The role of T-lymphocytes in natural cytotoxicity of splenocytes of C3HA mice after a single injection of 20-methylcholanthrene (20-MC) was investigated. A splenocyte suspension was treated with anti-T-cell serum and complement. This treatment was not shown to exert influence on the natural cytotoxicity of splenocytes within 1-13 days after injecting 20-MC.

Bone defects caused by fractures and diseases often do not heal spontaneously. They require external agents for repair and regeneration. Bone tissue engineering is emerging as a promising alternative to traditional therapies like autografts and allografts.

Introduction: The mortality rate for liver cancer is extremely high but clinical treatments have not made much progress, so it is necessary to develop anticancer agents with lower toxicities and more effective liver-targeting drug delivery systems (LTDDSs). At present, LTDDSs mediated by the asialoglycoprotein receptor (ASGPR) show excellent effects at improving the liver-targeting and antitumor effects of drugs. However, the galactosyl ligands are typically prepared by chemical synthesis and have some shortcomings.

c-Myc is a transcription factor that is overexpressed in most human cancers. Despite its challenging nature, we have developed a series of naphthalimide-imidazopyrazine conjugates to target c-Myc. The library of synthesized derivatives was tested for their anticancer activity against a nine-panel of cancer cell lines.

Essential oils (EOs) exhibit a broad spectrum of biological activities; however, their clinical application is hindered by challenges, such as variability in chemical composition and chemical/physical instability. A critical limitation is the lack of chemical consistency across EO samples, which impedes standardization. Despite this, evidence suggests that EOs with differing chemical profiles often display similar (micro)biological activities, raising the possibility of standardizing EOs based on their biological effects rather than their chemical composition.

Background: Lung cancer is a highly aggressive tumor with limited therapeutic options. The misregulation of Androgen Receptor (AR) signaling has been observed in lung cancer. Therefore, inhibiting AR signaling is a promising strategy for treating lung cancer.
