NACC1 (Nucleus Accumbens Associated 1)

OXPHOS augmentation (by α-ketoglutarate [αKG]) or suppression (by metformin) disrupt Treg metabolism. Finally, indoleamine 2,3-dioxygenase (IDO) seems to affect Tregs and can be a promising target in advanced immunotherapy naïve cancer patients. The focus of this review is to describe Treg metabolic regulators/connectome and opportunities they bring about in cancer therapy.

Three variant of uncertain significance of IDH1 and NACC1 were found and deserve further investigation for their pathogenic role. Data from the present study suggest the potential benefit of targeted therapy, in particular drugs in the mTOR pathway, for these patients.

The metabolomic analysis demonstrated that NAC1 promotes truncated gluconeogenesis and de novo serine synthesis through PCK2 upregulation. These findings suggest that NAC1 contributes to ovarian cancer progression by promoting metabolic adaptation, highlighting the NAC1-PCK2 axis as a potential therapeutic target for ERONs.

Histologically, it is characterized by a monomorphic ovoid cell proliferation with a tubulo-solid growth pattern and focal thyroid-like morphology. Neuroendocrine marker expression is variable, but strong and diffuse alpha-inhibin staining is a consistent feature.

Mechanistically, circNRIP1 interacted with the K homology_1/2 domain of IGF2BP1 and blocked its m6A reader activity, and further reduced the stability of NACC1 mRNA and inhibited colorectal tumorigenesis. circNRIP1 is an important tumor suppressor in CRC tumorigenesis and blood exosomal circNRIP1 could be an early diagnostic biomarker for CRC.

ChIP assays confirmed in vivo binding of NAC1 to the promoter. The present study implicated that NAC1 may contribute to the development of ERONs as a transcriptional repressor by regulating ACOX2 expression via specific binding sites on the promoter, providing a novel insight into the NAC1/ACOX2 axis as a potential therapeutic target of this tumor type.

These findings establish unique gene signatures for these variants of ST-iCCA, providing potential biomarkers for differential diagnosis, prognosis and targeted therapy. The distinct genetic profiles may also uncover novel therapeutic targets to address the aggressive nature of ST-iCCA.

Nomenclature of the cholangioblastic variant is in evolution as is the link between adenofibroma and the tubulocystic variant. Correct recognition of these variant subtypes would aid in long-term studies to better determine the prognosis in these subtypes.

These results implied the heterogeneity of molecular pathophysiology of canine LCGIL. Further studies are needed to comprehensively analyze genomic and non-genomic molecular aberrations in each canine LCGIL case.

In addition, the AKT activator SC79 restored the inhibited cell proliferation after NACC1 knockdown and ADAM9 knockdown. In conclusion, our study suggested that the NACC1/ADAM9/PI3K/AKT axis is crucial for sustaining the survival of AML cells, indicating that NACC1 may be a viable target for treating AML.

Expression profiling demonstrated alterations in the transforming growth factor receptor beta superfamily, and overexpression of MYC which was validated by immunohistochemistry. Our findings expand the morphologic and genetic spectrum of this neoplasm and provide insight into secondary genetic changes associated with progression.
