Unconventional protein secretion (UPS) is a crucial mechanism controlling the localization of cytosolic proteins lacking signal peptides and is implicated in inflammation, neurodegenerative diseases, and cancer. Several previous studies on immune cells have demonstrated the mechanisms of UPS. In cancer, the active secretion of several cytosolic proteins, including PKCδ and nucleolin, has been described. Moreover, we have recently demonstrated that extended synaptotagmin 1, one of the membrane proteins of the endoplasmic reticulum, plays a critical role in UPS in liver cancer cells...

Lysosomes are key organelles that contribute to homeostatic functions such as autophagy-mediated recycling of cellular components and innate immune response through phagocytosis-mediated pathogen killing during infections. Viruses such as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19), has developed unique adaptation to not only avoid lysosome-mediated destruction but also actively utilize lysosomal machinery to both enter and exit cells...

Circular RNA (circRNA) is involved in the occurrence and development of various cancers. To this day, the expression and mechanism of circRNA in osteosarcoma (OS) remain unclear. We previously found that circ_0001060 was highly expressed in OS tumor tissues. In this work, we identified that high level expression of circ_0001060 was significantly associated with late clinical stage, larger tumor volume, higher frequency of metastasis, and poor prognosis in OS patients. Furthermore, we confirmed that silencing circ_0001060 inhibited the proliferation and migration of OS cell...

Compared with other breast cancer subtypes, triple negative breast cancer (TNBC) is an aggressive malignancy with a high recurrence rate and reduced overall survival. Immune checkpoint inhibition (ICI) has shown modest results in this subgroup, highlighting the need for improved targeted therapeutic options. Notch is a defining feature of TNBC and drives the expression of interleukin-1 beta (IL1β) and C-C motif chemokine ligand 2 (CCL2). These cytokines are involved in the recruitment of tumor-associated macrophages (TAMs) to the tumor, resulting in immune evasion and tumor progression...

Improving livestock and poultry growth rates and increasing meat production are urgently needed worldwide. Previously, we produced a myostatin (MSTN) and fibroblast growth factor 5 (FGF5) double-knockout (MF-/- ) sheep by CRISPR Cas9 system to improve meat production, and also wool production. Both MF-/- sheep and the F1 generation (MF+/- ) sheep showed an obvious "double-muscle" phenotype. In this study, we identified the expression profiles of long noncoding RNAs (lncRNAs) in wild-type and MF+/- sheep, then screened out the key candidate lncRNAs that can regulate myogenic differentiation and skeletal muscle development...

Together with an anti-tumor immune response, oncolysis using a recombinant viral vector promises to eliminate cancer cells by both gene transfer and host-mediated functions. In this study we explore oncolysis induced by nonreplicating adenoviral vectors used for p14ARF and interferon-β (hIFNβ) gene transfer in human melanoma cell lines, revealing an unexpected role for p14ARF in promoting cellular responses predictive of immune stimulation. Oncolysis was confirmed when UACC-62 (p53 wild-type) cells succumbed upon p14ARF gene transfer in vitro , whereas SK-Mel-29 (p53-mutant) benefitted from its combination with hIFNβ...
