HO-1197 as a Multifaceted Therapeutic: Targeting the Cell Cycle, Angiogenesis, Metastasis, and Tumor Immunity in Hepatocellular Carcinoma.
Article in International journal of molecular sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Hepatocellular carcinoma (HCC) is the most prevalent primary malignancy of the liver. Characterized by rapid progression and poor overall survival rates, HCC requires effective and streamlined treatment regimens. It predominantly occurs in East Asia and sub-Saharan Africa, where it has historically been managed with herbal formulas. We previously observed that the herbal formula HO-1089 exerts potent anti-HCC effects both in vitro and in vivo. In this study, we investigated the anticancer efficacy and mechanisms of HO-1197, a reconstituted herbal formulation derived from HO-1089. HO-1197 selectively inhibited the viability of HCC cell lines without hepatotoxicity and demonstrated superior anticancer activity compared with both HO-1089 and sorafenib. Mechanistically, HO-1197 induced apoptosis and G2/M arrest through reactive oxygen species-mediated DNA damage, independent of p53 status. Transcriptomic analysis revealed downregulation of mitosis-related genes, particularly those regulated by FOXM1, a key driver of HCC proliferation and metastasis. HO-1197 suppressed FOXM1 expression and nuclear translocation, reducing its downstream targets and diminishing angiogenic and metastatic potential. Furthermore, HO-1197 modulated the tumor immune microenvironment by promoting pro-inflammatory macrophage polarization and enhancing natural killer cell-mediated cytotoxicity. HO-1197 exhibited potent antitumor efficacy, and combination therapy with HO-1197 and sorafenib exhibited synergistic effects in both two-dimensional and immune-activated multicellular spheroid models. These findings suggest that HO-1197 is a promising multifunctional therapeutic candidate with antitumor, antiangiogenic, antimetastatic, and immunomodulatory properties. Its combination with sorafenib may offer effective treatment for HCC. HO-1197, which demonstrated strong efficacy, is a novel herbal medicine developed by H&O Biosis and is referred to as an Integrated Natural Medicine.
