A method for mechanized hybrid rice seed production using female sterile rice.

Background: The breeding and large-scale adoption of hybrid rice is an important achievement in modern agriculture. Mechanized seed production is urgently needed for widespread adoption of hybrid rice because it can compensate for the shortage of manual labor to meet the growing food demands in China.

Results: Here, we report the development of a mechanized hybrid rice seed production method using a female sterile rice.

Natural polysaccharides exhibit anti-tumor activity by targeting gut microbiota.

Natural polysaccharides, the abundant dietary components, show potent antitumor bioactivity in treatment and chemoprevention. Compared with traditional tumor therapy, natural polysaccharides are characterized by the low toxicity and immuno-regulation function. Recent researches have indicated that the anti-tumor of polysaccharides was partly attributable to modification in the composition of gut microbiota when polysaccharides were digested.

Downregulation of ERBB3 decreases the proliferation, migration and invasion of cervical cancer cells though the interaction with MTK-1.

Cervical cancer is a common malignancy in females. Diagnosis and treatment of cervical cancer remains a challenge due to difficulties in the presence of tumor metastasis. Increased expression level of Erb-b2 receptor tyrosine kinase 3 (ERBB3) has previously been demonstrated to be associated with the occurrence of cervical cancer; however, the functionality of ERBB3 in the development of cervical cancer remains incompletely understood.
