Summary: In non-transformed human squamous epithelial cells, the decision of whether to arrest or undergo apoptosis in response to stress is mediated by the interaction between p53 and the zinc-finger transcription factor KLF5. The levels of cellular stress determine the specific outcome, with moderate stress leading to cell survival and severe stress resulting in apoptosis.

Summary: A study identified DANCR, a long noncoding RNA, as a promoter of cisplatin chemoresistance in triple-negative breast cancer cells. It was found that DANCR binds to KLF5 and induces acetylation of KLF5, resulting in down-regulation of KLF5 and hypersensitivity to cisplatin through the DANCR/KLF5/p27 signaling pathway.

Summary: Ubiquitin-specific protease (USP)19 is a deubiquitinating enzyme that regulates protein stability and function, with its alternative splicing resulting in two major variants localized to the endoplasmic reticulum and cytoplasm. USP19-CY promotes TGF-beta signaling by interacting with the TGF-beta type I receptor and preventing its degradation at the plasma membrane, while USP19-ER sequesters the receptor in the ER and inhibits TGF-beta/SMAD signaling. Increased USP19-CY expression is associated with poor prognosis and higher levels in breast cancer tissues, where it enhances epithelial-mesenchymal transition and cell migration. Modulating USP19 splicing or deubiquitinating activity may hold therapeutic potential for breast cancer.

Summary: The study evaluated the clinical value, biological function, and underlying mechanisms of the Cell division cycle associated 5 (CDCA5) in epithelial ovarian cancer (EOC). CDCA5 was found to be upregulated in EOC and correlated with adverse clinicopathological characteristics and poor prognosis. CDCA5 promoted proliferation, invasion, and metastasis while inhibiting apoptosis in EOC cells through the activation of the cell cycle pathway and inhibition of the P53 pathway. Knockdown of CDCA5 expression inhibited malignant activities of EOC cells and suppressed tumor growth in vivo. Mechanistically, the transcription factor KLF5 promoted CDCA5 expression by binding to the CDCA5 promoter. KLF5 overexpression rescued the negative regulation of CDCA5 expression on EOC cell proliferation.

Summary: ATF3 is significantly upregulated in keloid tissues, promoting cell proliferation and collagen production while reducing apoptosis rate. ATF3 enhances growth and invasion, inhibits apoptosis through the TGF-beta/Smad pathway in keloid fibroblast cells, suggesting its potential as a therapeutic target for keloid management.

Summary: The study investigated the effects of misregulated Fbw7 substrates on colorectal cancer cells using RNA-Seq and high-resolution mapping techniques. The findings revealed widespread transcriptional changes and altered transcription factor occupancy caused by Fbw7 mutations. Additionally, Fbw7 loss was associated with increased expression of MHC Class II genes such as CIITA.

Summary: Cancer is the second leading cause of death globally. MYC plays a critical role in cancer cell growth, but drugs targeting MYC are difficult to obtain. A protein called MTBP has been found to be associated with MYC and helps its pro-growth and cancer-promoting function. Elevated levels of MTBP in cancer are associated with reduced patient survival. Decreasing MTBP levels can inhibit cancer cell growth and induce cancer cell death, suggesting that MTBP may represent a new cancer drug target.

Summary: It has been shown that Tbx18-positive cells contribute to the development of the urinary system, particularly renal fibroblasts. Under pathological conditions induced by UUO, Tbx18-positive cells may act as profibrotic progenitors, with TGF-beta potentially playing a role in their differentiation into myofibroblasts in kidney fibrosis.

Summary: Cell density impacts gene expression and differentiation in mouse embryonic stem cells; β-catenin is primarily at adherens junctions at high density but translocates to the nucleus at low density; Esrrb maintains pluripotency gene expression at high density and decreases DNA association at low density.

Summary: Therapies for bone metastatic prostate cancer are limited and the underlying mechanisms are unclear. Research shows that bone-derived TGF-beta induces acetylation of KLF5, which promotes prostate cancer bone metastasis and resistance to docetaxel.

Summary: In renal cell carcinoma (RCC), the interaction between long non-coding RNA (lncRNA) HOTAIR and androgen receptor (AR) forms a feedback loop that promotes tumor angiogenesis, with HOTAIR enhancing GLI2 expression by cooperatively binding to its promoter with AR. These findings suggest that HOTAIR and GLI2 could serve as novel therapeutic targets against RCC.

Summary: Molecular signatures predictive of recurrence-free survival and castration resistance in prostate cancer are crucial for treatment decisions, but current signatures have limited robustness. By analyzing 287 differentially expressed genes, a 6-gene signature called CRPC-derived prognosis signature (CRPCPS) was identified to predict recurrence-free survival and distinguish between castration-resistant and hormone-sensitive prostate cancer. The robustness of this signature was demonstrated in multiple cohorts, showing its potential clinical utility.

Summary: Prostate cancer is a major cause of cancer-related deaths among men, requiring novel treatments. Deslanoside has shown anticancer activity in prostate cancer cells by modulating gene expression, inducing cell cycle arrest at G2/M, and promoting apoptosis. The altered expression of specific genes by deslanoside also correlates with survival outcomes in prostate cancer patients, suggesting potential for its repurposing as an anticancer drug.

Summary: This study compares the efficacy of ALA-450 nm PDT and ALA-635 nm PDT and finds that ALA-450 nm PDT is more effective in inhibiting cell proliferation and promoting cell apoptosis than ALA-635 nm PDT, possibly through increasing intracellular ROS generation and caspase-dependent apoptosis pathway. In addition, ALA-450 nm PDT significantly inhibits tumor growth and activates cell apoptosis. Therefore, ALA-450 nm PDT may be a promising therapeutic strategy for eradicating HR-HPV infected cells and HR-HPV related diseases.
