Cancer is caused by uncontrolled cell proliferation which has the potential to occur in different tissues and spread into surrounding and distant tissues. Despite the current advances in the field of anticancer agents, rapidly developing resistance against different chemotherapeutic drugs and significantly higher off-target effects cause millions of deaths every year. Osthol is a natural coumarin isolated from Apiaceaous plants which has demonstrated several pharmacological effects, such as antineoplastic, anti-inflammatory and antioxidant properties...

Triphala (Trl) is an ayurvedic formulation used for treating disorders of the digestive, respiratory, and nervous systems. Its anticancer properties have also been documented. We studied effects of Trl on tubulin, a target protein for several anticancer drugs, and systematically elucidated a possible antiproliferative mechanism of action of Trl. Trl inhibited proliferation of HeLa (cervical adenocarcinoma), PANC-1 (pancreatic adenocarcinoma), and MDA-MB-231 (triple-negative breast carcinoma) cells in microgram quantities and strongly suppressed the clonogenicity of HeLa cells...

While endocervical adenocarcinoma is comprised of several histological subtypes, the most common subtype is human papillomavirus-associated usual type, and management of these tumours is primarily determined by FIGO (International Federation of Gynecology and Obstetrics) stage, a clinically based staging system. Early stage cervical cancer is determined by the pathological evaluation of tumour microscopic measurement (depth of invasion), which can be particularly challenging because of the lack of a defined point of origin...

Adenocarcinoma of the cervix is less common than squamous cell carcinoma, although its relative prevalence is increasing. Oncogenic (high-risk) human papillomavirus (HPV) infection is implicated in the development of approximately 90% of all cervical adenocarcinomas. Of the remaining non-HPV associated tumours, the most frequent is gastric-type adenocarcinoma (GAS), which is recognised by the World Health Organization as a form of mucinous adenocarcinoma of the cervix. Minimal deviation adenocarcinoma (MDA) of mucinous type (adenoma malignum) is considered an extremely well differentiated variant of GAS and is encompassed within the category of GAS...
