Background/aim: Despite advances in oral squamous cell carcinoma (OSCC) diagnosis and treatment, the five-year survival rate remains low, underscoring the need for improved biomarkers and therapeutic strategies. This study investigated the role of let-7d-5p microRNA (miRNA) and its target gene OLR1 in OSCC, focusing on their implications in tumor progression, metastasis and potential as therapeutic targets.

Materials And Methods: Employing next-generation sequencing and bioinformatic tools, we profiled differentially expressed miRNAs in metastatic OSCC cell lines, identifying let-7d-5p as a key down-regulated miRNA and OLR1 as a novel target of let-7d-5p.

Article Synopsis
  • Ovarian cancer is highly lethal due to late diagnosis and ineffective treatments, and the role of the tumor microenvironment in cancer progression is not fully understood.
  • Research identified periostin (POSTN), a protein found in higher levels in aggressive ovarian cancer cells, which plays a key role in promoting tumor growth and metastasis through specific signaling pathways.
  • Experimental studies demonstrated that higher POSTN levels lead to increased cancer cell migration and invasion, as well as enhanced attraction of immune cells, specifically M2 macrophages, contributing to tumor spreading.

Background: Targeting the HGF/MET signaling pathway has been a viable therapeutic strategy for various cancer types due to hyperactivation of HGF/MET axis occurs frequently that leads to detrimental cancer progression and recurrence. Deciphering novel molecule mechanisms underlying complex HGF/MET signaling network is therefore critical to development of effective therapeutics for treating MET-dependent malignancies.

Results: Using isobaric mass tag-based quantitative proteomics approach, we identified IFITM3, an interferon-induced transmembrane protein that was highly expressed in micro-dissected gastric cancer (GC) tumor regions relative to adjacent non-tumor epithelia.

Article Synopsis
  • Drug resistance in oral squamous cell carcinoma (OSCC) is a major challenge, with cancer stem cells (CSCs) playing a critical role in recurrence and metastasis, making the understanding and targeting of CSCs essential for improving treatment outcomes.
  • In the study, various molecular techniques were employed to specifically target keratin 17 (KRT17) in OSCC cells, which were assessed for their growth, stemness, and invasive characteristics through functional assays and a mouse tumor model.
  • Results showed that high KRT17 expression is linked to increased invasiveness and poor survival in OSCC, while knocking down KRT17 reduced stemness traits and led to the identification of a novel signaling pathway that promotes cancer cell progression.

Triple negative breast cancer (TNBC) possesses poor prognosis mainly due to lack of effective endocrine or targeted therapies, aggressive nature and high rate of chemoresistance. Cancer stem cells (CSCs) are considered to play critical roles in cancer recurrence and chemoresistance. THEMIS2 was identified as the sole common elevated gene in three triple negative breast cancer (TNBC) and two ovarian CSC lines.

Triple negative breast cancer (TNBC) possesses poor prognosis mainly due to development of chemoresistance and lack of effective endocrine or targeted therapies. MiR-491-5p has been found to play a tumor suppressor role in many cancers including breast cancer. However, the precise role of miR-491-5p in TNBC has never been elucidated.

Hepatocellular carcinoma (HCC) is the third leading cause of cancer deaths worldwide, affecting over 700,000 people per year. The treatment effect in advanced HCC is still disappointing and prognosis of advanced HCC remains poor. Hence, to find more effective therapeutic targets to improve the treatment outcome of HCC is of urgent need.

Article Synopsis
  • Targeting the c-Met signaling pathway shows promise for treating oral squamous cell carcinoma (OSCC) by revealing a new regulatory mechanism involving keratin 16 (KRT16).
  • High levels of KRT16 in OSCC correlate with worse patient outcomes and contribute to tumor aggressiveness and resistance to treatment.
  • Research suggests that modulating the miR-365-3p/EHF/KRT16/β5-integrin/c-Met pathway can enhance cancer treatment effectiveness, especially when combined with existing therapies like 5-fluorouracil (5-FU).

Background: Hepatocellular carcinoma (HCC) is the second leading cause of cancer-related death worldwide. The disease recurrent rate is relatively high resulted in poor 5-year survival in advanced HCC. Cancer stem cells (CSCs) have been considered to be one of the main mechanisms for chemoresistance, metastasis, and recurrent disease.

The early onset breast cancer patients (age ≤ 40) often display higher incidence of axillary lymph node metastasis, and poorer five-year survival than the late-onset patients. To identify the genes and molecules associated with poor prognosis of early onset breast cancer, we examined gene expression profiles from paired breast normal/tumor tissues, and coupled with Gene Ontology and public data base analysis. Our data showed that the expression of GAS7b gene was lower in the early onset breast cancer patients as compared to the elder patients.

Breast cancer subtypes can be stratified by IHC expression of estrogen receptor, progesterone receptor, and human epidermal growth factor 2 (HER2). The signaling pathways mediated by these receptors are the dominant drivers of cell proliferation and survival in most human breast cancers. One of the most frequently overactivated pathways in breast cancer is the AKT signaling cascade.

Pulmonary function in 42 patients with chronic myelogenous leukemia (CML) was tested before and after HLA-matched (39 related, 3 unrelated) allogeneic bone marrow transplantation (BMT) between 1985 and 1999. Pulmonary function tests (PFTs) including ventilatory capacity, lung volumes, and diffusion capacity for carbon monoxide (DLCO) were performed before and 3, 6, 12, and 24 months after BMT, and every 12 months thereafter. Possible pre- and post-BMT risk factors were evaluated for their influence on pulmonary function.
