ZNF671 Silencing Affects Signaling Pathways in Head and Neck Cancer via Activation of Oncogenic Non-Coding RNAs.

Background: Novel ZNF genes, such as ZNF671, that are located on chromosome 19q13 are known to be hypermethylated at a high frequency in HNSCC as well as in other epithelial solid tumors. Their function is largely unknown.

Results: Here, we show that ZNF671 is epigenetically silenced in HNSCC primary tumors compared to matched adjacent normal tissue.

Comprehensive functional evaluation of head and neck squamous cell carcinoma with BH3-profiling demonstrates apoptotic competency and therapeutic efficacy of BH3-mimetics.

Evasion of apoptosis promotes tumor survival and contributes to resistance to cancer therapeutics in head and neck squamous cell carcinoma (HNSCC). Our recent work has demonstrated that HNSCC's highly express pro-survival anti-apoptotic proteins Bcl-xL and Mcl-1. Nevertheless, the mechanism of HNSCC to evade apoptosis is still not well understood.

CYP76BK1 orthologs catalyze furan and lactone ring formation in clerodane diterpenoids across the mint family.

The Lamiaceae (mint family) is the largest known source of furanoclerodanes, a subset of clerodane diterpenoids with broad bioactivities including insect antifeedant properties. The Ajugoideae subfamily, in particular, accumulates significant numbers of structurally related furanoclerodanes. The biosynthetic capacity for formation of these diterpenoids is retained across most Lamiaceae subfamilies, including the early-diverging Callicarpoideae which forms a sister clade to the rest of Lamiaceae.
