AI Article Synopsis

  • The study investigates the ability of peptides from camel milk proteins to inhibit key digestive enzymes (DPP-IV, PPA, and PPL).
  • Results showed significant inhibition of DPP-IV and PPL after enzyme hydrolysis, with some effect on PPA.
  • Specific peptides were identified as the most effective inhibitors for each enzyme, showcasing the potential health benefits of camel milk proteins.

Article Abstract

In-vitro inhibitory properties of peptides released from camel milk proteins against dipeptidyl peptidase-IV (DPP-IV), porcine pancreatic α-amylase (PPA), and porcine pancreatic lipase (PPL) were studied. Results revealed that upon hydrolysis by different enzymes, camel milk proteins displayed dramatic increase in inhibition of DPP-IV and PPL, but slight improvement in PPA inhibition was noticed. Peptide sequencing revealed a total of 20 and 3 peptides for A9 and B9 hydrolysates respectively, obtained the score of 0.8 or more on peptide ranker and were categorized as potential DPP-IV inhibitory peptides. KDLWDDFKGL in A9 and MPSKPPLL in B9 were identified as most potent PPA inhibitory peptide. For PPL inhibition only 7 and 2 peptides qualified as PPL inhibitory peptides from hydrolysates A9 and B9, respectively. The present study report for the first time PPA and PPL inhibitory and only second for DPP-IV inhibitory potential of protein hydrolysates from camel milk.

Background: Equine milk, including its whey proteins, is a source of nutrients and functional components in the human diet, and is especially beneficial for people with weakened immune systems, newborns, and athletes. Objectives Whey proteins in equine milk constitute approximately 20% of the total protein content and include various fractions such as albumin, globulin, and lactoferrin. Lactoferrin is one of the most extensively studied whey proteins in equine milk.

The Dromedary camel has a remarkable history amongst cultures across Asia and northern Africa, serving multiple purposes ranging from providing milk, textiles, racing, and acting as pack animals. Recent genetic studies have revealed that many dromedaries are genetically homogenous, indicating that they do not represent different breeds, advocating for camel 'type' over camel 'breed'. In this study, we leveraged whole genome sequencing (WGS) to sequence 15 Jordanian Alia camels for the first time, alongside 9 Jordanian mixed camels from diverse locations within the country.

Nanobody-based indirect competitive ELISA for the detection of aflatoxin M1 in dairy products.

Sci Rep

January 2025

Key Laboratory of Dairy Biotechnology and Engineering, Ministry of Education, College of Food Science and Engineering, Inner Mongolia Agricultural University, Hohhot, 010018, China.

Aflatoxin M1 (AFM1) is known to be carcinogenic, mutagenic, and teratogenic and poses a serious threat to food safety and human health, which makes its surveillance critical. In this study, an indirect competitive ELISA (icELISA) based on a nanobody (Nb M4) was developed for the sensitive and rapid detection of AFM1 in dairy products. In our previous work, Nb M4 was screened from a Bactrian-camel-immunized phage-displayed library.

Background: The effects of camel milk in inflammation and systemic oxidative stress of cigarette smoke (CS)-induced chronic obstructive pulmonary disease (COPD) associated with small airway inflammation in rats were investigated.

Methods: 35 male Wistar rats were randomly divided into five groups: (a) control, (b) CS-exposed rats, c and (d) CS-exposed rats treated with the 4 and 8 mL/kg camel milk, and (e) CS-exposed rats treated with 1 mg/kg dexamethasone.

Results: Total and differential WBC counts, serum level of TNF- and malondialdehyde (MDA) level in serum and homogenized tissues of the heart, kidney, liver, and testicle were significantly increased, but catalase (CAT), superoxide dismutase (SOD) and thiol levels were significantly decreased in CS-exposed rats ( < 0.
