes. The PTEN/AKT pathway was validated as the downstream of KLF10 in the regulation of tubular regeneration, and ZBTB7A was identified as the upstream transcription factor of KLF10. This study provides insight into the novel therapeutic and diagnostic target of AKI.

Summary: Proximal tubular cells (PTC) are vulnerable to hypoxia-induced apoptosis, which may be a crucial factor in kidney diseases. Research has shown that apoptosis under hypoxia is mediated by COX-2-dependent production of PGE(2), suggesting potential new therapeutic targets for preventing hypoxia-dependent lesions in renal diseases.
