TMEM166 is a novel programmed cell death-related molecule. In this report, we constructed a recombinant adenovirus 5-TMEM166 vector (Ad5-TMEM166) and evaluated its expression and anti-tumor activities in vitro and in vivo. Cell viability analysis revealed that the adenovirus-mediated increase of TMEM166 inhibited tumor cell growth in a dose- and time-dependent manner. This inhibitory effect was mediated by both autophagy (via inhibition of mTOR and activation of p70S6K) and apoptosis (via caspase-3 activation), both of which contributed to cell death and suppression of tumorigenicity. Our data indicated that Ad5-TMEM166 may be a novel gene therapy candidate for cancer.

Breast cancers of the IntClust-2 type, characterized by amplification of a small portion of chromosome 11, have a median survival of only five years. Several cancer-relevant genes occupy this portion of chromosome 11, and it is thought that overexpression of a combination of driver genes in this region is responsible for the poor outcome of women in this group. In this study we used a gene editing method to knock out, one by one, each of 198 genes that are located within the amplified region of chromosome 11 and determined how much each of these genes contributed to the survival of breast cancer cells.

Background: Our previous research demonstrated that growth differentiation factor 15 (GDF15) exhibited superior predictive capability for metabolic dysfunction-associated steatohepatitis (MASH) development with an AUC of 0.86 at 10 years before disease diagnosis. However, the specific pathways and molecular mechanisms associated with GDF15 expression during MASH development remain to be fully investigated in humans.

The cultivation and differentiation of human embryonic stem cells (hESCs) into organoids are crucial for advancing of new drug development and personalized cell therapies. Despite establishing of chemically defined hESC culture media over the past decade, these media's reliance on growth factors, which are costly and prone to degradation, poses a challenge for sustained and stable cell culture. Here, we introduce an hESC culture system(E6Bs) that facilitates the long-term, genetically stable expansion of hESCs, enabling cells to consistently sustain high levels of pluripotency markers, including NANOG, SOX2, TRA-1-60, and SSEA4, across extended periods.

We aimed to investigate the wound-healing, antioxidant, and anti-inflammatory effects of pterostilbene (PTS) on human gingival fibroblasts (GF). Different concentrations of PTS were applied to GFs and cell viability was evaluated by MTT assay. GFs were stimulated by lipopolysaccharide (LPS) and the study groups were determined as LPS, LPS + 1 μM PTS, LPS + 10 μM PTS, and control.

Throughout the life cycle of mushrooms, countless spores are released from the fruiting bodies. The spores have significant implications in the food and medicine industries due to pharmacological effects attributed to their bioactive ingredients. Moreover, high concentration of mushroom spores can induce extrinsic allergic reactions in mushroom cultivation workers.
