Leading anti-tumour therapeutic strategies typically involve surgery and radiotherapy for locally advanced (non-metastatic) cancers, while hormone therapy, chemotherapy, and molecular targeted therapy are the current treatment options for metastatic cancer. Despite the initially high sensitivity rate to anticancer therapies, a large number of patients develop resistance, leading to a poor prognosis. The mechanisms related to drug resistance are highly complex, and long non-coding RNAs appear to play a crucial role in these processes. Among these, the lncRNA homeobox transcript antisense intergenic RNA (HOTAIR), widely implicated in cancer initiation and progression, likewise plays a significant role in anticancer drug resistance. It can modulate cell activities such as proliferation, apoptosis, hypoxia, autophagy, as well as epithelial-mesenchymal transition, thereby contributing to the development of resistant tumour cells. In this manuscript, we describe different mechanisms of antitumor drug resistance in which HOTAIR is involved and suggest its potential as a therapeutic predictive biomarker for the management of cancer patients.

Purpose: Mammary carcinoma is comprised heterogeneous groups of cells with different metastatic potential. 4T1 mammary carcinoma cells metastasized to heart (4THM), liver (4TLM) and brain (4TBM) and demonstrate cancer-stem cell phenotype. Using these cancer cells we found thatTGF-β is the top upstream regulator of metastatic process.

Objective: Based on our previous research, which demonstrated that elevated plasma endoglin (ENG) levels in lung cancer patients were associated with a better prognosis, increased sensitivity to pemetrexed, and enhanced tumor suppression, this study aims to validate these findings at the cellular level. The focus is on membrane and extracellular ENG and their influence on drug response and tumor cell behavior in non-small cell lung cancer (NSCLC) cells.
Methods: The correlation between ENG expression and pemetrexed-induced cytotoxicity in eight human non-squamous subtype NSCLC cell lines was analyzed.

Purpose: Alteration of visual acuity in wet age-related macular degeneration (AMD) is mostly driven by vascular endothelial growth factor A (VEGF-A)-induced edema from leaky newly forming blood vessels below the retina layers. To date, all therapies aimed at alleviation of this process have relied on inhibition of VEGF-A activity. Although effective in preventing vascular leak and edema, this approach also leads to the loss of normal vasculature and multiple related side effects.

A major risk to the poultry industry is antimicrobial resistance (AMR), specifically with regard to Mycoplasma gallisepticum (MG) infections. The sensitivity patterns of 100 MG isolates to biocides and antibiotics were examined in this study to clarify the interactions between antimicrobial agents and resistance mechanisms. The antimicrobial activity against MG was assessed using broth microdilution, and the results are shown as the minimum inhibitory concentration (MIC) for each strain, the MIC distribution (range), the MIC, and/or the MIC.
