The FoxM1 transcription factor plays an important role in the progression of HCC. Therefore, it is necessary to study cell regulation of FoxM1. In this study, we determined the expression of miR-214 and it was inversely associated with FoxM1 protein level in HCC; and suppression of FoxM1 translation by miR-214 mimics. We found that miR-214 targeted the 3'untranslated region of FoxM1 mRNA. In addition, the study found that DLX1 was the direct target of FoxM1 in HCC. Downregulation of FoxM1 inhibits the proliferation, migration, and invasion of HCC cells by miR-214. These results indicate that miR-214 may be used as a completely new molecular target by influencing FoxM1 expression in HCC.

Aim: This study aimed to identify the genes associated with the development of lung adenocarcinoma (LUAD) and potential therapeutic targets.
Methods: Differentially expressed genes (DEGs) were identified by self-transcriptome sequencing of tumor tissues and paracancerous tissues resected during surgery and combined with The Cancer Genome Atlas (TCGA) data to screen for the genes associated with LUAD prognosis. The expression was validated at mRNA and protein levels, and the gene knockdown was used to examine the impact and underlying mechanisms on lung cancer cells.
Colorectal carcinoma (CRC) progression is associated with an increase in PROX1+ tumor cells, which exhibit features of CRC stem cells and contribute to metastasis. Here, we aimed to provide a better understanding to the function of PROX1+ cells in CRC, investigating their progeny and their role in therapy resistance. PROX1+ cells in intestinal adenomas of ApcMin/+ mice expressed intestinal epithelial and CRC stem cell markers, and cells with high PROX1 expression could both self-renew tumor stem/progenitor cells and contribute to differentiated tumor cells.

Cancer immunotherapy has revolutionized cancer treatment by harnessing the body's immune system to recognize and attack tumors. Over the past 25 years, the use of blocking antibodies has fundamentally transformed the landscape of cancer therapy. However, despite extensive research, agonist antibodies targeting costimulatory receptors such as ICOS, GITR, OX40, CD27, and 4-1BB have consistently underperformed in clinical trials over the past 15 years, failing to meet the anticipated success.

While there is growing evidence highlighting the crucial role of the BM microenvironment (BMME) in MDS, the specific influence of inflammation on BMME changes, as well as the potential benefits of targeting cytokines therapeutically, remain to be elucidated. We previously found interleukin-1 (IL-1) to be a driver of aging phenotypes of BMME and hematopoietic stem and progenitor cells (HSPCs).

Marek's disease virus (MDV), a highly contagious and oncogenic avian alphaherpesvirus, establishes a latent infection primarily in CD4 T cells. Latent infections are necessary for both persistent lifelong MDV infection and viral tumorigenesis. MicroRNAs (miRNAs) play critical roles as post-transcriptional regulators of viral infections.
